Safety Precautions

CALIFORNIA PROPOSITION 65 WARNING

This product contains chemicals, including lead,

known to the state of California to cause cancer,

and birth defects or other reproductive harm.

Wash hands after use. §248224

A. Arc Welding

Arc Welding can be hazardous. Protect your-

self and others from possible serious injury or

death. Keep children away. Pacemaker wear-

ers keep away until consulting your doctor.

In welding, as in most jobs, exposure to certain

hazards occurs. Welding is safe when precau-

tions are taken. The safety information given

below is only a summary of the more complete

safety information that will be found in the

Safety Standards listed at the end of this section.

Read and follow all Safety Standards.

Have all installation, operation, maintenance

and repair work performed only by qualied

people.

B. Electric Shock

Touching live electrical parts can cause fatal

shocks or severe burns. The electrode and work

circuit is electrically live whenever the output is

on. The input power circuit and machine internal

circuits are also live when power is on. When

using mechanized wire feed, the wire, wire reel,

drive roll housing and all metal parts touching

the welding wire are electrically live. Incorrectly

installed or improperly grounded equipment is

a hazard.

1. Do not touch live electrical parts.

2.

Wear dry, hole-free insulating gloves and

appropriate body protection.

3. Disconnect input power before installing

or servicing this equipment. Lockout/ta-

gout input power according to OSHA 29

CFR 1910.147 (see Safety Standards).

4. Properly install and ground this equipment

according to the operation manual and

national, state and local codes.

5. Always verify the supply ground-check

and be sure that input power cord ground

wire is properly connected to ground

terminal in disconnect box or that cord

plug is connected to a properly grounded

receptacle outlet.

6. When making input connections, attach

proper grounding conductor rst - double-

check connections.

7.

Frequently inspect input power cord for

damage or bare wiring. Replace cord im-

mediately if damaged - bare wiring can

kill.

8. Turn off all equipment when not in use.

9.

If earth grounding of the workpiece is required,

ground it directly with a separate cable - do not

use work clamp or work cable.

10. Do not touch electrode if you are in con-

tact with the work, ground, or another

electrode from a different machine.

11. Use only well-maintained equipment.

Repair or replace damaged parts at once.

Maintain unit according to manual.

12. Wear a safety harness if working above

oor level.

13. Keep all panels and covers securely in

place.

14. Clamp work cable with good metal-to-

metal contact to workpiece or worktable

as near the weld as practical.

WARNING

9627 Microprocessor Controller

- 8 -

C. Arc Rays

Arc rays can burn eyes and skin; noise can

damage hearing; ying slag or sparks can injure

eyes.

Arc rays from the welding process produce

intense visible and invisible (ultraviolet and

infrared) rays that can burn eyes and skin. Noise

from some processes can damage hearing. Chip-

ping, grinding and weld cooling throw off pieces

of metal or slag.

1. Use approved ear plugs or ear muffs if noise

level is high.

2. Use a welding helmet tted with a proper

shade of lter to protect your face and eyes when

welding or watching.

3. Wear approved safety glasses with side

shields.

4. Use protective screens or barriers protect

others from ash and glare; warn others not to

watch the arc.

5. Wear protective clothing made from durable,

ame-resistant material (wool and leather) and

foot protection where necessary.

D. Fumes and Gases

Fumes and gases can be hazardous to your

health.

Welding produces fumes and gases. Breathing

these fumes and gases can be hazardous to your

health.

1. Keep your head out of the fumes. Do not

breathe the fumes.

2. If inside, ventilate the area and/or use exhaust

at the arc to remove welding fumes and gases.

3. If ventilation is poor, use an approved air-

supplied respirator.

4. Read the Material Safety Data Sheets

(MSDS) and the manufacturer’s instruction for

metals, consumables, coatings, cleaners, and

degreasers.

5. Work in a conned space only if it is well

ventilated, or while wearing an air-supplied

respirator. Always have a trained watch person

nearby.

6. Do not weld in locations near degreasing,

cleaning, or spraying operations. The heat and

rays of the arc can react with vapors to form

highly toxic and irritating gases.

7. Do not weld on coated metals, such as gal-

vanized, lead or cadmium plated steel, unless

the coating is removed from the weld area, the

area is well ventilated, and if necessary, while

wearing an air-supplied respirator. The coatings

and any metals containing these elements can

give off toxic fumes if welded.

E. Cylinders

Cylinders can explode if damaged.

Shielding gas cylinders contain gas under high

pressure. If damaged, a cylinder can explode.

Since gas cylinders are normally part of the

welding process, be sure to treat them care-

fully.

1. Protect compressed gas cylinders from exces-

sive heat, mechanical shocks, slag, open ames,

sparks, and arcs.

2. Install cylinders in an upright position by

securing to a stationary support or cylinder rack

to prevent falling or tipping.

9627 Microprocessor Controller

- 9 -

3. Keep cylinders away from any welding or

other electrical circuits.

4. Never weld on a pressurized cylinder - ex-

plosion will result.

5. Use only correct shielding gas cylinders,

regulators, hoses and ttings designed for the

specic application; maintain them and associ-

ated parts in good condition.

6. Turn face away from valve outlet when open-

ing cylinder valve.

7. Keep protective cap in place over valve

except when cylinder is in use or connected for

use.

8. Read and follow instructions on compressed

gas cylinders, associated equipment, and CGA

publication P-1 listed in Safety Standards.

F. Welding

Welding can cause re or explosion.

Welding on closed containers, such as tanks,

drums, or pipes, can cause them to blow up.

Sparks can y off from the welding arc. The

ying sparks, hot workpiece, and hot equipment

can cause res and burns. Accidental contact of

electrode to metal objects can cause sparks, ex-

plosion, overheating, or re. Check and be sure

the area is safe before doing any welding.

1. Protect yourself and others from ying sparks

and hot metal.

2. Do not weld where ying sparks can strike am-

mable material.

3. Remove all ammables within 35 ft. (10.7 m) of

the welding arc. If this is not possible, tightly cover

them with approved covers.

4. Be alert that welding sparks and hot materials

from welding can easily go through small cracks

and openings to adjacent areas.

5. Watch for re, and keep a re extinguisher

nearby.

6. Do not weld on closed containers such as

tanks, drums, or pipes, unless they are properly

prepared according to AWSF4.1 (see safety

Standards).

7. Connect work cable to the work as close to

the welding area as practical to prevent welding

current traveling long, possibly unknown paths

and causing electric shock and re hazards.

8. Wear oil-free protective garments such as

leather gloves, heavy shirt, cufess trousers,

high shoes, and a cap.

G. Moving Parts

Moving parts, such as fans, rotors, and belts can

cut ngers and hands and catch loose clothing.

1. Keep all doors, panels, covers, and guards

closed and securely in place.

2. Have only qualied people remove guards

or covers for maintenance and troubleshooting

as necessary.

Considerations About Welding and the Ef-

fects of Low Frequency Electric and Magnetic

“.... there is now a very large volume of scientic

ndings based on experiments at the cellular

level and from studies with animals and people

which clearly establish that low frequency

magnetic elds can interact with, and produce

changes in, biological systems. While most of

this work is of very high quality, the results are

complex. Current scientic understanding does

not yet allow us to interpret the evidence in a

single coherent framework. Even more frustrat-

ing, it does not yet allow us to draw denite

conclusions abut questions of possible risk or to

offer clear science-based advice on strategies to

minimize or avoid potential risks.”

To reduce magnetic elds in the work place, use

the following procedures:

1. Keep cables close together by twisting or

taping them.

2. Arrange cables to one side and away from

the operator.

3. Do not coil or drape cables around the

body.

4. Keep welding power source and cables as

far away as practical.

5. Connect work clamp to workpiece as close

to the weld as possible.

About Pacemakers:

The above procedures are among those also

normally recommended for pacemaker wearers.

Consult your doctor for complete information.

Introduction

This detailed technical manual is meant to be

used in conjunction with the 9627 Quick Start

manual and the manual for the carriage which

you have purchased. The Quick Start manual

is written for the operator and deals only with

the routine operation of the control. This tech-

nical manual provides details of the set up and

calibration procedures for the control as well as

providing information about the interfacing of

the system with other 9600 series controls and

ancillary controls. It also provides troubleshoot-

ing and maintenance information.

The 9627 microprocessor controller has been

developed to provide high quality, precision

control of all Jetline longitudinal welding car-

riages. The quality design and workmanship of

this control will provide many years of depend-

able service. Its modern technology will help

to provide you with top quality repeatable weld

results. The 9627 is one of a series of micro-

processor controls, all of which have the same

hardware design. Each 9600 series control is

rendered unique by its own custom designed

rmware to facilitate the set up and operation

of the control.

The 9627 control is a microprocessor based

control designed and built to provide low cost,

accurate, repeatable control of the carriage drive

motor. It is available in two versions:

9627 This control includes a motor controller

and can therefore be connected directly

to the carriage drive motor. It is used

for motors up to ½ HP of the type used

on Jetline standard travel carriages. It

provides linear travel speed accuracy

levels suitable for most conventional

applications.

9627-0 This control does not include a motor

controller. Instead, it provides a 0 to

+10VDC enable contact which can

be used to control a precision motor

control module and a precision motor

or a module for a higher horsepower

motor . With the precision module and

motor, the unit can be used for the most

demanding applications where the

ultimate in accuracy and consistency

are demanded.

The system has three modes of operation. Please

turn to the indicated page to obtain more details

of these modes.

Operator Mode:

This is the mode used by the welding operator

to run the unit. It permits travel speed, start and

stop delays and weld time to be adjusted.

Turn to page 15

Setup Mode:

This mode is used during the setting up of the

unit. It permits the setting of the jog speeds, arc

wait and home sequence modes.

Turn to page 20

Calibration Mode:

In this mode, the closed loop can be turned on

and off, the unit can be set for inch or metric

units and the calibration can be checked and

set.

Section IV.

Description

The 9627 control is a microprocessor-based

control designed for the control of longitudinal

welding carriages. The 9627 is one of a series

of controls designed for ease-of-use and for

accurate control of various drive motors for

different weld applications.

The 9627 is packaged in a conveniently-sized

enclosure with Amphenol connectors. The en-

closure has four mounting holes to permit it to

be fastened to the face of a travel carriage or to a

control podium. The front panel is a membrane

overlay with a backlit LCD display and switches

to control the setup and operation of the unit.

The 9627 control has been designed to be easy

to use. Its operation is made easier by the use of

the display which guides you through the setup

process and, during the welding sequence, tells

you what is happening.

The display has two lines of text, the upper line

is the primary one. This is the line that is used

to set the value of the parameter you are setting.

This is done by calling up the line for the param-

eter required and then turning the adjust knob to

increase or decrease the value. The second line

is used to display status messages (information)

about the progress of the weld sequence to let

you know what stage the process is in. Most of

these messages are normally only displayed after

the start push-button has been pressed.

The push-button power switch is used

to provide primary power to the 9627

control. The rst press of the switch

turns on the control. The screen will

become active and display the start-up message.

A second press of this push-button switches the

control off.

These two touch pads are used to scroll

the display up and down. The down

touch pad scrolls down the display

- this takes you through the various

control options in a logical order. The up touch

pad is used to go back through the lines of the

display options. In the standard operating mode

of the 9627 control, these touch pads have no

other purpose.

The adjustment knob is used to change

the value which is currently displayed.

You will note that the knob “incre-

ments”, each incremental movement

of the knob increases the value by its smallest

increment. If the knob is rotated quickly, you

will see that the numbers increase or decrease

faster. The knob can be used to preset the speed

before the motor starts or to change the speed

when the motor is running.

These two touch pads are used to

jog the travel in a reverse or for-

ward direction. When the touch

pad is pressed, travel will begin in the direction

selected and will continue as long as the pad is

pressed. When the touch pad is released, travel

will stop. In addition to the jog facility provided

by the touch pads, they are capable of providing

two more functions.

Rapid Jog: This is achieved by pressing the

forward or reverse touch pad for a short time,

releasing it and then quickly pressing it again.

Travel will start and, after a short time, will

speed up to the “rapid” speed. Rapid travel will

continue until the touch pad is released.

Maintained Jog: This is achieved by first

pressing the forward or reverse touch pad and,

while still pressing this touch pad, pressing

and releasing the start button. The forward or

reverse switch can then be released. The travel

will rotate at rapid speed until it is stopped by

pressing the stop button. This feature is useful

for moving the carriage through a considerable

distance to a desired position.

Depressing and releasing the start

push-button will start the weld se-

quence which will continue until

the stop or emergency stop button is

pressed. Pressing the start push-button while

the forward or reverse touch pad is pressed will

initiate maintained, rapid speed linear travel.

Depressing and releasing the stop

push-button will stop the weld se-

quence.

The emergency stop push-button is a

large, red mushroom-headed switch

designed to stop all operations quickly

in the event of an emergency. When

pressed, the travel will be immediately stopped

and power will be removed from the motor. To

reactivate the system, the switch must be reset

by being pulled out. After reactivation, travel

must be restarted in the normal way using the

start button.

Modes of Operation

A. Operator Mode

This is the mode which is used by the operator

to run the longitudinal carriage. The system is

automatically set to this mode when the control

is switched on.

To set the conditions for operation, the operator

can scroll through the various screens and make

the appropriate changes. These changes will be

displayed on the top line of the display.

As the system is operating, various informa-

tion messages appear on the lower line of the

display.

Display Screens - Upper Line

Screen 1 WELCOME SCREEN

This screen appears automatically when the unit

is switched on and remains on the screen for ap-

proximately 3 seconds. It identies the model

of the control.

The next screen will appear automatically.

Screen 2 TRAVEL SPEED

When the second screen appears, it displays

the current level of travel speed. If this speed

is correct, the start button can be pressed to im-

mediately initiate the weld sequence. If a start

delay has been programmed, travel will start

after the start delay time has elapsed.

Jetline Engineering

Model 9627

TRAV SPEED 10.0ipm

Speed will be displayed in IPM (inches per min-

ute) or CPM (centimeters per minute). Selection

of IPM or CPM is made in the calibration mode

(see Screen 35).

If it is desired to change the speed, this is done

by turning the adjust knob to increase or de-

crease the speed as necessary. As the change

is made, the number on the display changes

accordingly.

The travel speed can be adjusted from the mini-

mum to maximum value which has been set in

the calibration mode (see Screens 26 and 29).

Press the scroll down arrow to proceed to the

next screen.

Screen 3 TORCH LIFT

This screen permits you to manually operate

the torch lift. When the screen reads Out, the

torch lift will be in a retracted position prior to

the start of the weld sequence. The pneumatic

torch lift can be lowered by turning the adjust

knob to In. No other screen can be selected

until the adjust knob is turned to place the torch

in the Out position.

Press the scroll down arrow to proceed to the

next screen.

Screen 4 START DELAY

This screen allows a start delay to be set by

turning the adjust knob to increase or decrease

its value. As the change is made, the number

on the display changes accordingly.

The start delay initiates when the “Arc On” sig-

nal has been received from the welding power

supply. If arc wait mode is Off, the start delay

START DELAY 2.8sec

TORCH LIFT Out

9627 Microprocessor Controller

- 16 -

initiates when the contactor signal is given to

the welding power supply (at the end of PTL

start delay time).

The start delay is used to start travel at the cor-

rect time in the weld start up sequence. If the

9627 controlled carriage is part of a system and

a power supply with current upslope is being

used, it is recommended to initiate travel when

the current has sloped up to about 50% of its

weld value. This will ensure that the weld pool

is correctly established before travel starts. If

the total time for initial current and upslope is

set to 2 seconds on the welding power supply,

a travel start delay of approximately 1 second

would be appropriate.

The start delay can be set from 0 to 99.9 sec-

onds.

Press the scroll down arrow to proceed to the

next screen.

Screen 5 STOP DELAY

This screen allows a stop delay to be set by turn-

ing the adjust knob to increase or decrease its

value. As the change is made, the number on

the display changes accordingly.

When the stop push-button is pressed (or when a

remote stop signal is received), travel will con-

tinue until the stop delay has timed out. After the

stop delay has elapsed, the carriage will stop.

The stop delay time can be set from 0 to 99.9

seconds.

The stop delay is used to stop the travel at the

correct time in the weld sequence. If the 9627

controlled carriage is part of a system and a

power supply with current downslope is be-

ing used, it is recommended to stop the travel

when the current has sloped down to the nal

current level. If, for example, the total time

for downslope is set to 10 seconds, a travel stop

delay of 10 seconds would be appropriate. This

will produce an acceptable weld taper and avoid

a crater crack in the end of the weld.

Press the scroll down arrow to proceed to the

next screen.

Screen 6 WELD TIMER

This screen allows the weld timer to be activated

or deactivated by turning the adjust knob to

select On or Off.

If the weld timer is set to On, the weld length

will be controlled by time. The weld time will

commence at the same time as the start delay

time. At the end of the weld time, the stop delay

will be initiated and a signal will be sent to the

power supply (if one is interconnected) to initiate

the downslope and nal weld sequence.

If the weld timer is set to Off, the weld length

will be controlled manually by pressing the stop

push-button, this will initiate the downslope and

stop delay time (if one has been programmed).

An alternative method of controlling the length

of the weld is by an external signal. The longitu-

dinal carriage and track could be tted with limit

switches. If this is the case, the switches can be

used to dene an end of travel position and can

be used to send a signal to the 9627 control to

initiate the stop sequence. An encoder controller

could also be interconnected.

Press the scroll down arrow to proceed to the

next screen.

If the weld timer has been set to On, the fol-

lowing screen will appear.

Screen 7 WELD TIME

This screen allows the length of the weld time to

be set by turning the adjust knob to increase or

decrease its value. As the change is made, the

STOP DELAY 3.9sec

number on the display changes accordingly.

The weld time can be set from 0 to 999.9 sec-

onds.

Press the scroll down arrow to proceed to the

next screen.

Screen 8 TRAVEL SPEED (Locked)

This is the nal control screen and it is similar to

screen 2. However, with this screen displayed,

it is impossible to change to the travel speed

setting. This screen has been created so that any

accidental movement of the adjust knob cannot

inadvertently affect the travel speed setting.

To change the travel speed, press the scroll up

The second line of the display is reserved for

messages that inform the status of the system.

These messages fall into one of three catego-

ries:

• Messages that appear prior to welding.

• Messages that can appear at any time.

• Messages that appear during a weld se-

quence.

PRE-WELD MESSAGES

Speed Adjustment Locked

This message is displayed when the operation of

the adjust knob is locked out. When this mes-

sage is displayed, the adjust knob has no effect

and the travel speed cannot be altered.

High Limit

This message will be displayed whenever the

adjust knob is turned clockwise and the upper

limit of the parameter being adjusted has been

reached. The message remains on the screen

until the value is reduced below the limit.

This message also appears during welding if the

upper limit of speed is reached, in this case, the

message appears only as long as the adjust knob

is being turned clockwise.

Low Limit

This message is displayed whenever the adjust

knob is turned counterclockwise and the lower

limit of the parameter being adjusted has been

reached. The message will remain displayed on

the screen until the value of the parameter is

increased above the limit.

This message also appears during welding if the

lower limit of speed is reached, in this case, the

message appears only as long as the adjust knob

is being turned counterclockwise.

Jog forward

Whenever the forward jog touch pad is pressed,

the screen will display the message shown above.

Travel will proceed in a forward direction at the

pre-programmed forward jog speed setting (this

speed is set in the setup mode of operation of

the 9627 control - see Screen 9).

Travel will continue as long as the touch pad

is pressed. The message will remain on the

screen for as long as the travel is being jogged

forward.

Jog reverse

Whenever the reverse jog touch pad is pressed,

the screen will display the message shown

above. Travel will proceed in a reverse direction

at the pre-programmed reverse jog speed setting

(this speed is set in the setup mode of operation

of the 9627 control - see Screen 10).

Travel will continue as long as the touch pad

is pressed. The message will remain on the

screen for as long as the travel is being jogged

in reverse.

Rapid jog forward

When the forward jog touch pad is pressed, then

released and then quickly pressed again, after a

short period of time, travel will speed up to the

pre-programmed rapid forward jog speed (this

speed is set in the setup mode of operation of

the 9627 control - see Screen 11).

Travel will continue at rapid speed as long as the

touch pad is pressed. The message will remain

on the screen as long as the carriage is traveling

at this speed.

Rapid jog reverse

When the reverse jog touch pad is pressed, then

released and then quickly pressed again, after a

short period of time, travel will speed up to the

pre-programmed rapid reverse jog speed (this

speed is set in the setup mode of operation of

the 9627 control - see Screen 11).

Travel will continue at rapid speed as long as the

touch pad is pressed. The message will remain

on the screen as long as the carriage is traveling

at this speed.

Maintained forward

When the forward jog touch pad is pressed and

held until the start button is pressed and released,

the carriage will travel forward at maximum

speed and will continue to do so until the stop

button is pressed.

This message remains on the screen as long as

the carriage is traveling forward at maximum

speed.

Maintained reverse

When the reverse jog touch pad is pressed and

held until the start button is pressed and released,

the carriage will travel in reverse at maximum

speed and will continue to do so until the stop

button is pressed.

The message will remain on the screen as long

as the carriage is reversing at maximum speed.

Jogging disabled

This message is displayed when a jog touch pad

is pressed while the system is in any program-

ming screen.

When the control is being set up (start or stop

delays are being set), or whenever the system is

in setup or calibration mode, travel is disabled.

or 8).

ANYTIME MESSAGES

Emergency stop

If the emergency stop button is pressed, the

above message will be displayed. This can oc-

cur at any time and the message will remain on

the screen until after the emergency stop button

is reset by pulling out the knob.

DURING WELD MESSAGES

PTL start delay

This message will be displayed after the start

button has been pressed (or a remote start signal

has been received) and during the time that the

PTL start delay is timing out. Time counts down

from the pre-programmed value to zero.

This message will only be displayed if the auto-

matic torch lift facility is set to On in the set-up

mode (see Screen 16)

Waiting for arc on

At the end of the PTL start delay time, the 9627

sends a signal to the welding power supply to

initiate the arc. If the arc wait mode (Screen

12) has been set to On, this screen will be dis-

played until the control has received a signal

from the power supply indicating that the arc

has been correctly established. This avoids the

weld sequence starting before the arc is fully

established.

Start delay

The travel start delay will be initiated and the

above message will be displayed as follows:

When the start signal (local or remote) is given

(if Auto torch lift is Off or PTL start delay time

is 0)

At the end of the PTL start delay time (if arc wait

mode is Off and Auto torch lift is On)

After the arc has been established (if arc wait

mode is set to On)

Time counts down from the pre-programmed

value (as set in Screen 4) to zero. At the end

of this time, the carriage starts traveling at the

pre-programmed travel speed.

Sensing delay

After any of the above delays have timed out,

and following the initiation of the travel, this

message will be displayed (providing that

Closed Loop Mode is On, Screen 22).

The message will continue to be displayed dur-

ing the time that the closed loop sensing delay

is timing out. Time counts down from the

pre-programmed value (as set in Screen 24) to

zero. During this time, the travel speed runs in

open loop.

Weld Time

If the Weld Timer is set to On (screen 6) and

after the arc has been established, the weld time

is started. The weld time is displayed and counts

down from the pre-programmed value (as set in

Screen 7) to zero.

If the Weld Timer is set to Off (screen 6), the

weld time will be displayed when the arc is

initiated and will count up to indicate the weld

elapsed time.

Stop delay

The above message will be displayed after the

stop push-button is pressed, the weld timer has

timed out or a remote stop signal has been given

to the 9627 control. Time counts down from

the pre-programmed value to zero. During this

time the travel continues at the pre-programmed

travel speed. At the end of the stop delay time,

the carriage stops.

PTL stop delay

This message will be displayed after the travel

has stopped and during the time that the PTL stop

delay is timing out. Time counts down from the

pre-programmed value to zero.

This message appears when the welding system

is tted with a solenoid-operated pneumatic

torch lift and Screen 16 is switched to On.

The torch lift moves the torch away from the

part to provide clearance for unloading.

Home delay

This message will be displayed after the PTL

stop delay time has elapsed, or if there is no PTL

stop delay, at the end of the stop delay time.

Time counts down from the pre-programmed

value to zero.

At the end of the Home Delay time, the carriage

will travel at maximum speed in reverse until the

home limit switch is encountered.

Returning Home

This message will be displayed whenever the

carriage is traveling back to the home position

at the end of the weld.

At Forward Limit

This message will be displayed whenever

the forward jog touch pad is pressed and the

carriage is at the forward limit. Under these

circumstances, jogging in this direction is not

possible. It will be necessary to jog the carriage

in the reverse direction to move away from the

limit switch.

At Reverse Limit

This message will be displayed whenever the

reverse jog touch pad is pressed and the carriage

is at the home limit. Under these circumstances,

jogging in this direction is not possible. It will

be necessary to jog the carriage in the forward

direction to move away from the limit switch.

Reset to Proceed

This message will be displayed whenever the

manual torch lift (Screen 3) is selected to the In

position. This will cause the torch lift (if tted)

to operate to bring the torch into the weld posi-

tion. This facility is provided to permit the torch

to workpiece relationship to be checked before

the weld sequence is started. In this condition,

the scroll touch pads are deactivated.
