Section I

Safety Precautions

WARNING

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.

Wear dry, hole-free insulating gloves and

appropriate body protection.

3. Disconnect input power before installing or

servicing this equipment. Lockout/tagout

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 con-

nected to a properly grounded receptacle

outlet.

6. When making input connections, attach

proper grounding conductor rst - double-

check connections.

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.

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 contact

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.

C. Arc Rays

Arc rays can burn eyes and skin; noise can dam-

age 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 du-

rable, ame-resistant material (wool and

leather) and foot protection where neces-

sary.

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 ex-

haust 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 instruc-

tion for metals, consumables, coatings,

cleaners, and degreasers.

5. Work in a confined 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

galvanized, 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 carefully.

1. Protect compressed gas cylinders from

excessive 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.

3. Keep cylinders away from any welding or

other electrical circuits.

4. Never weld on a pressurized cylinder -

explosion will result.

5. Use only correct shielding gas cylinders,

regulators, hoses and ttings designed for

9900-CWF-50 Cold Wire Feeder

- 3 -

the specic application; maintain them and

associated parts in good condition.

6. Turn face away from valve outlet when

opening cylinder valve.

7. Keep protective cap in place over valve ex-

cept when cylinder is in use or connected

for use.

8. Read and follow instructions on com-

pressed gas cylinders, associated equip-

ment, 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,

explosion, 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

ammable material.

3. Remove all ammables within 35 ft. (10.7

m) of the welding arc. If this is not pos-

sible, tightly cover them with approved

covers.

4. Be alert that welding sparks and hot mate-

rials 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 trou-

sers, 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 trouble-

shooting as necessary.

H. EMF Information

Considerations About Welding and the Ef-

fects of Low Frequency Electric and Magnetic

Fields

The following is a quotation from the General

Conclusions Section of the U.S. Congress, Of-

fice of Technology Assessment, Biological

Effects of Power Frequency Electric & Mag-

netic Fields - Background Paper, OTA-BP-E-53

(Washington, DC: U.S. Government Printing

Ofce, May 1989):

“.... 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

9900-CWF-50 Cold Wire Feeder

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.

Section II

Introduction

The cold wire feeder is designed to supply ller

metal to the weld puddle in a mechanized tung-

sten arc welding application. The system will

accurately feed 0.020”, 0.030”, 0.035”, 0.045”,

0.062” and 0.093” (0.5 to 2.4 mm) hard and soft

wires for mechanized TIG or plasma welding.

The CWF-50-9900 comes with motor/tach

generator cable, but no motor control. It is

specically designed for connection to a 9900-

MCMA1-1 motor control module as part of the

9900 Controller. However, it can be used with

any DC motor controller capable of delivering

0 to 90 volts DC at 1/8 hp. The tach generator

output is approximately 0 to 18 volts DC.

The system consists of a DC motor-driven four

feed roll assembly, spool adapter, and a wire

guide positioner. The positioner incorporates

X-Y-Z movements of the wire tip and includes

a universal torch mounting bracket.

The basic components of the wire feeder are:

(See Figure 1)

1. Wire drive unit: consists of motor, drive

housing, and wire spool assembly to feed

wire. (Part number CWF-50-DA.)

2. WGP-1 Wire Guide Positioner: guides

wire into puddle.

Note: The wire guide positioner can be

used either as a left hand or right hand

assembly. To change conguration as sup-

plied by factory, reverse thumb knob, set

screw, and spring. (See WGP-1 drawing.

item numbers 13, 18, and 24.)

3. Spool adapter: holds 12” (305 mm) diam-

eter wire spools.

4. Wire Feed Accessory Kit: conduit, feed

rolls, inlet guides, outlet guides, and tips

for 0.020”, 0.030”, 0.035”, 0.045”, 0.062”

and 0.093” (0.5 to 2.4 mm) hard and soft

wire. Order kits separately for desired

wire size.

WIRE FEED CONTROL

9900-CWF-50 Cold Wire Feeder

- 7 -

Section III

Installation

As standard, the unit is provided with 6 feet

(1830 mm) of cable between the control and the

wire drive assembly. The control is typically

mounted near the feeder due to the length of the

control cable.

1. To mount the wire drive assembly, trans-

fer mounting holes from the wire feeder’s

aluminum mounting plate to the mount-

ing surface. (See Figure 2 for mounting

hole dimensions.)

2. Slip the wire guide positioner onto the

torch barrel and tighten the wing nuts.

You may choose from one of three sets

of mounting holes depending upon the

brand of the torch to be used.

The wire guide tip angle should be set

roughly by positioning the guide and

tightening the screw. The tip should be

approximately on the same level as the

tungsten.

3. Select the wire feed accessory kit for the

size wire your application requires. The

kit will include inlet and outlet guides,

conduit, wire guide tip, and feed rolls. Be

sure all components match the wire size

to be used. (Refer to Figure 3)

Proper installation of the wire feed kit is

very critical to the successful operation

of the cold wire feed unit. Proper instal-

lation helps avoid “bird-nesting” at the

feed rolls and smooth wire feed delivery

into the weld puddle.

a. The inlet guide should be inserted

until the “set screw” properly aligns

with the notched section on the

guide. The closer the tapered tip is

to the feed rolls the better.

b. The intermediate guide needs to be

inserted prior to the mounting of the

feed rollers. The intermediate guide

also has a “notched” section which

should align with the screw holding

it in position.

c. The feed rolls need to be mounted

securely. If not tightened, they will

loosen and will eventually fall off.

d. The conduit assembly is then tted

into the outlet guide assembly. This

step may need to be repeated in or-

der to t it correctly. First, the end

and inside of the conduit must be

deburred. The wire must slide freely

into the conduit.

Next the conduit should be cham-

fered. The conduit needs to be as

close as possible to the feed rolls

in order to avoid “bird-nesting”,

especially on soft wires. Putting a

chamfer on the conduit allows you

to get the conduit very close to the

feed rolls.

At this point, slide the conduit

through the outlet guide. You

should extend the conduit beyond

the tapered end of the outlet guide

approximately 1/4” (6 mm). Tighten

the set screw securely, holding the

conduit properly in position.

e. Insert the outlet guide/conduit as-

sembly into the drive roll assembly.

Position it so the chamfered conduit

is very close to the drive rolls. (Make

sure the end of the outlet guide is

clear of the drive rolls.) Tighten the

9900-CWF-50 Cold Wire Feeder

- 8 -

outlet guide securely by turning the

hand knob.

f. Run the conduit to the torch as re-

quired. Remember sharp twists and

turns affect the ow of the wire. Test

the path of the conduit with the torch

in its fully retracted and extended

positions.

If the conduit is too long, cut the

end, making sure it is completely

deburred.

g. Strip 4” (100 mm) of the outer cover

on the conduit. Slide the bare con-

duit into the wire guide tip. Tighten

the set screw holding the conduit

securely into position.

Note: On a rare occasion, you may

have to pull this end of the conduit

from the tip when initially feeding

wire. Let the wire extend about 6”

to 8” (150 to 200 mm) beyond the

conduit and then feed the wire into

the tip until the conduit is back into

normal position.

The wire guide tip is held in position

by a set screw. The tip can slide

into the clamping mechanism on the

WGP-1 Wire Guide Positioner.

4. Electrical Connections:

The motor leads require 0 to 90 volts DC

at 1 amp. The tach generator leads output

0 to 25 volts DC, linear with motor speed,

polarity reverses with direction change.

Section IV

Operating Instructions

A. Preparation for Welding

Mount the spool of welding wire on the spool

adapter so the wire will be pulled from the low

side of the coil. Then replace the spool retain-

ing ring. Adjust the friction brake on the wire

spool by adjusting the screw in the center of the

spool. If adjusted properly, the spool will feed

smoothly and will not coast or continue to spin

when feeding stops.

Debur the end of the wire, then insert it into the

inlet guide through the feed rolls and the outlet

guide. (Refer to Figure 3).

Inch the wire forward a little. Trim the wire if

there is a ball on the end of the wire. This step

is especially necessary if feeding wire and us-

ing an arc length control. A ball on the end of

the wire could touch the tungsten when feeding

initially. If the wire contacts the tungsten, you

will get a “ball” on the end of the tungsten. The

operator should stop the weld and re-sharpen

the tungsten. This action could also cause ad-

verse effects with the arc length control.

When the wire is inched forward, this is a good

time to verify the wire’s position. Adjust if

necessary.

Retract wire to desired starting position.

Check wire and wire spool briey. Verify there

is enough wire for the next weld and that the

wire is not wrapped around the spool holder.

At this point, the unit is ready to feed wire.

B. Wire Guide Positioner

Several adjustments are provided on the wire

guide positioner in order to permit the exact

position of the wire as it enters the puddle.

1. Lateral adjustment of 1/4” (1/8” adjust-

ment of tip on each side of weld seam).

(6.4 mm total adjustment, 3.2 mm on

each side.)

2. Vertical adjustment of 1/4” (6.4 mm) tip

to work.

3. Coarse adjustment of guide tip angle, by

loosening screw and setting in approxi-

mate position.

The wire position should be checked at the be-

ginning of the weld.

Jog the wire forward through the control and

make required adjustments on the positioner.

Wire typically enters the weld puddle at the

leading edge of the puddle. The wire should

contact the work piece about .04” (1 mm) in

front of the weld puddle and slide under the

center of the welding arc.

Check tension of drive roll spring. Too much

pressure will deform the wire and too little

pressure will cause wire slippage.

C. 9900 Control

Control of the wire feed parameters is through

the 9900, a computer based control. Welding set-

tings are made in the setup windows (screens).

The following pages show instructions.
