WARNING

READ AND UNDERSTAND THE INSTRUCTION MANUAL BEFORE INSTALLING OR OPERATING.

ARC WELDING AND CUTTING CAN BE INJURIOUS TO YOURSELF AND OTHERS. TAKE PRECAU-

TIONS WHEN WELDING. ASK FOR YOUR EMPLOYER’S SAFETY PRACTICES WHICH SHOULD BE

BASED ON MANUFACTURERS’ HAZARD DATA.

ELECTRIC SHOCK -- Can kill

S Install and earth the welding unit in accordance with applicable standards.

S Do not touch live electrical parts or electrodes with bare skin, wet gloves or wet clothing.

S Insulate yourself from earth and the workpiece.

S Ensure your working stance is safe.

FUMES AND GASES -- Can be dangerous to health

S Keep your head out of the fumes.

S Use ventilation, extraction at the arc, or both, to take fumes and gases away from your breathing zone

and the general area.

ARC RAYS -- Can injure eyes and burn skin.

S Protect y our eyes and body. Use the correct welding screen and filter lens and wear protective

clothing.

S Protect bystanders with suitable screens or curtains.

FIRE HAZARD

S Sparks (spatter) can cause fire. Make sure therefore that there are no inflammable materials nearby.

NOISE -- Excessive noise can damage hearing

S Protect y our ears. Use earmuffs or other hearing protection.

S Warn bystanders of the risk.

MALFUNCTION -- Call for expert assistance in the event of malfunction.

PROTECT YOURSELF AND OTHERS!

ESAB can provide yo u with all necessary welding protection an d accessories.

WARNING!

Read and understand the instruction manual before installing

or operating.

Do not use the power source for thawing frozen pipes.

WARNING!

This product is solely intended for arc welding.

3 INTRODUCTION

LTR 160/200 is a rectifier based on inverter technology and designed for TIG

welding and welding with coated electrodes.

Inverter technology contributes to low energy consumption, low weight and compact

dimensions.

The advanced electronic design permits rapid regulation and first class welding

characteristics.

LTR 160/200 is available in two versions, one with a central socket and one with an

OKC socket for connecting a TIG torch.

LTR 160/200 is supplied complete with 5 metre mains cable, 5 metre return cable,

gas hose and hose clamps.

Versions with a central socket are also supplied with a protective cover to protect

connections from slag.

An optional handle bracket can be fitted to the machine for winding up cables and to

protect the control panel.

Two different trolleys are available to facilitate transport with a gas bottle and cooling

unit.

ESAB’s accessories for the product can be found on page 14.

Application class

Class of enclosures IP 23 IP 23

The welding power sources comply with the requirements set out in IEC 974--1

Cable areas acc. to Swedish regulations.

Application class

The symbol indicates that the power source is designed for use in areas with increased

electrical hazard.

Duty cycle

The duty cycle refers to the time as a percentage of a ten--minute period that you can weld at a cer-

tain load without overloading.

Enclosure class

The IP code indicates the enclosure class, i. e. the degree of protection against penetration by solid

objects or water. Equipment marked IP23 is designed for indoor and outdoor use.

The installatio n must be executed by a professional.

WARNING!

This product is intended for industrial use. In a domestic environment this product may cause radio

interference. It is the user’ s responsibility to take adequate precautions.

*) When welding with max 100 A a 10 A slow rupture fuse is sufficient.

LTR 160/200 are equipped with m ains voltage compensation, which means that a

¦10 % variation in the mains voltage only results in a ¦0,2 % variation in the

welding current.

To reduce the voltage drop when using a long cable it can be advisable to select a

heavier cable cross section.

1. Place the equipment in a suitable place and make sure the rectifier is not cov-

ered or set--up so that cooling is prevented.

2. Make sure the machine is connected to the correct mains voltage.

Earth according to applicable directives.

3. Connect the shielding gas.

4. Connect the T IG torch and the return cable or the MMA welding cables.

The machine is now ready for welding.

6OPERATION

General safety regulations for the handling of the equipment can be found on

page 3. Read through before you start using the equipment!

1 Mains power switch on/off 8 Remote control connection

2 Yellow indicating lamp 9 Dust filter

3 White indicating lamp 10 Gas nipple (connection of gas cylinder)

4 Slope--down time 11 Connection for TIG torch

5 Lift--Arc/HF--unit/MMA 12 Connection for return cable when TIG welding

6 Current setting 13 2/4--stroke

7 Gas post--flow 14 Remote control switch

The welding cable and return cable should be connected to 12 and 15 with MMA--welding.

S Using the remote control socket on the machine the current can be remotely

regulated in TIG and MMA modes.

S Selector switch is used to select remote control operation.

S PHA5 remote control unit allows use of pulsed current in TIG mode.

When the main power switch is switched on the white indicating lamp, on the front,

comes on.

To take your mind off the risk of overloading the machine it has been equipped with

an integrated thermostat that trips if the temperature becomes too high.

When this occurs the welding current is cut out and the yellow indicating lamp comes

on. When the temperature has dropped the thermostat automatically resets.

Mode = HF

When the torch trigger is pressed the gas starts flowing. T he high frequency unit is

switched on and produces a spark between the electrode and the work piece, which

ionises the gas and ignites the arc. Once the arc is stable the HF unit is

automatically switched off.

bt16d12e

Mode = MMA.

In this mode the machine is set up for welding with coated electrodes. The HF unit

and Lift--Arc are disabled and the Hot--start unit is now activated to give a higher

current during striking.

Mode 2/4--stroke

2 stroke: arc is struck when the torch trigger is depressed and extinguished when

the trigger is released.

4 stroke: there is no need to keep the torch trigger depressed during the welding

sequence. Press and release the trigger to strike the arc. Press and release the

trigger again to extinguish the arc.

6.1 LIFTARC

Mode = Lift--Arc.

The torch electrode is positioned at the point where you want to start welding, when

you press the trigger and raise the torch the arc is struck.

Using the built--in slope--up function the current rises to the preset value. When you

want to stop welding you release the switch and the current slowly decreases in

accordance with the preset slope--down time.

Place the electrode against Press in the torch trigger..

7 MAINTENANCE

Regular maintenance is important for safe, reliable operation.

Note!

All guarantee undertakings from the supplier cease to apply if the customer himself

attempts any work in the product during the guarantee period in order to rectify any

faults.

Only those persons who have appropriate electrical knowledge (authorized

personnel) may remove the safety plates to connect or carry out service,

maintenance or repair work on welding equipment.

Generally, LTR 160/200 do not

require any maintenance. Normally,

it is sufficient to blow out the

machine using clean, compressed

air annually, and the dust filter

should be cleaned regularly.

If the machine is set up in dusty or

dirty environments the machine and

dust filter should be cleaned more

often. .

8 ORDERING OF SPARE PARTS

Repair and electrical work should be performed by an authorized ESAB serviceman.

Use only ESAB original spare and wear parts.

LTR 160, LTR 200 is designed and tested in accordance with the international and Eu-

ropean standards IEC/EN 60974--1 and EN 50199. It is the obligation of the service unit

which has carried out the service or repair work to make sure that the product still

conforms to the said standard.

Spare parts may be ordered through your nearest ESAB dealer, see the last page of

this publication.
