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 your 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 your 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!

Do not use the power source for thawing frozen pipes.
WARNING!
This product is solely intended for arc welding.
3 INTRODUCTION
LTR 255 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 255 is available in two versions, one with a central socket and one with an OKC
socket for connecting a TIG torch.
LTR 255 is supplied complete with 5 m etre 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 22.

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.
Application class
The symbol indicates that the power source is designed for use in areas with increased
electrical hazard.
Enclosure class
The IP code indicates the enclosure class, i. e. the degree of protection against penetration by solid

5 I NSTALLATION
The installatio n must be executed b y 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.
Mains voltage 400 V ¦10 %, 3--phase
Mains frequency 50--60 Hz
Fuse, slow rupture 16 A
Mains cable, cross section 4X1,5 mm

LTR 255 are equipped with mains 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 covered 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 TIG 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 12. 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 T IG m ode.
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 m achine 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. The 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.

bt18d12e
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 a pply 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 255 do not require
any maintenance. Normally, it is
sufficient to blow out the m achine
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 255 is designed and tested in accordance with the international and European
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.
