2SAFETY
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
SInstall and earth the welding unit in accordance with applicable standards.
SDo not touch live electrical parts or electrodes with bare skin, wet gloves or wet clothing.
SInsulate yourself from earth and the workpiece.
SEnsure your working stance is safe.
FUMES AND GASES -- Can be dangerous to health
SKeep your head out of the fumes.
SUse 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.
SProtect your eyes and body. Use the correct welding screen and filter lens and wear protective
clothing.
SProtect bystanders with suitable screens or curtains.
FIRE HAZARD
SSparks (spatter) can cause fire. Make sure therefore that there are no inflammable materials nearby.
NOISE -- Excessive noise can damage hearing
SProtect your ears. Use earmuffs or other hearing protection.
SWarn bystanders of the risk.
MALFUNCTION -- Call for expert assistance in the event of malfunction.
PROTECT YOURSELF AND OTHERS!
ESAB can provide you with all necessary welding protection and 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
LTN 255 are rectifiers designed using inverter technology and are intended for TIG --
welding and welding using coated electrodes.
Inverter technology contributes towards low power consumption, a low weight and
compact dimensions.
The advanced electronics with microprocessor control provides, amongst others,
quick regulation and top class welding characteristics.
LTN 255 is equipped with ARC PLUS, a new type of control that with MMA welding
provides a more intensive, more concentrated and smoother arc. It reacts quicker
after a short circuiting drop transfer, which reduces the risk of the electrode sticking.
In addition, the machine is equipped with Arc Force, which means that the power
source’s dynamics can be adjusted, softer or harder depending on the type of elec-
trode and the welder’s preference.
ARC PLUS -- because of the regulator’s good characteristics it is only necessary to
change the Arc Force settings in exceptional circumstances.
When drop welding using stainless steel electrodes a special feature on the machine
can be activated to facilitate welding.
LTN 255 is available in two designs, one with a central connector and one with an
OKC connector for a TIG torch.
LTN 255 issuppliedcompletewitha5metremainscable,5metrereturncable, gas
hose and hose clips. Machines with a central connector are also fitted with a safety
bar to protect the connectors from impact.
As an accessory there is a loop handle to fit on the machines which acts as a cable
reel as well protecting the control panel. There are also two carriages available for
transportation with a gas cylinder and cooling unit.
ESAB’s accessories for the product can be found on page 28.

5 INSTALLATION
The installation 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.
Mains voltage 400 V ¦10 % , 3--phase
Mains frequency 50--60 Hz
Fuse, slow rupture 16 A
Mains cable, cross section 4x1.5 mm2
Welding cable, cross section 35 mm2
LTN 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 cur-
rent.
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.

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. In addition, the error code ”E13” is displayed. When the temperature has
dropped the thermostat automatically resets.

6.1 Control panel
On the front of the machine there is a control panel for the selection of functions and
setting of parameters. This consists of a display, setting knob, LEDs and push--but-
tons.
By using the push--buttons you can move between the different functions. The se-
lected function is indicated by respective LEDs coming on.
One line at a time is set. The current line is indicated by a red LED. Movement be-
tween lines takes place using the red arrow keys.
Movement within each line takes place using the green arrow keys.
All settings are made using the setting knob. The LEDs to the right of the display
indicate the actual unit (ampere/volt/seconds). On the lines where only a function is
selected, ”------” is shown on the display.
