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

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 s afe.

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 p rotectio n 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

LT N 255 are r ectifiers 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.

LT N 255 is equipped with ARC PLUS, a new type of control that with MMA welding

provides a m ore intensive, more concentrated and smoother arc. It reacts quicker

after a short circuiting d rop 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 F orce settings in exceptional circumstances.

When drop welding using stainless steel electrodes a special feature on the machine

can be a ctivated to facilitat e welding.

LT N 255 is available in two designs, one with a central connector and one with an

OKC connector for a TIG torch.

LT N 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 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

Welding cable, cross section 35 mm

LTN 255 are equipped with mains voltage compensation, which m eans 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.

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 m ade using the setting knob. T he 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.
