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.

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 keep fumes and gases 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 ear defenders or other hearing protection.

SWarn bystanders of the risk.

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

PROTECT YOURSELF AND OTHERS!

3 INTRODUCTION

LKB 265 and LKB 320 are step controlled power sources in a compact design, in-

tended for welding with solid steel, stainless steel or aluminium wire as well as tubu-

lar wire with or without shielding gas.

The possibility of welding with homogeneous wire/shielding gas and welding with

gasless tubular wire is obtained by switching the + and -- connections on the switch-

ing terminal above the wire feed unit.

4 INSTALLATION

WARNING

This product is intended for industrial use. In a domestic environment this prod-

uct may cause radio interference. It is the users responsibility to take adequate

precautions.

Installation must be carried out by a qualified electrician.

Connect the power supply lead using the appropriate fuse in conformance with local

regulations.

Cable areas acc. to Swedish regulations.

Make sure the welding rectifier is not covered or positioned so that cooling is ob-

structed.

5 MAINTENANCE

Regularly maintenance is important for reliable and safe operations.

SBlow down the power source with dry, compressed air at a low pressure.

SCleaning and replacement of the wire feed mechanism’s wear parts should take

place periodically to ensure trouble free wire feed.

Note that an excessive pressure setting can result in abnormal wear on the pres-

sure roller, feed roller and wire liner.

SBlow clean the wire liner regularly and clean the gas nozzle.

WARNING!

Rotating parts can cause injury, take

great care.
