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 keep fumes and gases 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 ear defenders or other hearing protection.
S Warn 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 a s 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.

5 MAINTENANCE
Regularly maintenance is important for reliable and safe operations.
S Blow down the power source with dry, compressed air at a low pressure.
S Cleaning 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.
S Blow clean the wire liner regularly and clean the gas nozzle.
WARNING!
Rotating parts can cause injury, take
great care.
