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.

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 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!

3 INTRODUCTION

LKB 265, LKB 265 4WD, LKB 320 and L KB 320 4WD are step controlled power

sources in a compact design, intended for welding with solid steel, stainless steel or

aluminium wire as well as tubular 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

switching terminal above the wire feed unit.

Application classification

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 the welding power source.

Enclosure class

The IP code indicates the enclosure class, i. e. the degree of protection against penetration by solid

objects or water. Equipment marked IP 23 is designed for indoor and outdoor use.

Application class

The symbol indicates that the power source is designed for use in areas with increased

electrical hazard.

page 12. Read through before you start using the equipment!

The power sources can be equipped with instrument to display the current and

voltage.

The instruments have a hold function and can be calibrated.

A thermal cut--out prevents overheating.Resetting takes place automatically when

the power source has cooled.

6 MAINTENANCE

Regularly maintenance is important for reliable and safe operations.

Only those persons who have appropriate electrical knowledge (authorised

personnel) may remove the safety plates to connect or carry out service,

maintenance or repair work on welding equipment.

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.

The brake hub

The hub is adjusted when delivered, if

readjustment is required, follow the instructions

below. Adjust the brake hub so that wire is slightly

slack when wire feed stops.

S Adjusting the braking torque:

S Turn the red handle to the locked position.

S Insert a screwdriver into the springs in the hub.

Turn the springs clockwise to reduce the braking torque

Turn the springs anticlockwise to increase the braking torque. NB: Turn both

springs through the same amount.

WARNING!

Rotating parts can cause injury, take great care.

7 ORDERING OF SPARE PARTS

LKB is designed and tested in accordance with the EN 60974--1 ( IEC

60974--1) international standard.

It is the obligation of the service unit which has carried out the service or re-

pair work to make sure that the product still conforms to the said standard.

Spare parts are ordered through your nearest ESAB representative, see back cover.

When ordering spare parts, please state machine type and number as well as desig-

nation and spare part number as shown in the spare parts list.

This will simplify dispatch and ensure you get the right part.
