WARNING

ARC WELDING AND CUTTING CAN BE INJURIOUS TO YOURSELF AND OTHERS. TAKE PRECAUTIONS

WHEN WELDING. ASK FOR YOUR EMPLOYER'S SAFETY PRACTICES THAT SHOULD BE BASED ON

MANUFACTURERS' HAZARD DATA.

ELECTRIC SHOCK - Can kill

Install and earth the welding unit in accordance with applicable standards.

Do not touch live electrical parts or electrodes with bare skin, wet gloves or wet clothing.

Insulate yourself from earth and the workpiece.

Ensure your working óstance is safe.

FUMES AND GASES - Can be dangerous to health

Keep your head out of the fumes.

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.

Protect your eyes and body. Use the correct welding screen and filter lens and wear protective

clothing.

Protect bystanders with suitable screens or curtains.

FIRE HAZARD

Sparks (spatter) can cause fire. Make sure therefore that there are no inflammable materials nearby.

NOISE - Excessive noise can damage hearing

Protect your ears. Use earmuffs or other hearing protection.

Warn bystanders of the risk.

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

READ AND UNDERSTAND THE INSTRUCTION MANUAL BEFORE INSTALLING OR OPERATING.

PROTECT YOURSELF AND OTHERS!

3 INTRODUCTION

LKB 265, LKB 265 4WD, LKB 320 and LKB 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 certain 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.

B - Voltage selector, 10-step

C - Voltage selector, 4-step

D - Main switch, on/off

E - Mains indicator lamp

F - Thermal overload warning lamp, lights up in case of overheating

G - Welding torch connection

H - Potentiometer (wire feed)

J - Inductance connection

K - Potentiometer (spot welding)

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.

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

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 pressure

roller, feed roller and wire liner.

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

- 42-

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.

Adjusting the braking torque:

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)
