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 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 s uitable 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.

3 INTRODUCTION

LHF 250/400/630/800 are thyristor controlled welding rectifiers designed for welding

with coated electrodes, TIG welding and arc air gouging.

The welding rectifiers can be used with the following r emote control devices:

PHA 1, PHA 2, PHA 5, PHB 1, PHB 2, och PHC 2.

An auxiliary control unit is required for T IG welding with high frequency ar c ignition.

LHF 400/630, versions with meters and timed co o lin g fan.

These welding rectifiers are equipped with a volmeter, ammeter and a circuit that

reduces the idle speed of the cooling fan.

The meters allow current and voltage settings to be read from the front of the

rectifier.

To minimise the amount of dust and dirt that is drawn into the rectifier the fan runs at

a reduced idle speed of 300 rpm. When welding with currents greater than 30 A the

fan speed increases to its working speed of around 1350 rpm. A timer relay

maintains the higher speed setting for 6 1/2 minutes after welding has stopped to

ensure adequate cooling of the rectifier.

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.

Enclosure class

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

objects or water. Equipment marked IP23 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.

5 I NSTALLATION

The installatio n must be executed by 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.

S Installation must be carried out by a qualified electrician.

S Check that the welding rectifier is configured for the available mains supply

before connecting it to the mains.

S See Connecting to mains for cable rating and fuse rating.

S Connect the mains cable to the rectifier according to the relevant regulations and

install a suitable fuse in the main fuse box.

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

obstructed.

7 MAINTENANCE

Note!

All guarantee undertakings from the supplier cease to apply if the customer himself

attempts any work in the product during the guarantee period in order to rectify any

faults.

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.

Cleaning

Check regularly that the power source is free from dirt.

How often, and to what extent, cleaning should be carried out depends on the

welding process, arc time, disposition and the surrounding envir onment. It will

normally suffice to blow the power source clean using compressed air (reduced

pressure) once a year.

If the power source is very dirty, brushing and vacuuming are recommended.

S Disconnect the welding power source from the mains current supply.

S Remove the adapter from the socket. Lock the socket to prevent unauthorised

connection.

At fixed installations, the safety switch should be set to the off position. Lock

the switch.

S Remove the power source’s safety plates for best access.

After cleaning, all safety plates must be mounted before you connect the power

source to the mains supply.

8 ORDERING OF SPARE PARTS
