PARTS AND SERVICE CONTACTS

Your Clarke Mig Welder has been designed to give long and trouble free service. If,

however, having followed the instructions in this booklet carefully, you still encounter

problems, the following points should help identify and resolve them.

PROBLEM CAUSE REMEDY

1. No “life” from welder Check fuses and mains lead a) Replace fuses as necessary If

problem persists return welder to

your local dealer

b) Check fuse size

2. No wire feed Motor malfunction Return welder to your local dealer

3. Feed motor operates a) Insufficient Feed Roller Pressure a) Increase roller pressure

but wire will not feed b) Burr on end of wire b) Re-cut wire square with no burr

c) Liner blocked or damaged c) Clean with compressed air or

replace liner.

d) Inferior wire d) Use only good “clean” wire

e) Roller worn out e) Replace roller

4. Wire welds itself to tip a) Wire feed speed too low a) Unscrew tip, cut wire and fit new tip

Increase wire speed before

operating again

b) Wrong size tip b) Fit correct size tip

5. Wire feeds into ‘birds a) Wire welded to tip a) As above plus reduce feed roller

nest’ tangle pressure so that if blockage occurs

wire slips on roller i.e. no feed

b) Wire liner damaged preventing

smooth operation b) Renew wire liner

6. Loose coils of wire Drum brake too slack Tighten drum brake

tangle around wire Caution: Do not over-tighten

drum inside machine

7. Erratic wire feed a) Drum brake too tight a) Loosen drum brake slightly

b) Feed roller worn b) Check and replace if necessary

c) Insufficient pressure on feed roller c) Increase pressure on feed roller

Caution: Do not over-tighten

d) Wire dirty, rusty, damp or bent d) Re-cut wire and ensure it is clean

e) Liner partially blocked e) Clean with compressed air

8. Poor quality welds a) Insufficient gas at weld area a) Check that gas is not being blown

away by draughts and if so move

to more sheltered weld area. If not

increase gas supply

b) Incorrect gas/wire combination b) Consult your MIG welding manual

for correct set-up

c) Rusty, painted, damp, oil or c) Ensure workpiece is clean and dry

greasy workpiece

d) Rusty/dirty wire d) Ensure wire is clean and dry

e) Poor earth contact e) Check earth clamp/workpiece conn

9. Wire jams in tip when Tip too small Use slightly oversize tip ie., for .8mm

welding aluminium wire use 1mm tip. (Note: Applies to

aluminium only)

10. Welder cuts out Duty cycle exceeded Allow welder to cool 15-30 mins

whilst in use (auto cut-out operates) before continuing

Note: If duty cycle is continually

exceeded, damage to the welder

may result, and welder output is

probably too small for application

If you have any problems which cannot be resolved by reference to the above, or if you

require spare parts for your welder please contact your local Clarke dealer.
