Do not attempt any electrical repairs unless fully competent.
Do not attempt any maintenance or inspection of the feed mechanism without switching
machine to off or there is a risk of bodily crush damage in the wire feed.
The welding torch & wire feed roller mechanism needs to be checked & cleaned regularly to
ensure best performance; the torch liner will need replacing after a few rolls of wire or every
few months.
The wire feed roller should need be replaced each year for optimum feeding.
Contact your supplier for assistance with any faults.
It is necessary for a comprehensive service inspection and test to be carried out at regular
intervals by a competent person and documented. This should be no less than every 12
months and sooner in harsh operating conditions.
If correctly maintained this machine should give a long trouble free life.
Trouble shooting guide
Problem
Machine stops welding after a period of use on higher settings but fan still runs
Solution
Possible overheated transformer caused by duty cycle being exceeded, leave machine switch
on for around half an hour & retry, ideally reduce output power or welding time to prevent re-
occurrence. Otherwise damage can occur.
Problem
Machine stops welding & fan also stops.
Solution
Possible mains supply failure or blown mains fuse, replace fuse & check supply is OK
Problem
Machine stops welding but fan still runs
Solution
Possible torch fault or PCB fault, remove welding torch, remove the wire tensioner device so
wire cannot feed, using a short link wire connect together the two contact sockets on the torch
euro connector on the front of the machine, if the motor then runs & you here a click inside
the machine then it’s a torch fault, if not it’s a possible PCB fault you should contact your
supplier.
Problem
Machine welds but arc is a bit erratic & pulses
Solution
Possible wire feeding fault, check the tension on the wire drive arm, it should not be too high
or too low, around half way is a good setting, check the torch liner is in good condition, renew
if necessary, check the liner is the correct size to match the wire, this is very important as the
wire can oscillate in the torch, normally a blue liner is suitable for 0.6 & 0.8mm wire, a red
liner for 1.0 & 1.2mm only.
Try to keep the torch straight it assists the feeding of wire.
Possible too high a speed setting on the wire speed control.
