4 Feed roll pressure is not excessive. The
pressure should be just sufficient to feed
the wire evenly. Excessive pressure will
deform the electrode wire and make
feeding more difficult;
5 Consumable wire spool holder rotates
smoothly and that the braking action is
not excessive. The spool should only have
sufficient braking to prevent over run
when the motor stops. This also may be
conveniently checked each time the wire
is replenished;
7 Welding wire is straight and free of
buckles or ‘waviness’. To check, remove
2 or 3 metres of wire from the spool.
Clamp one end in a vice or similar, then
holding the other end pull the wire out
straight. Look down the length of the
wire, any buckles will be obvious. Buckled
wire is extremely difficult to feed reliably
and should be replaced;
8 Welding wire is free of surface rust.
Replace if rust is evident.
9 External Trouble Shooting
If the following checks do not
identify the fault condition, the
equipment should be returned
to a WIA Service agent. Phone
1300 300 884 for details of your
nearest service agent.
Power source has no output and no
wirefeed when gun switch is closed :
Power light on front panel is off
1 Check equipment is connected to a
functional mains power outlet. Test outlet
using a known working appliance.
2 Check the equipment is switched on,
ie stanby/operate switch is in operate
position.
3 Check the circuit breaker – located on
the inside panel next to the wire feeder
controls (press to reset).
Power light on front panel is on
1 The gun switch circuit is incomplete.
• Check the gun switch for continuity
with an ohm meter when the switch is
pressed. Replace if faulty
• Check the 2 pin receptacles in the MIG
gun adaptor are making contact with
the mating pins from the gun end.
There is wirefeed but no output
voltage when gun switch is closed:
1 Power source may have overheated.
• The Weldmatic 270C welding power
source incorporates an in-built over-
temperature thermostat which will
trip if the welding load exceeds the
operating duty cycle. The thermostat
will reset automatically - do not switch
