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.
No Welding Current
Check:
1 Check that mains supply is available
at the Weldarc inverter power source.
The display panel lights should be
on. If not, test outlet using a known
working appliance.
2 Check that the welding and work leads
are connected securely to the output
sockets at the front of the machine.
3 Check for continuity of the work lead,
work clamp and electrode holder. Loose
connections can prevent proper flow of
the welding current.
4 The Weldarc inverter welding power
source incorporates an in built protection
device which will operate if the unit is
overloaded. In this event, the machine
will not deliver welding current, and the
Over Temp light will be on. Leave the
machine energised with the fan running
to achieve the maximum cooling rate.
5 If the supply voltage is too high or too
low then the Voltage Range Indicator
light will be on and the machine will not
deliver welding current.
Check the mains voltage supply. Long
extension cords can cause low voltage.
A generator can cause high voltage.
