There is wirefeed but no output
voltage when gun switch is closed:
1 Power source may have overheated.
• The Weldmatic Fabricator 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 the equipment off as
the cooling fan will assist the resetting
of the thermostat
• If problem persists after the cool
down period, call your WIA service
agent.

started, or during weld
