CHECKS
• Make sure that the power re-
quired by the welding process is
lower than the maximum rated
power output.
• Check that the operating condi-
tions are in compliance with the
welding power source data plate
specifications.
• Check for the presence of ad-
equate air circulation around the
welding power source.
• Check that the connecting cable
between power source and wire
feeder is intact and make sure
the connectors are securely
tightened.
• Check the data transmission
wiring inside the power source
and the wire feeder.
• Check for correct operation of
the control board in the power
source and the Motor Board in
the wire feeder.
• Make sure the torch trigger is
not pressed, jammed, or short
circuiting.
• Make sure the torch and MIG/
MAG torch connector are intact.
• Check that the connection to the
cooler is correct.
• Check that the O/I switch is set
to I and that it illuminates when
the pump is running.
• Check that the cooler is filled
with coolant.
• Check that the cooling circuit is
intact, notably the torch hoses
and the internal connections of
the cooler.
• Check that the programmed arc
voltage value is not too high in
relation to the thickness of the
work to be welded.
