TROUBLESHOOTING GUIDE
POSSIBLE CAUSE
Bad ground or loose ground connection.
Trigger not pulled while wire is in contact
with workpiece.
No pressure on the drive roller; insufficient
or excessive pressure on the drive roller.
Wire spool is empty
Torch trigger is not being pulled or is not
making contact.
Exceeded duty cycle; thermal protector
engaged.
Insufficient air flow causing machine to
overheat before reaching duty cycle
NO voltage or incorrect voltage supplied to
welder.
ON/OFF SWITCH is in the OFF position
Circuit breaker has been tripped

POSSIBLE SOLUTION
Check connection of the ground cable to the
ground clamp Tighten cable connection to ground
clamp if needed. Ensure that the connection
between the ground clamp and workpiece is good
and is on clean, bare (not painted or rusted) metal.
Pull the trigger while in contact with the workpiece.
The machine does not arc unless the trigger is
pulled
Adjust the drive pressure.
Check if wire is in place and replace if necessary
Pull the trigger while in contact with the workpiece
The machine does not arc unless the trigger is
pulled Depress the trigger ALL THE WAY until the
trigger stops moving into the torch.
Allow welder to cool at least 10 minutes with
machine ON (observe and maintain proper duty
cycle)
Check for obstructions blocking air flow and
ensure that there are 12 inches of clearance
between any obstacles and the vents on all sides
of the machine.
Make sure the INPUT VOLTAGE is 1IOV and
make sure the machine is plugged in
Turn the ON/OFF SWITCH to the ON position
Make sure the circuit breaker has been reset. DO
not use the machine on a GFI outlet.
