PROBLEM
POSSIBLE CAUSE
POSSIBLE SOLUTION
Wire feeds but no arc.
Bad ground or loose ground connection.
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.
Trigger not pulled while wire is in contact
with workpiece.
Pull the trigger while in contact with the
workpiece. The machine does not arc unless
the trigger is pulled.
Arc works but not feeding wire.
No pressure on the drive roller; insufficient
or excessive pressure on the drive roller.
Adjust the drive pressure. See “Installing The
Welding Wire”, page 14.
Wire spool is empty.
Check if wire is in place and replace if
necessary.
No arc or wire feed. Fan
operates normally (can be
heard).
Gun trigger is not being pulled or is not
making contact.
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 gun.
Exceeded duty cycle; thermal protector
engaged.
Allow welder to cool at least 10 minutes with
machine ON (observe and maintain proper
duty cycle).
Insufficient air flow causing machine to
overheat before reaching 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.
No arc or wire feed. Fan
does NOT operate (cannot be
heard).
No voltage or incorrect voltage supplied
to welder.
Make sure the machine is plugged in.
Check the status of your INPUT VOLTAGE
INDICATOR LED. It should be illuminated.
Check the voltage of your outlet. If it is
10% more or less than optimal, call a
qualified electrician.
ON/OFF SWITCH is in the OFF position.
Turn the ON/OFF SWITCH to the ON
position.
Circuit breaker has been tripped.
Make sure the circuit breaker has been
reset.
