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. See "Installing
The Welding Wire", page 14.
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 gun.
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 machine is plugged in.
Check the status of your INPUT VOLTAGE
INDICATOR LED (2). It should be
illuminated. Check the voltage of your
outlet. If it is 10% more or less than 120V,
call a qualified electrician.
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.
