Wire pushes gun back from the
workpiece.
Gun held too far from the workpiece.
Hold the gun at the right distance.
Poor quality welds.
Rusty, painted, oily or greasy workpiece.
Ensure workpiece is clean and dry.
Rusty or dirty wire.
Ensure wire is clean and dry.
Poor ground or gun contact.
Check ground clamp/workpiece
connection and all connections to the
machine.
Weld deposit “stringy” and
incomplete.
Gun moved over workpiece too quickly.
Move the gun slower.
Weld deposit too thick.
Gun moved over workpiece too slowly.
Move the gun faster.
Welding voltage/amperage too low.
Increase welding voltage/amperage.
Neither INDICATOR LED is
illuminated and nothing works
on the welder.
Machine is not turned ON.
Turn machine ON with ON/OFF SWITCH.
No input power present.
Make sure machine is plugged in.
Verify that circuit breaker has not been
tripped. Reset if needed.
Verify output power from the outlet.
Both INDICATOR LEDS are
illuminated and there is no
output power from the welder.
Exceeded duty cycle; thermal protector
engaged.
Allow welder to cool at least 10 minutes
with machine ON (observe and maintain
proper duty cycle). FAULT/THERMAL
OVERLOAD INDICATOR LED (3) should
turn off after the machine has cooled.
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.
Incorrect voltage supplied to welder.
Check the voltage of your outlet. If it
is 10% more or less than 120V, call a
qualified electrician.
