PROBLEM
POSSIBLE CAUSE POSSIBLE SOLUTION
Frequent circuit breaker trips.
Machine is drawing too much amperage
due to use of larger size wire.
Use the smallest wire possible for this
welder. 0.030-inch wire is strongly
recommended.
Machine is not the only piece of electrical
equipment on the circuit.
Make sure the welder is on a dedicated
circuit or is the only thing plugged on a
circuit.
Circuit breaker is incorrect/insufficient for
use with this machine.
Verify that the circuit breaker for the circuit
is a 20A time-delay (slow-blow) breaker. If
it is not, have a qualified electrician install
the proper breakers.
Wire pushes gun back from the
workpiece.
Gun held too far from the workpiece. Hold the gun at the right distance.
Poor quality welds.
Insufficient gas at weld area. Check that the gas is not being blown
away by drafts and, if so, move to a more
sheltered weld area. If not, check gas
cylinder contents, gauge, regulator setting,
and operation of gas valve.
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 including the MIG ELECTRODE
POLARITY JUMPER (9) connection.
Incorrect gas/wire combination. Check “Gas Selection”, page 19, and
Set-Up Charts on welder cabinet cover or
pages 19-21 for the correct combination.
Weld deposit “stringy” and
incomplete.
Gun moved over workpiece too quickly. Move the gun slower.
Gas mixture incorrect. See “Gas Selection”, page 19.
Weld deposit too thick.
Gun moved over workpiece too slowly. Move the gun faster.
Welding voltage/amperage too low. Increase welding voltage/amperage.
Difficult arc start (TIG/STICK).
Amperage is too low. Increase amperage setting.
Arc is wandering (TIG).
Tungsten is too large. Use a smaller tungsten.
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.
