This welder has been engineered to need minimal service providing that a few very simple steps are taken to properly
maintain it.
1. Replace INPUT POWER CABLE (13), ground cable, ground clamp, or torch/electrode cable when damaged or
worn.
2. Avoid directing grinding particles towards the welder. These conductive particles can build up inside the machine
and cause severe damage.
3. Periodically clean dust, dirt, grease, etc. from your welder. Every six months or as necessary, remove the side
panels from the welder and use compressed air to blow out any dust and dirt that may have accumulated inside
the welder.
WARNING: DISCONNECT FROM POWER SOURCE WHEN CARRYING OUT THIS
OPERATION.
4. Check all cables periodically. They must be in good condition and not cracked.
WARNING: ELECTRIC SHOCK CAN KILL!
Be aware that the ON/OFF SWITCH (12), when OFF,
does not remove power from all internal circuitry in the welder. To reduce the risk of electric shock, always unplug
the welder from its AC power source and wait several minutes for electrical energy to discharge before removing
side panels.
The following is a troubleshooting table provided to help you determine a possible remedy when you are
having a problem with your welder.
This table does not provide all possible solutions, only those considered likely to be common faults.
PROBLEM
POSSIBLE CAUSE
POSSIBLE SOLUTION
All LEDs off, No output power,
Fan not operating.
Machine is not turned ON.
Turn machine ON with ON/OFF SWITCH
(7).
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.
Do not use the machine on a GFI outlet.
DUTY-CYCLE FAULT CODE:
“F01” DISPLAYED ON
AMPERAGE DISPLAY (5) AND
FAULT INDICATOR LED (3) IS
ILLUMINATED
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.
INPUT POWER FAULT CODE:
“F02” DISPLAYED ON
AMPERAGE DISPLAY (5) AND
FAULT INDICATOR LED (3) IS
ILLUMINATED
Incorrect voltage supplied to welder.
Check the voltage of your outlet. If it
is more than 10% above or below the
nominal voltage (120V or 240V), call a
qualified electrician.
OUTPUT SHORT FAULT
CODE: “F09” DISPLAYED ON
AMPERAGE DISPLAY (5) AND
FAULT INDICATOR LED (3) IS
ILLUMINATED
Electrical short is present between the +
and – terminals.
Stick welding electrode is stuck to the
workpiece.
TIG tungsten is shorted to the workpiece.
Separate the electrode or tungsten from
the workpiece.
