1. Tripped thermal protection
device (Error code:F01).
2. Faulty or improperly connected
Trigger.
3. Ground Clamp not attached to
workpiece.
4. Shielding Gas not connected.
1. Reduce duration or frequency of welding
periods to help reduce wear on the welder.
2. Qualified technician must check and
secure/replace Trigger.
3. Attach Ground Clamp to workpiece.
4. Connect shielding gas to Welder.
PROBLEM POSSIBLE CAUSES LIKELY SOLUTIONS
Welder Does Not
Function When
Switched On
1. Unit is not connected to outlet
properly.
2. Outlet is unpowered.
1. Verify the voltage at the outlet and the
connection to the outlet.
2. Check circuit breaker/GFCI devices; if any are
tripped, determine and remedy cause before
resetting. Verify that the circuit is designed
to supply the required input amperage as
detailed in Specifications on page 7.
Power ON
Indicator does not
light when
switched on
1. Incorrect line voltage.
2. Improper gauge or length of cord.
1. Loose electrode cable or ground
cable.
2. Damaged electrode holder or
loose connection within electrode
holder.
3. Adjust current setting.
4. Shielding gas getting low.
1. Check the line voltage and, if insufficient, have
a licensed electrician remedy the situation.
2. Do not use an extension cord on this Welder.
Use only the supplied power cord for this
Welder or an identical replacement cord.
1. Check to ensure that all connections are
tight.
2. Have a qualified technician inspect and
repair/replace as necessary.
3. Make sure setting matches recommended
setting on chart.
4. Replace shielding gas cylinder.

TROUBLESHOOTING – TIG / STICK WELDING
IMPORTANT!
Be CERTAIN to shut off the Welder, disconnect it from power, and discharge the electrode to ground before
adjusting, cleaning, or repairing the unit.
ALARM INDICATOR ERROR CODES
Follow all safety precautions whenever diagnosing or servicing the equipment.
1. Welder has overheated. Duty Cycle
was likely exceeded.
2. Input voltage for welder is too high.
3. Input voltage for welder is too low.
1. Reduce duration or frequency of welding
periods to help reduce wear on the welder.
2. Decrease the input voltage to 120 V.
3. Increase the input voltage to 120 V.

Faulty or improperly connected Trigger.
Ensure the gun connection is properly seated on
machine. Qualified technician must check and
secure/replace Trigger.
Electrode has shorted against workpiece,
no arc is detected. The electrode is stuck
against the workpiece, allowing all current
to go directly through without welding.
Free the electrode from the plate.
