Likely Solutions
1. Stop welding and wait about 8-10 minutes
with the Power Switch ON for the welder
to cool. Reduce duration or frequency
of welding periods to help reduce wear
on the welder. Refer to Duty Cycle
(Duration of Use) on page 17.
2. Qualified technician must check
and secure/replace Trigger.
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.
3. Verify that the circuit is designed to supply
the required input voltage and amperage
as detailed on the Specifications table.
4. Make sure installed plug is correct
rating (250 VAC, 50A recommended)
- see Specifications on page 7.
1. Make certain that the workpiece is
contacted properly by the Ground
Clamp and that the workpiece is
properly cleaned near the ground
clamp and the welding location.
2. Verify that Contact Tip is the proper
size for welding wire. If needed, replace
Contact Tip with proper size and type.
3. Check that the hole in the tip is not
deformed or enlarged. If needed, replace
Contact Tip with proper size and type.
4. Properly clean Contact Tip.
