Troubleshooting
Intermitting Welder Operation
Welder works properly for a few minutes and then stop operating but returns to full
welding power after several minutes of cooling off.
This will occur when the welder is operated past its duty cycle or in extreme high
ambient temperatures or if welder-cooling circuit is blocked. Be sure air intake is free
welder cooling might be affected by engine heat. Allow fresh air to enter louvered end
cover on welder. A cooling off period is 4-5 times longer if welder is turned off and
sitting still. Running it at its RPM will speed up the cooling and reset the internal
thermal trip.
