Troubleshooting
Warning
Most components of the 250WFG welder are not serviceable by the operator and should only be ser-
viced by a qualified repair technician. Unauthorized repairs to these units may result in danger to the
operator and will void the factory warranty. For your safety, please follow all safety precautions found
throughout this manual.
Problem
Nothing happens when the trigger is pulled; no wire
feed, weld output or gas flow. Fan is not operating.
When trigger or foot pedal is engaged, there is no
wire feed, weld output or gas flow but the fan oper-
ates.
Little or no gas flow is evident when the trigger or
foot pedal is engaged. Wire feed, weld output and
fan operate as normal.
No wire feed when the trigger is pulled but the fan
runs, gas flows and there is weld output.

2. Insure correct voltage is applied to the welder
and the plug is correctly wired.

ate properly.

clogged and is sized correctly.
