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 amperage as detailed in
specifications.
4. Make sure Voltage Switch matches voltage being
used.
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.
1. Increase amperage.
2. Reposition clamp on bare metal.
3. Wait for fan to stop and follow suggested duty cycle.
4. Ensure both ground wire and Stick/TIG wire are
