5. THERMAL LED, MOTOR OVERLOAD
The thermal light illuminates when the
wire drive motor draws too much current.
If the thermal light illuminates, the wire
drive will automatically shutdown for up to
30 seconds to allow the motor to cool. To
start welding again, release the gun trigger, inspect
the gun cable, liner (and conduit). Clean and make
repairs as necessary. Start welding again when the
problem has been safely resolved.
For best results, keep the gun cable and conduit as
straight as possible. Perform regular maintenance
and cleaning on the gun liner, conduit and gun.
Always use quality electrode, such as L-50 or L-56
from Lincoln Electric.
6. POLARITY LED
The Polarity LED
lights when the wire
feeder is connected
for positive polarity.
Use the polarity
LED to verify the
wire feeder is connected for the proper polarity.
