2. Circuit breaker, 7 A
Circuit breaker, 7 A
This resettable 7 A circuit breaker, in series with motor armature, protects the control board
from damage if the motor is stalled.
Jog/Purge switch
JOG is used when you need to feed the wire without welding voltage being applied. The wire
is fed at the set speed for as long as the switch is pushed.
PURGE is used when measuring the gas flow or to flush any air or moisture from the gas
hoses before welding starts. The gas flows as long as the switch is pushed. There is no need
for welding voltage or wire feed start.
If the wire has been threaded through the torch and contact tip, simply operate the jog button
or cut off wire, as required, so that the wire extends about 1/2" beyond the end of the torch
nozzle.
CC/CV switch
The CC/CV switch is used to set CC or CV mode. CC mode is used for constant current
power sources. CV mode is used for constant voltage power sources. The selected mode
also affects the functions of the wire feeder as shown below:
