Trigger Interlock
Trigger Interlock operation provides for operator
comfort when making long welds. When the gun
trigger is first pulled, the welding power source
energizes the output and the wire feeder feeds
wire for welding. The gun trigger is then released
while the weld is made. To stop welding, the gun
triggerispulledagain,andwhenitisreleasedthe

feederstopsfeedingwire.
If the arc goes out while welding with
trigger interlock operation, the elec-
trode output from the welding power
source remains energized and the wire
feeder will continue to feed wire until
the gun trigger is again pulled and
then released.
