2 Step Trigger
2 Step trigger operation is the most common. When the gun trigger is pulled, the welding power source energizes the electrode output and the wire feeder feeds wire for welding. The power source and wire feeder continue welding until the trigger is released.
Trigger Interlock
Trigger Interlock operation provides for operator com- fort 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 trigger is pulled again, and when it is released the welding power source output turns off and the wire feeder stops feeding wire.
CAUTION
•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.
