5.11 Trigger Lock Switch S2
The Torch lock switch reduces operator fatigue by allowing the operator to start main arc by depressing
the torch switch and then once the arc is created, allows the operator to release the trigger switch and
continue cutting with the torch. To discontinue the arc the operator simply depresses the trigger switch
and releases it.
This is governed by logic on the IC2 chip. The Switch is connected to PCB1 on pins P6-2 and
P6-1. This connects to the trigger lock in switch circuitry on PCB1.
