INTERNAL CONTROLS DESCRIPTION

(See Figure B.2)

2 Step - Trigger Interlock Switch

The 2 Step - Trigger Interlock switch changes the function of the gun trigger. 2 Step trigger opera- tion turns welding on and off in direct response to the trigger. Trigger Interlock operation allows welding to continue when the trig- ger is released for comfort on long welds.

Place the toggle switch in the DOWN position for 2 Step operation or in the UP position for Trigger Interlock operation.

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 feed- ing 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.

COLD FEED PUSHBUTTON

(See Figure B.2)

When cold feeding, the wire drive will feed electrode but neither the power source nor the gas solenoid will be ener- gized. Adjust the speed of cold feeding by rotating the WFS knob. Cold feeding, or "cold inching" the electrode is useful for threading the electrode through the gun.
