(See "Installation Section" for function.)
2. COLD FEED / GAS PURGE SWITCH
Place the rocker (momentary) switch in the FOR-
WARD position for cold feeding, or in the REAR
position for gas purge.
When cold feeding, the wire drive will feed elec-
trode but neither the feedplate nor the gas solenoid
will be energized. Adjust the speed of cold feeding
by rotating the WFS knob. Cold feeding, or "cold
inching" the electrode is useful for threading the
e l e c t r o d e
through the
gun.

OPERATION
(See Figure B.2)
DESCRIPTION
FIGURE B.2
1
When gas purging the gas solenoid valve will
energize but neither the power source output nor
the drive motor will be turned on. The Gas Purge
switch is useful for setting the proper flow rate of
shielding gas.
3. 2-STEP/ TRIGGER INTERLOCK
SWITCH
The 2-Step/Trigger Interlock switch changes the
function of the gun trigger. 2-Step trigger operation
turns welding on and off in direct response to the
trigger. Trigger Interlock operation allows welding to
continue when the trigger is released for comfort on
long welds.
Place the rocker 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.
