WARNING
If the arc goes out while welding with trigger interlock
operation, the electrode 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.
2. CV/CC switch
The CV/CC switch sets the wire feed
speed control method for the wire
feeder.
In the CV position, the wire feed speed
remains constant during welding. A
steady arc voltage is regulated by the
power source by adjusting the arc
current.
In the CC position, the wire feed speed varies during
welding. The arc length is maintained by changing the
wire feed speed.
3. Pressure arm and adjustment
(See installation section)
4. Optional timer kit
The optional Timer Kit provides control of preflow time,
burnback, and postflow time.
5. Spool retainer
To release the spool retainer, squeeze the metal bar
inwards. When securing the spool, verify the spool
retainer is fully seated in place in one of the three
grooves of the spindle.
6. Spool brake
Adjust the spool brake to provide enough friction to stop
wire overrun. Excessive brake force may cause motor
thermal overloads or welding problems.
7. Gun bushing, thumb screw and socket head cap
screw
(SEE INSTALLATION SECTION)
8. Drive rolls and wire guides
(See installation section)
9. Cold feed pushbutton
When cold feeding, the wire drive will feed electrode but
neither the power source 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 electrode through
the gun.
Rear controls:
(See Figure 13)
1. Gas purge pushbutton
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. Flow meters should always be
adjusted while the shielding gas is flowing.
