CV/CC SWITCH
(See Figure B.2)
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 chang- ing the wire feed speed.

COLD FEED PUSHBUTTON
(See Figure B.2)
When cold feeding, the wire drive will feed electrode but nei- ther the power source nor the gas solenoid will be energized. Adjust the speed of cold feed- ing by rotating the WFS knob. Cold feeding, or "cold inching" the electrode is useful for threading the electrode through the gun.
