Run-In Speed Control
This control sets the wirefeed speed that
applies between the time the Start button is
pressed and an arc is established. After arc
initiation, the wirefeed speed is set by the
front panel wire speed control. The Run-In
Speed control acts independently of the
other speed control and therefore can be
set above or below the value set by the other
control.

Burnback Control
This 0 to 1.0 second adjustable control al-
lows setting of the time the wire remains
electrically energized after the drive motor
stops. The Burnback timer starts after the
Stop button is pressed. By adjusting the
control properly, the wire neither freezes in
the weld puddle nor in the contact tube of
the gun. If the wire freezes in the puddle, in-
crease the burnback time. If the wire
freezes in the contact tube, decrease the
burnback time.
