(A) WIRE SPEED CONTROL :
This control sets the feed speed of the wire feeder. Turn the knob to the LEFT for slower speeds and
to the RIGHT for higher speeds. This control is calibrated. The nameplate shows the wire speed for the
given setting of the control.
(B) WIRE DIRECTION :
Controls the direction the wire is being fed through the feeder. UP to return wire to the spool. DOWN to
feed the wire to the gun.
( C) PRE-FLOW CONTROL:
This control provides flow of shielding gas to the work before the arc is established. The gas solenoid
valve is energized immediately when the gun trigger is closed, but the time delay before the wire feeder
is energized is adjustable from 0 to 1.5 seconds. Turn the knob LEFT for shorter delays and to the RIGHT
for longer delays.
(D) POST-FLOW CONTROL:
This control provides flow of shielding gas to the work after welding has stopped. Delay for gas solenoid
valve shutoff is adjustable from .5 to 4.5 seconds. Turn the knob to the LEFT for shorter delays and to the
RIGHT for longer delays.
(E) BURN BACK CONTROL:
This control provides a precise time delay that allows the wire to be burned off at the end of the weld. This
is useful for those applications where higher speed, fine wire feeding is used and there is a tendency for
the electrode to overrun at the end of the weld and causes “sticking” in the crater. The delay is adjustable
for optimum burn back depending on the wire size, process, and procedure, etc.
(F) PURGE / COLD INCH CONTROL:
This control provides control of some wire feeder functions without energizing the welding power source.
The momentary up position energizes the gas solenoid but not the wire feeder or welding power source.
The momentary down position energizes the wire feeder but not the gas solenoid or the power source.
(G) ROTATION SPEED DIGITAL DISPLAY:
Visual display that supplies rotation speed information to the operator.
(H) ROTATION SPEED CONTROL:
Controls the speed in which the machine travels. Turn the knob LEFT to decrease the rotation speed and
to the RIGHT to increase the rotation speed. The digital read out displayed should NOT be construed as
inches per minute of travel. They should be considered as reference only.
(J) TRAVEL DIRECTION CONTROL:
Controls the direction in which the machine will travel in the MANUAL MODE. Turn the switch to the
RIGHT for clockwise rotation, CENTER to stop and to the LEFT for counter-clockwise rotation. When
in the AUTOMATIC MODE, set to the CENTER (Stop) position. The machine is stationary until the
CYCLE START button (L) is pressed. Once activated, the machine is programmed to weld in the counter-
clockwise rotation.
(K) OVERLAP CONTROL:
Controls the overlap time at the end of each cycled weld. Overlap length is determined by a combination
of time and speed.
