WIRE DRIVE OPERATION

The most frequently used Wire Drive settings are
external; some features are accessed by internal set-
tings.
WIRE DRIVE SETTINGS -- EXTERNAL
2 STEP/4 STEP SWITCH:
The Wire Drive has a 2 Step/ 4 Step switch located
near the gun connector. This switch has no effect in
CC modes of operation, such as stick welding.
Europe and World 2 Step Logic:
1. Closing the gun trigger initiates the welding
sequence (preflow, run in, etc.).
2. Opening the gun trigger ends the welding
sequence (burnback, postflow, etc.).
World 4 Step Logic:
With Crater Fill "OFF"
1. Closing the gun trigger initiates the welding
sequence (preflow, run in, etc.).
2. Opening the trigger after the welding arc is estab-
lished allows the weld to continue as long as cur-
rent flows. If the arc goes out, the 4 step cycle is
reset.
3. Closing the trigger again allows the weld to contin-
ue.
4. Opening the trigger again ends the welding
sequence (burnback, postflow, etc.).
With Crater Fill "ON"
1. Closing the gun trigger initiates the welding
sequence (preflow, run in, etc.).
2. Opening the trigger after the welding arc is estab-
lished allows the weld to continue as long as cur-
rent flows. If the arc goes out, the 4 step cycle is
reset.
3. Closing the trigger again changes the wire feed
speed and the Volts/Trim to the
and the weld to continues
4. Opening the trigger again ends the welding
sequence (burnback, postflow, etc.).
OPERATION
European Only 4 Step Logic
With Crater Fill "OFF":
1. Closing the gun trigger initiates the welding
sequence (preflow, run in, etc.).
2. Opening the trigger allows the wire to continue
feeding before or after the welding
lished. If the arc goes out the wire continues feed-
ing.
3. Closing the trigger again cancels the interlock and
the wire to continues feeding.
4. Opening the trigger again ends the welding
sequence (burnback, postflow, etc.).
With Crater Fill "ON":
1. Closing the gun trigger initiates the welding
sequence (preflow, run in, etc.).
2. Opening the trigger allows the wire to continue
feeding before or after the welding arc is estab-
lished. If the arc goes out the wire continues feed-
ing.
3. Closing the trigger again cancels the interlock
changes the wire feed speed and the Volts/Trim to
the Crater values, and the wire continues feeding.
4. Opening the trigger again ends the welding
sequence (burnback, postflow, etc.).
COLD FEED / GAS PURGE SWITCH:
The Wire Drive has a Cold Feed/Gas Purge Switch
located near the gun connector. This is an up/down
center-off momentary toggle switch.
When held in the up position, the Wire Drive will feed
wire, but neither the power source nor the gas sole-
noid will be energized. When cold feeding, the feed
speed can be adjusted by rotating the WFS encoder
knob on the Control Box. Adjusting the cold feed will
not affect the run in or welding wire feed speed.
When the cold feed switch is released, the cold feed
value is saved.
When this switch is held in the down position, the gas
Crater values,
solenoid valve is energized, but neither the power
source nor the drive motor will be energized.
