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 Crater values, and the weld to continues
4.Opening the trigger again ends the welding sequence (burnback, postflow, etc.).
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 arc is estab- 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
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 solenoid valve is energized, but neither the power source nor the drive motor will be energized.
