Operation with Previous Software Version

B-6	OPERATION	B-6

The operation of the previous Control Box software version (S24004-2) is different than described earlier in this section. The differences are as follows:

•The Memory/Dual Procedure panel is not a valid option.

•The MX (K1542-1) and MSP (K1542-8) are are used in place of the MX2 and MSP2 options.

•Limits cannot be set.

The key difference in the MX/MSP panels, compared to the MX2/MSP2 panels, is the Spot function. In the old software, a 0.1 to 2.5 second Spot function was available on these two panels. No Crater function was available (Crater replaced Spot in the graphics on these two panels).

An upgrade kit is available to change the software from S24004-2 to the latest version of Control Box software. Once the upgrade is done, the Dual Procedure/ Memory panel becomes a valid option, limits can be set, and Spot is replaced by Crater.

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 on the gun side of the Status LED. This switch has no effect in CC modes of operation, such as stick welding.

When using 2 Step Logic:

1.Closing the gun trigger initiates the welding sequence (preflow, run in, etc.).

2.Opening the gun trigger ends the arc begins burn- back, postflow, etc..

When using 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 arc begins burnback, postflow, etc..

When using 4 Step Logic 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 arc begins 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 solenoid valve is energized, but neither the power source nor the drive motor will be energized.
