Procedure Change Method

 

 

 

 

 

 

 

Selects how remote procedure selection (A/B) will be made. The selected procedure can be

 

 

 

 

 

 

changed locally at the user interface by pressing the 'A-Gun-B' button. The following methods

 

 

 

 

 

 

can be used to remotely change the selected procedure:

 

 

 

 

 

 

 

• Use an external switch wired to the procedure select input.

 

 

 

 

 

 

 

• Quickly releasing and re-pulling the gun trigger.

 

 

 

 

 

 

 

• Using a dual-schedule gun which incorporates a procedure select switch in the trigger mecha-

 

 

 

 

 

 

nism (pulling the trigger more than half way changes the procedure from A to B).

 

 

 

 

 

 

 

The possible values for this parameter are:

 

 

 

 

 

 

 

• External Switch = Procedure selection may only be performed at the memory panel or an

 

 

 

 

 

 

external switch (e.g. K683).

 

 

 

 

 

 

 

• Quick Trigger = The selected procedure can be changed remotely by releasing and re-pulling

 

 

 

 

 

 

the trigger quickly while welding. This feature is disabled in 4-Step trigger mode. The external

 

 

 

 

 

 

procedure switch is disabled. To operate:

 

 

 

 

 

 

 

1. Select "GUN" on the memory panel.

 

 

 

 

 

 

 

2. Start the weld by pulling the gun trigger. The system will weld with procedure A settings.

 

 

 

 

 

 

3. While welding, quickly release then pull the gun trigger once. The system will switch to

 

 

 

 

 

 

procedure B settings. Repeat to switch back to procedure A settings. The procedure can

 

 

 

 

 

 

be changed as many times as needed during the weld. Release the trigger to stop weld-

 

 

 

 

 

 

ing. The system will automatically return to procedure A settings.

 

 

 

 

 

 

 

• Integral TrigProc = When using a Magnum DS dual-schedule gun (or similar) that incorpo-

 

 

 

 

 

 

rates a procedure switch in the gun trigger mechanism. While welding in 2-step, machine

 

 

 

 

 

 

operation is identical to the "External Switch" selection. When welding in 4-step, additional

 

 

 

 

 

 

logic prevents procedure A from being re-selected when the trigger is released at step 2 of the

 

 

 

 

 

 

4-step weld sequence. The machine will always operate in 2-step if a weld is made exclusive-

 

 

 

 

 

 

ly in procedure A, regardless of the 2/4 step switch position (this is intended to simplify tack

 

 

 

 

 

 

welding when using a dual-schedule gun in 4-step).

 

 

 

 

 

 

 

 

 

 

 

 

P.6

Stall Factor Adjustment

 

 

 

 

 

 

 

Allows the adjustment of the stall factor in Push/Pull operation. The stall factor controls the stall

 

 

 

 

 

 

torque of the push motor when using a push-pull gun. The wire feeder is factory-set to not stall

 

 

 

 

 

 

unless there is a large resistance to feeding wire. The stall factor can be reduced to stall more

 

 

 

 

 

 

easily and possibly prevent bird nesting. However, low stall factors can cause motor stalling

 

 

 

 

 

 

during normal welding conditions, which results in the wire burning back to the tip or rapid tack

 

 

 

 

 

 

welds. If you are experiencing bird nests, check for other feeding problems before adjusting the

 

 

 

 

 

 

stall factor. The default value for the stall factor is 75, with a range of 5 to 100.
