Procedure Change Method
This option selects how remote procedure selection (A/B) will be made. For
some products the selected procedure can be changed locally at the user
interface by pressing the 'A-Gun-B' button. Other products do not have this
button and must use a Cross-switch gun or wire into the procedure
select input. The following methods can be used to remotely change the
selected procedure:
External Switch = Dual 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:
Select "GUN" on the memory panel (for products that have an 'A-Gun-B'
button).
Start the weld by pulling the gun trigger. The system will weld with
procedure A settings.
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 welding. The system will automatically return to
procedure A settings.
IntegralTrigProc = When using a Magnum DS dual-schedule gun (or similar)
that incorporates 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
exclusively 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).

Offset
Adjustment
This option adjusts the wire feed speed calibration of the pull motor of a push-
pull gun. This should only be performed when other possible corrections do not
solve any push-pull feeding problems. An rpm meter is required to perform the
pull gun motor offset calibration. To perform the calibration procedure do the
following:
1. Release the pressure arm on both the pull and push wire drives.
2. Set the wire feed speed to 200 ipm.
3. Remove wire from the pull wire drive.
4. Hold an rpm meter to the drive roll in the pull gun.
5. Pull the trigger on the push-pull gun.
6. Measure the rpm of the pull motor. The rpm should be between 115 and
125 rpm. If necessary, decrease the calibration setting to slow the pull
motor, or increase the calibration setting to speed up the motor.
The calibration range is -30 to +30, with 0 as the default value.
Note: The range was changed to -90 to +90 for the PF25M in WD software
S28539-3. Default value remains at 0.
On dual-head Power Feed 84 Feeders, a different setting can be used for each
head. The operator will be prompted to select which head to edit before the
setting can be changed.
