P.5 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 fol-
lowing methods can be used to remotely change the selected procedure:
LF45 and C300CE:
Quick Trigger = Allows switching between Procedure A and procedure B while welding with 2-stroke
mode. The Cross-switch gun or remote control is required. To operate:
• Select "Procedure A/B" in P.25 to set up parameters for A and B procedures.
• Start the weld by pulling the gun trigger. The system will weld with procedure A settings.
• While welding, quickly release and then pull the gun trigger. The system will switch to procedure B set-
tings. 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. When the next weld is made, the system will start again with proce-
dure A.
IntegralTrigProc = Allows switching between Procedure A and procedure B while welding with 4-stroke
mode. When in 2-step, the system operates identical to the External Switch selection. To operate in 4-
step:
• Select "Procedure A/B" in P.25 to set up parameters for A and B procedures.
• Start the weld by pulling the gun trigger. The system will weld with procedure A settings.
• While welding, quickly release and then pull the gun trigger. The system will switch to procedure B set-
tings.
• Release the trigger to stop welding. When the next weld is made, the system will start again with proce-
dure A.
External Switch = Dual Procedure selection may only be performed by the Cross-switch gun or remote
control (default).
All Other Products:
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 set-
tings. 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 proce-
dure 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).
