4-1. Operational Terms

NOTE

See Menu Guide for detailed programming steps.

The following is a list of terms and their definitions as they apply to this wire feeder:

General Terms:
Adaptive Pulse Welding	The wire feeder automatically regulates pulse frequency to maintain a constant arc length, regardless
	of change in welding wire stickout.
Cold Wire Jog	When weld amperage is not present, wire feeds for about three seconds at set wire feed speed. Then
	the welding power source contactor deenergizes and wire continues to feed at the wire jog speed.
Inductance	As inductance increases, arc on time increases, and the weld puddle becomes more fluid.
Trim	Arc length adjustment in pulse welding. Increasing trim increases the actual arc length. Trim is re-
	placed by volts in MIG programs.
Synergic	The operator programs pulse parameters for a specific wire feed speed. The wire feeder determines
	the pulse parameters between these wire feed speed increments.
Side Panel Terms:
Card Mode	Is used to select use of the optional data card storage and retrieval capabilities.
Dual Schedule Mode	Is used to select a pair of programs that can be used together.
Process Mode	Is used to select the type of process to be used, including Pulse, Adaptive Pulse, or Mig.
Sequence Mode	Is used to select and program the weld sequences which include weld, crater, burnback, postflow,
	preflow, and run-in.

1 Apk = Peak Amperage

Increasing Apk increases penetra- tion.

2Abk = Background Amperage Maintains arc between pulses.

3PPS = Pulses Per Second

Increasing PPS increases travel speed.

4PWms = Pulse Width In Milliseconds

Increasing PWms increases bead width.
