SECTION 4 − OPERATION
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 |

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.
