SECTION 5 − OPERATION

5-1. Operational Terms

The following is a list of terms and their definitions as they apply to the interface unit in the wire feeder:

General Terms:

 

Arc Adjust

Term used to represent arc length adjustments in pulse programs. Increasing Arc Adjust increases

 

the actual arc length. Likewise, decreasing arc adjust shortens arc length. Arc Adjust is replaced by

 

volts in MIG programs.

Trigger Control

Selecting Trigger Control allows activating trigger functions such as DS, TH, 4T, TDS, and TPS.

DS (Dual Schedule)

Dual Schedule allows selecting a pair of programs that can be used together.

TH (Trigger Hold)

Trigger Hold allows the operator to feed wire without continuously pressing the gun trigger. In trigger

 

hold mode, momentarily press gun trigger, and wire will feed until gun trigger is momentarily pressed

 

again.

4T

4T allows the operator to select between weld parameters and crater parameters using the gun

 

trigger. Crater time must be set for at least 0.2 seconds to make this function operational. If gun

 

trigger is released during welding, unit goes into trigger hold, then pressing and holding trigger again

 

causes unit to stay in crater until trigger is released and crater parameter times out.

TDS (Trigger Dual Schedule)

TDS allows the operator to select between a pair of weld programs by using the gun trigger. In TDS

 

mode, momentarily pressing the gun trigger allows the operator to cycle between a pair of preselected

 

weld programs.

TPS (Trigger Program Schedule)

TPS allows the operator to select weld programs by using the gun trigger. In TPS mode, momentarily

 

pressing the gun trigger allows the operator to cycle through preselected weld programs up to a total

 

of 8 programs.

Program

Eight active slots for selection of various processes, wire type, and parameters.

Process

A selection made for MIG, Pulse, Accu-pulse, and RMD (optional).

MIG

CV weld process with individual settings of voltage and wire speed.

Pulse

Conventional pulse program using peak, background, pulse width, frequency, and peak voltage as

 

factory taught data. Adaptive method is controlled by frequency adjustment.

Accu-pulse

Pulse process utilizing constant current ramps with constant voltage control of peaks and

 

backgrounds. Adaptive response is controlled by peak and minimum current levels. Benefits are

 

shorter arc lengths, better puddle control, more tolerant of tip-to-work variation, less audible noise, no

 

arc wandering, allows weld to fill in at toes increasing travel speed and deposition, and more tolerant

 

to poor fit up and gaps.

Accuspeed

CV Pulse process designed for high travel speeds. Typically used in Robotic applications. Arc is de-

 

signed to be tight and fast. Front panel display is ACCU − SPED.

AccuCurve

CV Pulse process using a pulse waveform with modified curves at particular locations within the wa-

 

veform. Has a distinguished change in arc characteristics. Front panel display is ACCU − CURV.

RMD (optional)

RMD refers to Regulated Metal Deposition. A precisely controlled short-circuit transfer. Benefits of

 

RMD are well suited to thin materials, improves gap filling and spatter reduction. Provides less heat

 

input into workpiece, minimizes distortion and allows use of larger diameter wire on thin gauge

 

materials.

Wire Type

Selection of wire type by alloys and classification.

Gas Type

Selection of shielding gas being used in application.

Process Set Up

Selection procedure for entering program.

Program Load

Enters selected program information into program slot.

Volts

Preset voltage in MIG mode at idle, actual voltage while welding, and 3 seconds hold value at end of

 

weld.

Time

Indicates time values being set for timed functions (e.g. Preflow, Postflow which are only available in

 

the Arc On and Analog input or the Arc On and No Analog input modes).

Arc Length

Distance from end of wire electrode to workpiece.

WFS

Term used to represent wire feed speed. In MIG mode, wire feed setting is independent of voltage

 

setting. In pulse, Accu-pulse, and RMD (optional) adjusting wire feed speed also increases power

 

level on wire electrode (one knob control).

Amps

Indicates average amperage while welding and 3 seconds hold value at end of weld.

Arc Control

Allows setting of inductance in MIG mode. In pulse and Accu-pulse mode, this adjustment changes

 

the arc cone by adjusting the preprogrammed factory pulse data. In RMD (optional), this control will

 

affect the in much the same way as inductance.

Inductance

In short circuit GMAW welding, an increase in inductance will decrease the number of short circuit

 

transfers per second (provided no other changes are made) and increase the arc-on time. The

 

increased arc-on time makes the welding puddle more fluid.

Adjust

Control knob used to change or set parameters and functions.
