SECTION 10 − OPERATION
10-1. Operational Terms
The following is a list of terms and their definitions as they apply to this interface unit:
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.
AccuCurve CV Pulse process using a pulse waveform with modified curves at particular locations within the
waveform. Has a distinguished change in arc characteristics. Front panel display is ACCU − CURV.
Accu-pulse Pulse process utilizing constant current ramps with constant voltage control of peaks and
backgrounds. Adaptive response is controlled by peak, background, 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.
Adjust Control knob used to change or set parameters and functions.
Amps Indicates average amperage while welding and 3 seconds hold value at end of weld.
Arc Control Allows setting of inductance and slope in MIG mode. In pulse and Accu-pulse mode, this adjustment
changes the arc characteristics by adjusting the preprogrammed factory pulse data.
Arc Length Distance from end of wire electrode to weld pool.
Auto Thread Method of jogging wire without holding jog or trigger switch. By rocking the switch from purge to jog
within 0.5 seconds will automatically feed wire for a factory default setting of 192 in (4877 mm) of wire
before stopping. Default setting is 192 at a feed rate of 700 ipm (these values can be changed using
the HTML pages). Pressing jog, purge, or trigger switch will terminate the auto-threading feature.
Carbon Arc Cutting/Gouging A cutting process by which metals are melted by the heat of an arc using a carbon electrode. Molten
metal is forced away from the cut by compressed air.
Crater Allows setting of voltage/arc adjust, wire feed rate, and time value for arc ends.
DS (Dual Schedule) Dual Schedule allows selecting a program within a pair of programs by means of a dual schedule
switch.
Feeder Set Up Allow selection of Sequence and trigger functions.
Gas Type Selection of shielding gas being used in application.
IGNR (Ignore) Allows the use of a dual schedule switch between ignore welds and count welds when using Insight
Centerpoint.
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.
MIG CV weld process with individual settings of voltage and wire speed.
MWCI Manual Weld Control Interface. A separate remote user interface dedicated to providing arc data
monitoring near the operator’s location. This interface provides the operator with the ability to start a
new part, join welds, or ignore welds. The MWCI has a display for error read-outs and status LEDs.
Preflow Setting a time value for gas flow prior to arc start.
Postflow Setting a time value for gas flow after arc end.
Process A selection made for MIG, Pulse, and Accu-pulse.
Process Set Up Selection procedure for entering program.
Program Eight active slots for selection of various processes, wire type, and parameters.
Program Load Enters selected program information into program slot.
Pulse Conventional pulse program using peak, background, pulse width, frequency, and peak voltage as
factory taught data. Adaptive method is controlled by frequency adjustment.
Retract Sequence function that allows the wire to move back towards the contact tip when a welding
operation is completed. Setting is both speed (IPM) and time (sec).
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.
Sequence Selecting Sequence will allow setting of preflow, start, crater, and postflow times and parameters.
Slope Slope refers to the shape of a volt-amp curve. Varying the amount of slope in the welding circuit will
change the amount of short-circuit current and rate of response from the welding power source.
Start Provides voltage/arc adjust, wire feed rate, and time value for modified arc starts.
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 release and close the gun trigger while welding to cycle between a pair of
preselected weld programs.
