SECTION 6 − OPERATION
6-1. Operational Terms
The following is a list of terms and their definitions as they apply to this interface unit:
General Terms:
Arc Length
Distance from end of wire electrode to workpiece.
Crater Provides voltage/arc length, wire feed speed and time values for modified arc end.
Dual Schedule Allows selecting a pair of weld parameter settings that can be used together.
Gun Calibration Gun calibration routine allows the welding machine to learn the physical characteristics of the gun and adjust its
operation to provide the most ideal feeding scenario.
Hot Start Provides more power at the beginning of the weld to eliminate incomplete fusion and increase penetration.
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.
Jog Method for feeding wire without contactor or gas valve being energized.
MIG (Gas Metal Arc
Welding)
CV weld process with individual settings of voltage and wire speed.
Postflow The amount of time that the shielding gas will flow after the arc has been shut off.
Preflow The amount of time that the shielding gas will flow after the trigger is pressed and before the welding arc will be
allowed to be active.
Pulse MIG (GMAW) CC weld process with factory taught data using peak and background current, pulse width and pulses per
second. Adaptive pulse control methods modulate one or more of the taught data parameters to regulate or
maintain a fixed arc length.
Purge Method for energizing the gas valve to purge gas lines before welding and to preset gas pressure at the
regulator.
Run-In Allows setting a welding wire feed speed before arc initiation. After arc initiation, the wire feed speed is
controlled by the Wire Speed control setting.
SharpArc In pulse, this adjustment changes the arc cone by adjusting the preprogrammed factory pulse data. In MIG, this
adjustment changes inductance.
Synergic Refers to the system’s ability to match the power setting to the set wire feed speed using a single knob control.
In synergic Pulsed MIG, the pulse parameters are automatically increased or decreased to match the power
output to the set wire speed.
Synergic MIG (GMAW) Synergic refers to the unit’s ability to use preprogrammed pulse parameters to determine the actual pulse
settings of Peak Amperage, Background Amperage, Pulse Frequency and Pulse Width at any specific wire feed
speed setting.
Trigger Hold This feature reduces welder fatigue by allowing continuous welding without holding the trigger.
