SECTION 4 − OPERATION
4-1. Operational Terms
The following is a list of terms and their definitions as they apply to this interface unit:
General Terms: |
|
Synergic | 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. |
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. |
Program | Eight active slots for selection of various processes, wire types, and parameters. |
Process | A selection made for MIG, Pulse, |
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. |
| 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 |
| 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 designed 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 waveform. Has |
| a distinguished change in arc characteristics. Front panel display is ACCU − CURV. |
RMD (optional) | RMD refers to Regulated Metal Deposition. A precisely controlled |
| 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 (process, wire type, gas, etc.) 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, |
| (one knob control). |
Amps | Indicates average amperage while welding and 3 seconds hold value at end of weld. |
Arc Control | Pressing this button will allow setting of inductance in MIG mode and sharp arc in pulse, |
| (optional). |
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 |
| the welding puddle more fluid. |
Sharp Arc | In pulse and |
| pulse data. In RMD (optional) this control will affect the arc in much the same way as inductance. |
Adjust | Control knob used to change or set parameters and functions. |
Sequence | Selecting Sequence will allow setting of preflow, start, crater, postflow, and retract times and parameters (only |
| available on Auto Axcess models in the Arc On and Analog input or the Arc On and No Analog input modes). |
Preflow | Setting a time value for gas flow prior to arc start (only available on Auto Axcess models in the Arc On and |
| Analog input or the Arc On and No Analog input modes, and can only be set with the optional PDA with File |
| Management software). |
