PIPEFAB™ WELDING SYSTEM
MIG HOME SCREEN
FIGURE B.11
1. Feedhead Indicator – Shows which side of the wire feeder is selected and ready for setup. The
ac�ve side can be selected by pressing the Feedhead Select Switch, Cold Feed Switch, or the gun
trigger for the desired side.
2. Menu Bar - Use the Menu knob to scroll through the op�ons along the bo�om of the screen.
Press the knob to select the highlighted op�on.
3. Wire Feed Speed Se�ng - Sets the desired wire feed speed, use le� knob to adjust.
4. Voltage/Trim Se�ng - Sets the voltage or trim, use right knob to adjust.
5. MIG Mode Selec�on.
6. Wire Type Selec�on.
7. Wire Diameter Selec�on.
8. Gas Type Selec�on.
9. 2-Step/4-Step Trigger Interlock - Toggles between 2-Step and 4-Step Trigger Interlock. 2-Step
provides weld power and feeds wire only when the trigger is depressed. 4-Step eliminates the
need to hold the trigger while welding. It operates in 4 steps:
1.
2.
3.
4.
NOTE: No symbol will be shown if 2-Step mode is ac�ve.
10. Ul�marc/Pinch – Ul�marc and Pinch regulate the focus or shape of the arc. Values greater than
0.0 increase the pulse frequency while decreasing the background current, resul�ng in a �ght,
s�ff arc best for high speed sheet metal welding. Values less than 0.0 decrease the pulse
frequency while increasing the background current, for a so� arc good for out-of-posi�on
welding. The MIG mode will determine if Ul�marc is used or Pinch.
11. Synergic Voltage Indicator – Nominal voltage is shown. Lowering the voltage below nominal will
move the bar to the le�. Raising the voltage above nominal will move the bar to the right.
Close trigger and establish welding arc.
Release trigger and con�nue welding.
Reclose trigger near end of weld.
Release trigger again to stop welding.
