When the MIG light (2) is illuminated, the unit is in MIG Welding mode.

SETUP

To enter MIG welding mode, depress the SETUP (6) button once to go to GUN selection. Rotate the right knob (9) to select the gun being used. Select MIG for standard MIG gun, or select XR-A, EDGE, PYTH alpr for push pull guns, or SPL for spoolgun.

Depress SETUP (6) a second time to illuminate the PROCESS (3) light. Rotate right knob (9) until MIG is displayed (for MIG only units NOT USED will be displayed).

Depress SETUP (6) button again to illuminate the WIRE (4) light. This menu is not used in MIG Welding mode.

Depress SETUP (6) button again to illuminate TIMERS (5) light. For description of the TIMERS, refer to TIMERS menu (see Section 5-3)

If crater fill function menus are enabled, TIMERS light will stay on to allow for adjust- ment of crater parameters and timers (see Section 5-6).

Depress SETUP (6) button again to exit menus and enter MIG welding mode.

OPERATION

Adjust welding Voltage with left knob (8) and Wire Feed Speed with right knob (9). Refer to MIG welding chart for proper Voltage and Wire Feed Speed setting in reference to material type, material thickness, wire, and gas (see Section 4-9).

ARC CONTROL

MIG welding mode: Depress ARC CONTROL (7) button to enter Arc control menu and INDU will appear on the left display and the corresponding setting will appear on the right display. Adjust right knob (9) to adjust inductance setting. In MIG welding mode the Arc control is an inductance control from 0-99. Refer to MIG welding chart for suggested Inductance setting for the wire and gas types being used (see Section 4-9). Changing the inductance will change the fluidity of the puddle.

Low Inductance	High Inductance
Weld Bead	Weld Bead
(0 setting)	99 setting
