12Weld Functions/Setup Indicator Lights

VOLTS illuminates in MIG welding mode indicating volts in left display can be adjusted. Also, VOLTS lights to indicate left display is showing actual voltage during welding and for 5 seconds after the arc is extinguished.

ARC LENGTH illuminates in Pulse MIG welding mode indicating Arc Length can be adjusted.

SETUP illuminates when a parameter on the corresponding display above the light can be adjusted.

WIRE SPEED illuminates in either Pulse MIG or MIG welding mode indicating wire speed can be adjusted.

AMPS illuminates indicating welding amps appears in the display, instead of wire speed, during welding and for 5 seconds after the arc is extinguished.

.The first time the welding power source is energized it starts in MIG welding mode. Each time after the initial startup, when the unit is turned off, whatever mode and parameter settings were last set will remain as the current settings the next time the unit is energized.

4-2. MIG Mode

In MIG mode, VOLTS is lit under left display and WIRE SPEED is lit under right display. Left knob is used to adjust welding voltage within a range of 14-32 volts, and right knob is used to adjust wire feed speed within a range of 25-700 IPM. Refer to weld chart in front compartment for proper parameter settings according to wire type, shielding gas, and material type and thickness.

4-3. Jog Mode

If gun trigger is pressed and held for more than 3 seconds without striking an arc, unit will automatically shut off weld power. For MIG guns, shielding gas will shut off after 1 minute, and for spool guns, shielding gas will continue to flow
