because gas valve is located inside spool gun. For MIG guns, wire will feed for up to 2 minutes while trigger is pressed, then wire drive system in unit will automatically shut off. For spool guns, wire will feed for up to 30 seconds before shutting off. If gun trigger is pressed for 3 seconds without striking an arc the displays will show JOG MODE.

4-4. Weld Status

When trigger is released on a MIG gun, spool gun, or push-pull gun, the last actual amperage and voltage will be shown on the displays for 5 seconds. The VOLTS and AMPS indicator lights will illuminate under the displays and each value will appear in the corresponding display.

If a programmed value requires adjustment after the arc is extinguished and during the 5 seconds display of actual values, turning either knob will cause actual values in the displays to be replaced by programmed values for adjustment purposes.

.The 5 second delay after the arc is extinguished for displaying actual weld values can be turned on or off in the Timer menu DISP selection (see Section 5-3).

4-5. MIG Gun-On-Demand

The guns that can be used with this unit are MIG guns, spool guns, and push-pull guns. To switch from one gun to another, momentarily press the trigger on the desired unused gun to make it the active gun. Once the trigger is pressed, the unit will recall stored data and both displays will show the last programmed values for that particular gun. If the unit is powered down and back on again, the gun last used will become the current active gun.

4-6. Pulse MIG Mode Voltage Adjustment

In Pulse MIG mode there is no manual voltage adjustment; instead, voltage is synergically aligned with the proper wire feed speed. Arc Length adjustment is used to adjust actual arc length which automatically adjusts the voltage. See weld chart in front compartment for proper wire feed speed adjustment according to wire size and type.

4-7. Pulse MIG Gun-On-Demand

The spool gun functions slightly different in Pulse MIG mode. To switch from one gun to another, momentarily press the trigger on the desired unused gun to make it the active gun. Once the trigger is pressed, the unit will recall stored data and both displays will show the last programmed values for that particular gun. For a spool gun, the wire speed is taken from the position of the gun potentiometer. This wire speed value is automatically adjusted if the potentiometer is moved since the last time the gun was active. If the unit is powered down and back on again, the gun last used will become the current active gun.

4-8. Tip Saver

If gun contact tip is directly shorted to the workpiece while gun trigger is pressed, the welding arc automatically shuts off after 1 second to prevent wire burnback in the contact tip.
