Power Up Status

Both meters display zeros at unit power up. After one second, preset values appear on both meters. The MIG gun settings (not spool gun) are always the default at initial power up of the unit.

Welding Status

When either a MIG gun or spool gun trigger is pressed and a welding arc is established, the voltmeter displays actual weld voltage. When the gun trigger is released and welding arc extinguished, the voltmeter displays the last actual voltage for 5 seconds and then returns to preset voltage. If welding resumes before unit displays preset voltage, actual welding voltage will appear on the voltmeter.

The wire feed speed meter always displays preset wire feed speed (IPM).

Gun Selection

The wire feed speed meter will display preset wire feed speed (IPM) for the appropriate gun selection either MIG or spool gun. To preset desired wire feed speed, connect desired gun, press gun trigger for one second, and release trigger. The meter preset will be retained by the meter board until a different gun is connected and preset is performed or the unit is turned off and back on. The MIG gun settings (not spool gun) are always the default at initial power up of the unit.

Error Message

If the rectifier thermostat opens, the voltmeter will display (H – –) and the wire feed speed meter will display (– – –). During this overheated condition, the unit is inoperative and the meters retain their display until the rectifier returns to normal operating temperature.
