5-2. Voltmeter And Wire Feed Speed Meter Operation

Power Up Status

Both meters display 888 at unit power up. After 0.5 seconds, preset values appear on both meters. The settings for the last active gun used will be the default at initial power up of the unit. If the power is reset to quickly, characters other than 888 may appear. To reset, turn power off for at least 3 seconds, then turn power back on.

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, Spool or Push/Pull 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 settings for the last active gun used will be the default at initial power up of the unit.

5-3. Jog Mode

If the trigger on either gun is held for more than 3 seconds without striking an arc, the unit will automatically shut off weld power (and shielding gas output on MIG or push/pull gun), but will feed wire continuously at the preset wire feed speed (which may be faster or slower than Run−in Speed) until trigger is released. Jog wire feed speed is the same as weld wire feed speed, so any time jog speed is changed, be sure to change back to weld wire feed speed before weld- ing. Jog wire feed speed for the spool gun and push/pull gun is limited to 300 ipm (7.6 m/min).
