Voltmeter And Wire Feed Speed Meter Operation

1 Voltmeter
2 Wire Feed Speed Meter
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
6-3.

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 welding. Jog wire feed speed for the spool gun and push/pull gun is limited to 300 ipm (7.6 m/min).

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 weld-
ing arc extinguished, the voltmeter displays
the last actual voltage for 5 seconds and
then returns to preset voltage. If welding re-
sumes 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
2
The wire feed speed meter will display pre-
set wire feed speed (IPM) for the appropri-
ate 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.
