5-2. 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
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).
