6-2. Description Of Front Panel Controls (See Section 6-1)

Engine Starting Controls
1 Engine Control Switch
Use switch to start engine, select engine
speed, and stop engine.
In Run position, engine runs at weld/power
speed. In Run/Idle position, engine runs at
idle speed with no generator power or weld
load, and weld/power speed with load ap-
plied.
NOTICE − Diesel engines in Miller equipment
are meant to operate optimally at moderate to
rated load. Using light or no load for extended
periods of time may cause wetstacking or en-
gine damage.
2 Engine Display
See Section 11 for engine display information.
Weld Meters
.
Weld meters also work in combination to
display troubleshooting help codes (see
Section 8-12).
.
The values displayed on meters are for
reference only. The meters are not in-
tended for exact current or voltage mea-
surements.
3 DC Ammeter
Ammeter displays preset amperage (Stick
and TIG only) when not welding, and actual
output amperage when welding.
To set amperage, turn Process/Contactor
switch to Stick or TIG position. Turn V/A con-

trol until desired amperage is displayed on
Ammeter. When welding is finished, ammeter
displays weld amperage and after 5 seconds
defaults to preset amperage.
4 DC Voltmeter
Voltmeter displays preset voltage (MIG weld-
ing) with contactor off, and actual output volt-
age with the contactor on. Voltmeter displays
voltage at the weld output terminals, but not
necessarily the welding arc due to resistance
of cable and connections.
To set voltage, turn Process/Contactor switch
to MIG or FCAW position. Turn V/A control
until desired voltage is displayed on Volt-
meter. When welding is finished, voltmeter
displays weld voltage and after 5 seconds de-
faults to preset voltage.

5 Arc Control
See Section 6-5 for Arc Control information.
6 Voltage/Amperage Control
With Process/Contactor switch in any Stick or
TIG setting, use control to adjust amperage.
With Process/Contactor switch in any Wire
(MIG or FCAW) position, use control to adjust
voltage. Control limits the remote amperage
in Stick or TIG mode, but has no effect in Wire
modes.
7 Process/Contactor Switch
See Section 6-4 for Process/Contactor
switch information.

Engine Control switch is placed in the Run
or Run/Idle position. Glow plugs function
automatically according to ambient tem-
perature. The operator needs to pause at
either switch position while the engine con-
troller goes through the preheat sequence.

See Section 8-11 for overload protection in-
formation.
9 Remote Control Receptacle
Use receptacle to connect remote controls,
wire feeders, and tools requiring 24 VAC.
When a remote control is connected to the
Remote receptacle, the Auto Sense Remote
feature automatically switches voltage/am-
perage control to the remote control (see Sec-
tion 6-9).
With remote control connected, weld output is
determined by a combination of front panel
and remote control voltage/amperage set-
tings.
If no remote control is connected to the Re-
mote receptacle, the front panel Voltage/Am-
perage control adjusts voltage and amper-
age.
.
If a remote device connected to Remote
Receptacle is faulty or is disconnected
during operation, the meters display Help
25 (see Section 8-12). Clear fault by stop-
ping and restarting the unit or by turning
Process/Contactor switch to another
position.
10 Polarity Switch (Optional)
NOTICE − Do not switch under load.
Use switch to change weld output. Select ei-
ther DC Electrode Positive (DCEP) or DC
Electrode Negative (DCEN).
