Weld Output Controls - Miller Trailblazer 302 Diesel Owner's Manual

6-2. Weld Output Controls

1 Process/Contactor Switch
See Section 6-3 for Process/Contactor switch
information.
2 And 3 Displays
Displays can show weld process information
(voltage and amperage) or engine and main-
tenance information.
Meter Weld Functions: In Wire modes, Volt-
meter displays preset weld voltage when not
welding. Meters display actual voltage and
amperage when welding and for five seconds
after welding has stopped.
In Stick and TIG modes, Voltmeter reads ON
and Ammeter displays preset amperage when
the contactor is on and not welding. The Volt-
meter reads 0 (zero) when in remote with the
contactor off. Meters display actual voltage
and amperage when welding and for five sec-
onds after welding has stopped.
Meter Engine And Maintenance Functions:
See inset from maintenance label.

If displays read: HLP_001, and engine does
not return to idle, check throttle solenoid. Turn
Engine Control switch to OFF to reset shut-
down.
4 Voltage/Amperage Control
Use control to select weld voltage or
amperage. Control may be adjusted while
welding.
With Process/Contactor switch in any Stick or
TIG setting, use control to adjust amperage.
With Process/Contactor switch in any Wire
position, use control to adjust voltage. When a
remote voltage/amperage control is con-
nected to Remote receptacle RC4, control
sets the maximum amperage in Stick and TIG
modes, but has no effect in MIG modes.
5 Remote Receptacle
Use receptacle to connect remote control or
wire feeder.

When a remote voltage/amperage control is
connected to the Remote receptacle, the Auto
Sense Remote feature automatically switches
voltage/amperage control to the remote con-
trol (see Sections 5-10 and 6-6).
With remote voltage/amperage control con-
nected, weld output in CC mode is determined
by a combination of front panel and remote
control voltage/amperage settings. In CV
mode, weld output is controlled through re-
mote control only.
If no remote voltage/amperage control is con-
nected to the Remote receptacle, the front
panel Voltage/Amperage control adjusts volt-
age and amperage.
6 DC Polarity/AC Switch
NOTICE − Do not switch while welding.
Use switch to select AC weld output or polarity
of DC weld output.
