ENGINE CONTROLS:
DUAL VANTAGE ® 700 (AU)
13. RUN/STOP SWITCH
-RUN position energizes the engine prior to start-
ing. STOP position stops the engine. The oil pres-
sure interlock switch prevents battery drain if the
switch is left in the RUN position and the engine is
not operating.
14. GLOW PLUG PUSH BUTTON
• When pushed activates the glow plugs. Glow plug
should not be activated for more than 20 seconds
continuously.
15. CIRCUIT BREAKER-
For protection of Battery Charging Circuit.
16. ENGINE STOP BUTTON
Shuts down engine.
17. START PUSH BUTTON
Energizes the starter motor to crank the engine.
18. IDLER SWITCH
- Has two positions as follows:
1) In the HIGH position, the engine runs at the high
idle speed controlled by the engine governor.
2) In the AUTO position, the idler operates as fol-
lows:
• When switched from HIGH to AUTO or after
starting the engine, the engine will operate at full
speed for approximately 12 seconds and then go
to low idle speed.
• When the electrode touches the work or power is
drawn for lights or tools (approximately 100
Watts minimum), the engine accelerates and
operates at full speed.
• When welding ceases or the AC power load is
turned off, a fixed time delay of approximately 12
seconds starts. If the welding or AC power load
is not restarted before the end of the time delay,
the idler reduces the engine speed to low idle
speed.
• The engine will automatically return to high idle
speed when there is welding load or AC power
load reapplied.

19. DASH BOARD GAUGE
The dash board gauge displays 5 gauges:
3a. OIL PRESSURE
The gauge displays the engine oil pressure
when the engine is running.
3b. ENGINE TEMPERATURE
The gauge displays the engine coolant tem-
perature.
3c. HOUR METER
The hour meter displays the total time that
the engine has been running. This meter is a
useful indicator for scheduling preventive
maintenance.
3d. FUEL LEVEL
Displays the level of diesel fuel in the fuel tank.
The operator must watch the fuel level closely
to prevent running out of fuel and possibly
having to bleed the system.
3e. BATTERY VOLTAGE INDICATOR
Displays the battery voltage and indicates that
the charging system is functioning properly.
20. ENGINE PROTECTION LIGHT
A warning indicator light for Low Oil Pressure and/or
Coolant Over Temperature. The light is off when the
systems are functioning properly. The light will come
on and the engine will shutdown when there is Low
Oil Pressure and/or the Coolant is Over Temperature.
Note: The light remains off when the RUN-STOP
switch is in the "ON" position prior to starting the
engine. However if the engine is not started within 60
seconds the light will come on. When this happens the
RUN-STOP switch must be returned to the "OFF" posi-
tion to reset the engine protection system and light.
21. BATTERY DISCONNECT SWITCH
Battery disconnect switch provides lockout/tagout
capability. Switch is conveniently located on the
front bottom of the machine.
22. THERMAL LIGHTS
indicate the Power Source has been driven into
thermal overload. Welding output shuts off to pro-
tect the welding system components and resets
when the overload condition is resolved. The
Engine will continue to operate.
23. SINGLE / DUAL OPERATOR SELECTOR
SWITCH
- Parallel switch that allows the user to
choose between Single Operator and Dual Operator
weld modes. Single Operator mode is when the
switch is in the "Up" position. Dual Operator mode is
when the switch is in the "Down" position.
