Air Vent Inc IM10065 OIL Pressure Gauge, Engine Protection, BATTERY Charging Light, Idler Switch

b-3 OPERATION b-3

6. OIL PRESSURE GAUGE

The gauge displays the engine oil pressure when the engine is running.

7. ENGINE PROTECTION

The yellow engine protection light remains off with proper oil pressure and under normal oper- ating temperatures. If the light turns on, the engine protection system will stop the engine. Check for proper oil level and add oil if neces- sary. Check for loose or disconnected leads at the oil pressure sender located on the engine. The light will remain on when the engine has been shut down due to low oil pressure or over- temperature condition.

8. bATTERY CHARGING LIGHT

The yellow engine alternator light is off when bat- tery charging system is functioning normally. If light turns on the alternator or the voltage regula- tor may not be operating correctly. The light will remain on when the engine is stopped and the run/stop switch is in the run position.

9. IDLER SWITCH

Has two positions as follows:

A)In the “High” position , the engine runs at the high idle speed controlled by the governor.

B) In the “Auto”	/	position, the
idler operates as follows:

a. 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.

b. 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.

c. When welding ceases and the AC power load is turned off, a fixed time delay of approximate- ly 12 seconds starts.

d. If the welding or AC power load is not restart- ed before the end of the time delay, the idler reduces the engine speed to low idle speed.

e. The engine will automatically return to high idle speed when the welding load or AC power load is reapplied.

Idler Operational exceptions

When the WELDING TERMINALS switch is in the “Remotely Controlled” position the idler will operate as follows:

a. When the triggering device (Amptrol, Arc Start Switch, etc.) is pressed the engine will acceler- ate and operate at full speed provided a weld- ing load is applied within approximately 12 seconds.

•If the triggering device remains pressed but no welding load is applied within approximately 12 seconds the engine may return to low idle speed.

•If the triggering device is released or welding ceases the engine will return to low idle speed after approximately 12 seconds.

WELDING CONTROLS (Items 10 through 19)

10. OUTPUT CONTROL:

The OUTPUT dial is used to preset the output voltage or current as displayed on the digital meters for the four welding modes. When in the

CC-STICK, DOWNHILL PIPE or CV-WIRE modes and when a remote control is connected to the 6-Pin or 14-Pin Connector, the auto-sens- ing circuit automatically switches the OUTPUT CONTROL from control at the welder to the remote control.

In the CV-WIRE mode, when the wire feeder control cable is connected to the 14-Pin Connector, the auto-sensing circuit automatically makes OUTPUT CONTROL inactive and the wire feeder voltage control active.

When in the DOWNHILL PIPE mode and when a remote control is connected to the 6-Pin or 14- Pin connector, the output control is used to set the maximum current range of the remote.

EXAMPLE: When the OUTPUT CONTROL on the welder is set to 200 amps the current range on the remote control will be 40-200 amps, rather than the full 40-300 amps. Any current range that is less than the full range provides finer current resolution for more fine tuning of the output.

When in the TOUCH START TIG mode and when a Amptrol is connected to the 6-Pin Connector, the OUTPUT dial is used to set the maximum current range of the CURRENT CON- TROL of the Amptrol.
