5.WELD OUTPUT TERMINALS WITH FLANGE NUT:

Provides a connection point for the electrode and work cables.

6. GROUND STUD: (graphic)

Provides a connection point for connecting the machine case to earth ground for the safest grounding procedure.

7. 14 PIN AMPHENOL:

For attaching wire feeder control cables to the RANGER 305G. Includes contactor closure circuit , auto-sensing remote control circuit, and 120V and 42V power. The remote control circuit operates the same as the 6 Pin Amphenol.

8. 6 PIN AMPHENOL:

For attaching optional remote control equipment. When in the CC-STICK, PIPE, and CV-WIRE modes and when a remote control is connected to the Amphenol, the auto-sensing circuit in the RANGER 305G automatically switches the OUTPUT control from control at the welder to remote control .

When using the TOUCH START TIG mode with a TIG Module connected to the RANGER 305G, the OUT- PUT control on the front of the RANGER 305G is used to set the maximum current range of the CUR- RENT CONTROL on the TIG Module.

9. WELD TERMINALS CONTROL SWITCH:

In the WELD TERMINALS ON position, the output is electrically hot all the time. In the REMOTELY CON- TROLLED position, the output is controlled by a wire feeder or amptrol device, and is electrically off until a remote switch is depressed.

14.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 follows:

When switched from HIGH to AUTO or after start- ing 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 l o a d 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.

15.ENGINE ALTERNATOR TROUBLE LIGHT-The engine alternator light is off when battery

charging system is functioning normally. If light turns on, the alternator or the voltage regulator may not be operating correctly. The light may also come on due to the battery not holding a charge. It is normal for the light to come on during shutdown of the engine. The light will remain lit with the meters for a short period of time after the engine has shut down.

16.ENGINE HOUR METER – Displays the total time that the engine has been running. This meter is useful for scheduling prescribed maintenance.

10. WIRE FEEDER VOLTMETER SWITCH:

Matches the polarity of the wire feeder voltmeter to the polarity of the electrode.

ENGINE CONTROLS:

11.RUN/STOP SWITCH - RUN position ener- gizes the engine prior to starting. STOP position stops the engine. The oil pressure interlock switch prevents battery drain if the switch is left in the RUN position and the engine is not operating.

12.CHOKE - When pulled out, it closes the choke valve on the engine carburetor for quick starting.

13.START PUSH BUTTON - Energizes the starter motor to crank the engine.

STARTING AND STOPPING

THE ENGINE

Remove all plugs connected to the AC power receptacles.

Set IDLER switch to AUTO.

Set the RUN/STOP switch to RUN.

Pull the choke to the full out position.

Press and hold the engine START button until the engine starts.

Release the engine START button when the engine starts.

Push the choke back in.
