4.ARC CONTROL- The ARC CONTROL dial is active in the CV-WIRE, CC-STICK and DOWNHILL PIPE modes, and has different functions in these modes. This control is not active in the TIG mode.

CC-STICK mode: In this mode, the ARC CONTROL dial sets the short circuit current (arc-force) during stick welding to adjust for a soft or crisp arc. Increasing the dial from –10 (soft) to +10 (crisp) increases the short circuit current and prevents sticking of the electrode to the plate while welding. This can also increase spatter. It is recommended that the ARC CONTROL be set to the minimum number without electrode sticking. Start with a setting at 0.

DOWNHILL PIPE mode: In this mode, the ARC CONTROL dial sets the short circuit current (arc-force) during stick welding to adjust for a soft or a more forceful digging arc (crisp). Increasing the number from –10 (soft) to +10 (crisp) increases the short circuit current which results in a more forceful digging arc. Typically a forceful digging arc is pre- ferred for root and hot passes. A softer arc is preferred for fill and cap passes where weld puddle control and deposition ("stacking" of iron) are key to fast travel speeds. It is recom- mended that the ARC CONTROL be set initially at 0.

CV-WIRE mode: In this mode, turning the ARC CONTROL clock wise from –10 (soft) to +10 (crisp) changes the arc from soft and washed-in to crisp and narrow. It acts as an inductance/pinch control. The proper setting depends on the procedure and operator preference. Start with a setting of 0.

5. WELD OUTPUT TERMINALS WITH FLANGE NUT- Provides a connection point for the electrode and work cables. Output stud covers provided on code 11275 and above.

6.GROUND STUD- Provides a connection point for connecting the machine case to earth ground.

7.14-PIN CONNECTOR- For attaching wire feeder con- trol cables to the RANGER 305D. Includes contactor clo- sure 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 CONNECTOR- For attaching optional remote control equipment. Includes auto-sensing remote control circuit.

9.WELD TERMINALS CONTROL SWITCH- In the WELD TERMINALS ON position, the output is electrically hot all the time. In the REMOTELY CONTROLLED posi- tion, the output is controlled by a wire feeder or amptrol device, and is electrically off until a remote switch is depressed.

10. WIRE FEEDER VOLTMETER SWITCH:

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

ENGINE CONTROLS: (Figure B.2)

11.RUN/STOP SWITCH - RUN position energizes 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. GLOW PLUG PUSH BUTTON -

When pushed activates the glow plugs as well as the electric fuel pump for quick starting. Glow plug should not be activated for more than 20 seconds continuously.(For Code 11121)

AUTO BLEED FUNCTION – Air will automatically bleed from the fuel system by simply pushing the GLOW PLUG BUTTON. It is generally not required to crack open fittings in the fuel system to bleed air from the fuel system.(For Code 11121)

When pushed activates the glow plugs. Glow plug should not be activated for more than 20 seconds continuously.(For Code 11188, 11275)

13.START PUSH BUTTON -

Energizes the starter motor to crank the engine.

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 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.
