CV-WIRE mode: In this mode, turning the ARC CONTROL
clockwise from –10 (soft) to +10 (crisp) changes the arc
from soft and washed-in to crisp and narrow. It acts as an
inductance control. The proper setting depends on the pro-
cedure and operator preference. Start with a setting at 0.
5. WELD OUTPUT TERMINALS WITH FLANGE
NUT:
Provides a connection point for the electrode and work
cables.
6. GROUND STUD:
Provides a connection point for connecting the machine
case to earth ground for the safest grounding procedure.
7. 14 PIN CONNECTOR:
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 CONNECTOR:
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 OUTPUT
control on the front of the RANGER® 305G is used to set
the maximum current range of the CURRENT CONTROL
on the TIG Module.
9. WELD TERMINALS CONTROL SWITCH:
In the WELD TERMINALS ON position, the output is elec-
trically hot all the time. In the REMOTELY CONTROLLED
position, the output is controlled by a wire feeder or amp-
trol 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:

11. RUN/STOP SWITCH
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.
OPERATION
- RUN position energizes the
RANGER® 305LPG
12. CHOKE
- When pulled out, it closes the choke valve
on the engine carburetor for quick starting.
13. START PUSH bUTTON
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 fol-
lows:
• 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 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.
15. HOUR METER
The hour meter displays the total time that the
engine has been running. This meter is useful for
scheduling prescribed maintenance.

STARTING AND STOPPING THE ENGINE

• Remove all plugs connected to the AC power recep-
tacles.
• 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.
• The engine will run at high idle speed for approxi-
mately 12 seconds and then go to low idle speed.
Allow the engine to warm up at low idle for several
minutes before applying a load and/or switching to
high idle. Allow a longer warm up time in cold
weather.
