In the CV-WIRE mode, if the wire feeder has
voltage control capability, when the 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 TOUCH START TIG mode and when a
Amptrol is connected to the 6-Pin Connector, the
OUTPUT control is used to set the maximum
current range of the CURRENT CONTROL of the
Amptrol.
2. Digital Output Meters: The digital meters allow the
output voltage (CVWIRE mode) or current (CC-
STICK, PIPE and TIG modes) to be set prior to
welding using the OUTPUT control dial. During
welding, the meter display the actual output voltage
(V) and current (A). A memory feature holds the
display of both meters on for seven seconds after
welding is stopped. This allows the operator to read
the actual current and voltage just prior to when
welding was ceased.
While the display is being held the left-most decimal
point in each display will be flashing. The accuracy
of the meters is +/- 3%.
3. Weld Mode Selector Switch: (Provides four
selectable welding modes)
CV-WIRE
DOWNHILL
PIPE
CC-STICK
TOUCH
START
TIG
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 preferred 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 recommended 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.
6. Ground
Stud
: Provides a connection point for
connecting the machine case to earth ground.
7. 14-pin Connector: For attaching wire feeder control
cables to the RANGER® 305D (CE). Includes
contactor closure circuit, auto-sensing remote
control circuit, and 42V power. The remote control
circuit operates the same as the 6 Pin connector.
Note: The 14-pin connector does not include 120V.
8. 6-pin Connector: For attaching optional remote
control equipment. Includes auto-sensing remote
control circuit.
9. Weld Terminals Switch: In the WELD TERMINALS
ON position, the output is electrically hot all the
time. In the REMOTELY CONTROLLED position,
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.

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. Glow plug
should not be activated for more than 20 seconds
continuously.
13. Start Push Button:
Energizes the starter motor to crank engine.
