RANGER 305D
B-6
OPERATION
B-6
RANGER 305 D settings when using the K930-2 TIG Module with
an Amptrol or Arc Start Switch:
• Set the MODE Switch to the TOUCH START TIG setting.
• Set the "IDLER" Switch to the "AUTO" position.
• Set the "WELDING TERMINALS" switch to the "REMOTELY
CONTROLLED" position. This will keep the "Solid State" con-
tactor open and provide a "cold" electrode until the Amptrol or
Arc Start Switch is pressed.
When using the TIG Module, the OUTPUT control on the
RANGER 305 D is used to set the maximum range of the CUR-
RENT CONTROL on the TIG Module or an Amptrol if connected
to the TIG Module.
WIRE WELDING-CV
Connect a wire feeder to the RANGER 305 D according to the
instructions in INSTALLATION INSTRUCTIONS Section.
The RANGER 305 D in the CV-WIRE mode, permits it to be used
with a broad range of flux cored wire (Innershield and
Outershield) electrodes and solid wires for MIG welding (gas
metal arc welding). Welding can be finely tuned using the ARC
CONTROL. 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/pinch control. The
proper setting depends on the procedure and operator prefer-
ence. Start with the dial set at 0.
Listed below are some wires suitable for use on this machine:
• Innershield - NR-311, NS-3M, NR-207, NR-203 Ni 1%,
NR-212.
• Outershield - 0S-70, 0S-71M, 0S-71 ELITE.
• Solid wires for MIG welding - .035 (0.9 mm), and
.045 (1.1 mm), Super Arc L-50 and L-56, .035 (0.9 mm) and
.045 (1.1 mm) Blue Max MIG 308 LS.
Contact your local authorized Lincoln Electric Distributor or the
Lincoln Electric Company for specific wires used on certain appli-
cations with this machine.
ARC GOUGING
The RANGER 305D can be used for limited arc goug-
ing. For optimal performance, set the MODE switch to
CC-STICK and the ARC CONTROL to +10.
Set the OUTPUT CONTROL knob to adjust output
current to the desired level for the gouging electrode
being used according to the ratings in the following
Table.
Carbon Diameter
Current Range (DC, electrode

1/8" 60-90 Amps
5/32" 90-150 Amps
3/16" 200-250 Amps
