RANGER® 305D (AU)
B-7 OPERATION B-7
Ranger® 305D (AU) 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" contactor 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® 305D (AU) is used to set the maximum
range of the CURRENT CONTROL on the TIG Module
or an Amptrol if connected to the TIG Module.
WIRE WELDING-CV
Connect a wire feeder to the Ranger® 305D (AU)
according to the instructions in INSTALLATION
INSTRUCTIONS Section.
The Ranger® 305D (AU) in the CV-WIRE mode, per-
mits 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
preference. 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 applications with this machine.
ARC GOUGING
The Ranger® 305D (AU) can be used for limited arc
gouging. 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
positive)
1/8" 60-90 Amps
5/32" 90-150 Amps
3/16" 200-250 Amps
