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 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.
