WIRE FEED WELDING PROCESSES (CONSTANT VOLTAGE)

The Innershield® electrode recommended for use with the RANGER® 3 PHASE is NR®-211-MP. The elec- trode sizes and welding ranges that can be used with the RANGER® 3 PHASE are shown in the following table:

Diameter	Wire Speed		Approximate
(in.)	Range In./Min.		Current Range
.035	80	- 110	75A to 120A
.045	70	- 130	120A to 170A
.068	40	- 90	125A to 225A

The RANGER® 3 PHASE is recommended for limited “MIG” welding (GMAW - gas metal arc welding). The recommended electrodes are .030” and .035” L-50 and L-56. They must be used with a blended shield- ing gas such as C25 (75% Argon - 25% CO2). The welding ranges that can be used with the RANGER®

3 PHASE are shown in the following table:

Diameter	Wire Speed		Approximate
(in.)	Range In./Min.		Current Range
.030	75	- 300	50A to 130A
.035	100	- 250	90A to 175A

ARC GOUGING

The RANGER® 3 PHASE can be used for limited arc gouging.

Set the Range switch to adjust output current to the desired level for the gouging electrode being used according to the ratings in the following table:

ELECTRODE	CURRENT RANGE
SETTING	(DC, electrode positive)
1/8	30	-	60 Amps
5/32	90	-	150 Amps
3/16	150 - 250 Amps

*When welding with MIG wire instead of self-shielded core wire, weld starts can be improved by setting the idle mode to “HIGH”.
