WIRE FEED WELDING PROCESSES
(CONSTANT VOLTAGE)
The Innershield ® electrode recommended for use with
the RANGER® 225 is NR ® -211-MP. The electrode
sizes and welding ranges that can be used with the
RANGER® 225 are shown in the following table:
The RANGER® 225 is recommended for limited “MIG”
welding (GMAW - gas metal arc welding). The recom-
mended electrodes are .030” and .035” L-50 and L-56.
They must be used with a blended shielding gas such
as C25 (75% Argon - 25% CO
2
). The welding ranges
that can be used with the RANGER® 225 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
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® 225 can be used for limited arc goug-
ing.
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:
* When welding with MIG wire instead of self-shielded core wire, weld starts can be improved by setting the idle
mode to “HIGH”.
STICK No AUTO Hot Touch electrode to work.
Welding starts immediately
and engine goes to high
idle.
WIRE FEED, LN-25 WITH No AUTO Cold Press gun trigger, LN-25
INTERNAL CONTACTOR contactor closes. Welding
starts immediately and
engine goes to high idle.
Note: Output Control
must be set above “3”.
*
TIG, TIG MODULE WITH Yes HIGH Cold Press Amptrol,
WITH CONTACTOR KIT contactor closes,
CONTROL CABLE, & welding starts immediately.
AMPTROL
WIRE FEED, LN-15 No AUTO Cold Press gun trigger.
ACROSS the ARC LN-15 contactor closes,
(has internal contactor) Welding starts immediately
and engine goes to “HIGH”
Idle.
Note: Output Control must
be set above “3”.
