RANGER® 225
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”.
