PRODUCT DESCRIPTION
The POWER MIG® 255XT is a complete semiautomatic
constant voltage DC arc welding machine built to meet
NEMA specifications. It combines a constant voltage power
source and a constant speed wire feeder with a
microcomputer-based controller to form a reliable high-
performance welding system. A simple control scheme,
consisting of continuous full range voltage and wire feed
speed controls, provides versatility with ease of use and
accuracy. The POWER MIG® 255XT is Spool Gun ready
and includes a second Gas Solenoid for Spool Gun use.
Refer to Accessories Section for Applicable Spool Guns.
Other features include a 2" (51 mm) O.D. wire reel spindle
with adjustable brake, an integral gas cylinder mounting
undercarriage, an adjustable CO

welding processes using 10 to 44 lb (4.5 to 20 kg) 2"(51 mm)
I.D. spools or Readi-Reel
®
coils (with optional adapter) of
.025" through .045" (0.6 – 1.2 mm) solid steel, .035" (0.9
mm) stainless, 3/64" (1.2 mm) aluminum and .045" (1.2 mm)
Outershield® and Ultracore® ; as well as .035" (0.9 mm) and
