Lincoln Electric IM978 POWER MIG 215XT - Manual (Page 14)

B-2 B-2 OPERATION
PRODUCT DESCRIPTION
The POWER MIG™ 215XT is a complete semiauto-
matic DC voltage arc welding machine built to meet
NEMA specifications. It combines a tapped trans-
former voltage power source with a constant speed
wire feeder to form a reliable robust performance
welding system. A simple control scheme, consisting
of continuous full range wire feed speed control, and 7
output voltage tap selections provides versatility with
ease of use and accuracy. An enhanced feature to the
POWER MIG™ 215XT, is that it is Magnum 100SG
Spool Gun ready.
Other features include a 2" (51 mm) O.D. wire reel
spindle with adjustable brake, an integral gas cylinder
mounting undercarriage, an adjustable Argon blend
flow regulator with cylinder pressure gauge and inlet
hose, a 15 ft. (3.6 m) Magnum 250L GMAW gun and
cable with fixed (flush) nozzle, a 7 ft. (2.1 m) power
cable with plug, and a 10 ft. (3.0 m) work cable with
clamp.
Optional Magnum Spool Gun, Push-Pull Guns and
Adapter kits, Dual Cylinder Mounting kit and
Aluminum Feeding Kit for push feeding with standard
built in feeder are also available.
RECOMMENDED PROCESSES AND
EQUIPMENT
The POWER MIG® 215XT is recommended for GMA
welding processes using 10 to 44 lb (4.5 to 20 kg) 2"
(51 mm) I.D. spools or Readi-Reel
® coils (with option-
al adapter) of .025" through .045" (0.6 – 1.2 mm) solid
wire, .035" (0.9 mm) stainless, 3/64" (1.2 mm) alu-
minum, .035 (0.9 mm), .045" (1.2 mm) Outershield
®
and .045”(1.2mm) Ultracore ® as well as .035" (0.9
mm) and .045" (1.2 mm) Innershield ® self-shielding
electrodes.
The POWER MIG is factory equipped to feed .035"
(0.9 mm) electrodes. It also includes a 200A, 60%
duty cycle (or 250A, 40% duty cycle) rated, 15 ft. (3.6
m) GMAW gun and cable assembly equipped for
these wire sizes. Use of GMAW processes requires a
supply of shielding gas.
WELDING CAPABILITY
The POWER MIG® 215XT is rated at 215 amps @ 22
volts, at a 30% duty cycle based on a ten minute cycle
time. It is capable of higher duty cycles at lower output
currents. The tapped transformer design makes it
well suited for use with most portable or in-plant gen-
erating systems.
LIMITATIONS
The output voltage/current of the POWER MIG®
215XT is subject to vary if the input power to the
machine varies, due to its tapped transformer power
topology. In some cases an adjustment of WFS pre-
set and/or voltage tap selection may be required to
accommodate a significant drift in input power.
DESCRIPTION OF CONTROLS
See Figure B.1
1. Power ON/OFF Switch — Place the lever in the
"ON" position to energize the POWER MIG®
215XT.
2. Voltage Control — Seven voltage tap selections
are provided Labeled "A" (minimum voltage)
through "G" (maximum voltage). It should only be
adjusted when not welding. The control selection
can be preset to the setting specified on the
Procedure Decal on the inside of the wire compart-
ment door.
3. Wire Speed Control — This controls the wire feed
speed from 50 – 700 inches per minute (1.2 – 17.8
m/min). Wire speed is not affected when changes
are made in the voltage control.
