PRODUCT DESCRIPTION

The Power MIG® 215XT is a complete semiautomatic DC voltage arc welding machine built to meet NEMA specifications. It combines a tapped transformer volt- age 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 feed- er 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 generating 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 preset and/or voltage tap selection may be required to accom- modate 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.
