WELDING CAPABILITY

The POWER MIG 215 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.

RECOMMENDED PROCESSES AND EQUIPMENT

The POWER MIG 215 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 steel, .035" (0.9 mm) stainless, 3/64" (1.2 mm) alu- minum and .035 (0.9 mm), .045" (1.2 mm) Outershield®; 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.

WIRE DRIVE ROLL

The drive rolls installed with the POWER MIG have two grooves one for .035(0.9mm) wire and the other for .045(1.2mm) wire. Drive roll size is indicated by the stenciling on the exposed side of the drive roll.

WIRE SIZE CONVERSION PARTS

The POWER MIG 215 is rated to feed .025 through

.045" (0.6-1.2 mm) solid or cored electrode sizes.

The drive roll kits and Magnum 250L gun and cable parts are available to feed different sizes and types of electrodes. See Accessories section.
