PRODUCT DESCRIPTION
The POWER MIG™ 200 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.
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 12 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 Spool Gun and Adapter kit, Dual Cylinder Mounting kit and Aluminum Feeding Kit for push feed- ing with standard built in feeder are also available.
RECOMMENDED PROCESSES AND EQUIPMENT
The POWER MIG 200 is recommended for GMA weld- ing processes using 10 to 44 lb (4.5 to 20 kg) 2" (51
mm)I.D. spools or
steel, .035" (0.9 mm) stainless, 3/64" (1.2 mm) alu- minum and .045" (1.2 mm) Outershield® ; as well as
.035" (0.9 mm) and .045" (1.2 mm) Innershield® self- shielding electrodes.
LIMITATIONS
The output voltage/current of the POWER MIG 200 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 accommodate a signifi- cant drift in input power.
DESCRIPTION OF CONTROLS
Power ON/OFF Switch — Place the lever in the "ON" position to energize the POWER MIG 200. See Figure B.1.
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 compartment door. See Figure B.?.
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. See Figure B.1.

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, 12 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 200 is rated at 200 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 cur- rents. The tapped transformer design makes it well suited for use with most portable or
