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 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 .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, 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 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 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 accommo- date a significant drift in input power.

DESCRIPTION OF CONTROLS

Power ON/OFF Switch — Place the lever in the "ON" position to energize the POWER MIG 200.

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.

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.

WIRE DRIVE ROLL

The drive rolls installed with the POWER MIG each have two grooves, both for .030-.035" (0.8-0.9 mm) solid steel electrode. Drive roll size is indicated by the stenciling on the exposed side of the drive roll. If feed- ing problems occur, then the drive roll may be reversed or changed. See "Procedure for Changing Drive Roll" in this section.

WIRE SIZE CONVERSION PARTS

The POWER MIG 200 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.

IM693 specifications

Lincoln Electric IM693 is a cutting-edge multiprocess welding machine designed to cater to the needs of both industrial and commercial applications. Renowned for its versatility, this machine can perform MIG, TIG, and stick welding, making it an ideal choice for fabricators and manufacturers looking for a single solution for varied welding processes.

One of the standout features of the IM693 is its advanced inverter technology. This technology significantly enhances the efficiency of the welding process by reducing energy consumption while maximizing output. The inverter design allows for a more compact and lightweight unit compared to traditional transformers, making it easier to transport and maneuver in work environments.

The machine’s user-friendly interface is another compelling characteristic. It is equipped with a large, intuitive digital display that allows operators to quickly adjust settings for specific applications. The system is designed to provide real-time feedback on welding parameters, ensuring consistent and high-quality welds. This feature is particularly beneficial for both novice and experienced welders, facilitating a smoother workflow.

Additionally, Lincoln Electric IM693 incorporates advanced arc control technologies such as Soft Start and Auto Set features. Soft Start allows for a gradual ramp-up of the welding current, which minimizes spatter and leads to cleaner welds. The Auto Set feature intelligently adjusts the welder's settings based on the material type and thickness, taking the guesswork out of the welding process and improving overall efficiency.

The IM693 supports a wide range of input voltages, allowing for operation in various regions without the need for additional equipment. This flexibility makes it suitable for numerous applications, ranging from automotive repair to heavy machinery fabrication.

Safety is paramount in industrial settings, and the Lincoln Electric IM693 does not compromise on this front. It is equipped with several safety features such as thermal overload protection, which prevents machine damage from overheating, and a sturdy casing that protects vital components from dust and debris.

In summary, Lincoln Electric IM693 is a robust, versatile, and technologically advanced welding machine that meets the demands of modern welding applications. Its combination of inverter technology, user-friendly features, and safety measures makes it an excellent choice for professionals looking to achieve high-quality results with maximum efficiency.
