True to its name, the portable Workhorse MIGweld 300MS is a very rugged multi-process MIG/Stick welding machine, weighing approximately 80 lbs/36.3 Kgs, and designed specifically for the industrial market. The underlying design concept was to employ proven electrical and mechanical technologies and build a “no-nonsense”, cost-effective machine where usability, reliability and ruggedness are the most important design parameters. The electric circuitry is based on principles that over the years have proven their functionality and reliability in the over 100,000 welding machines sold and used around the world. The fiberglass reinforced plastic case also provides unique benefits over the sheet metal and thermoplastic cases used in most competing products.
