WORKHORSE : "A markedly useful or durable machine"...... Webster Dictionary
The Workhorse TIGweld 300ST is a very rugged capacitor discharge, auto start TIG/Stick welding machine, weighing approximately 90lbs/41Kgs, and designed specifically for demanding TIG welding where the tungsten (wolfram) electrode is not allowed to touch the base metal which could cause contamination of the weld. 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. This in combination with a capacitor discharge auto start makes the Workhorse TIGweld 300ST a remarkable TIG machine. The single pulse starting the arc does not produce radio noise, which can interfere with cell phones and other communication systems. For this reason, the capacitor discharge TIG welder is a better solution than high frequency (HF) systems, which do cause interference.
