OVERVIEW The MT200-AC/DC is a 220V/115V square wave AC/DC TIG inverter welder incorporating full TIG functionality including AC balance control, gas pre flow and post flow, variable pulse parameters, high frequency (HF) start, and remote current control. The HF start provides easy arc ignition leaving no tungsten inclusion and no contamination of the tungsten electrode. The pulse function with adjustable frequency and background current gives you the added capability to better control heat input into the work, control penetration and control distortion. The AC balance control lets you set the AC TIG arc for cleaning of the oxide layer on aluminum and adjust for a deeper penetrating weld. The foot control provides variable amperage adjustment during welding. Combining the functions of the MT200-AC/DC ensures comprehensive control of the welding parameters when welding both AC and DC, giving you the ability to produce professional TIG welds. The DC SMAW (stick) welding capability delivers a smooth and stable arc allowing easy welding with electrodes obtaining high quality welds with cast iron, stainless, and mild steels. The MT200-AC/DC has set the benchmark for 220V/115V single phase AC/DC welders and is ideal for multiple applications; aluminum and stainless steel fabrication, light industrial use, repair and maintenance. Robust and reliable, built to our specifications and manufactured in compliance to CAN/CSA E60974-1 & ANSI/IEC 60974-1.
