At Premier Welding we aim to offer amazing value for top quality products. The Kemppi Master T 245 AC/DC GM Water-Cooled is a professional AC/DC TIG and MMA welding system designed for welders who require maximum control, thermal stability, and productivity in demanding applications. Supporting single-phase 110V and 230V operation, as well as generator use, this advanced TIG welder delivers up to 240 amps, paired with a dedicated water-cooling unit for extended duty cycles and consistent torch performance.
The Master T range sets the benchmark for weld quality, usability, and energy efficiency in professional TIG welding. Smooth arc ignition, reduced noise levels in DC TIG welding, and excellent arc stability ensure consistent, high-quality results from start to finish. Weld Assist technology guides the welder to faster, more accurate setup, even at low current levels.
This water-cooled configuration is ideal for longer weld runs, higher current TIG work, and applications where heat management and operator comfort are critical. Designed and manufactured in Finland, the Master T system combines robust construction with advanced digital control for professional use in workshops or on site.
