7 Functions in 1 Machine: The TL-220TP PRO is a 220A 7-in-1 welder that supports high-frequency TIG welding, lift TIG welding, pulse high-frequency TIG welding, pulse lift TIG welding, cold spot TIG welding, cold spot lift TIG welding, and arc welding. Cold spot TIG: The cold spot welding function is suitable for precision parts, heat-sensitive materials, and products with high appearance requirements, minimizing the risk of deformation and discoloration. Convenient Control: This welder is compatible with the TOOLIOM 5-pin foot switch, enabling remote control of the entire TIG welding process without needing to manually adjust the current switch. This saves time, enhances efficiency, and boosts productivity. (Note: The foot switch is not included.) Powerful Stick Welding: Delivers up to 220A with integrated Hot Start and Arc Force for superior Stick welding performance. Large-sized LED display screen: The intelligent LED screen displays welding functions and processes, accurately showing welding data. The panel knobs can adjust welding parameters, while the buttons can select 2T/4T/4T PRT modes, control welding modes, and corresponding parameters.
