We present you a premium TIG welding solutions that eliminates troublesome control and mains power cables, also removing related health and site safety risks, cable management and site maintenance issues. The air cooled electronic power source is ideal for challenging environments, including high ambient temperatures, humidity and subzero work site conditions. Powered from any DC welding power source that provides a minimum of 40 V pole voltage, including welding generators, Stick (MMA) and MIG/ MAG sources, MasterTig LT 250 provides a most versatile DC TIG solution. Kemppi's KempGouge is an ideal parent power source solution providing enough power to run up to 4  LT 250 units at full power simultaneously.

Precise ignition in both DC TIG and Stick (MMA) process makes welding easy, reliably serving applications using extended torch lengths. The digital display provides clear reference for pre-set welding values and parameter setting is logical, easy and accurate. The rear panel mounted gas control meter allows localized shielding gas flow control and weighing only 12.6 kg, MasterTig LT 250 is easy to carry to site using the standard fabric shoulder strap.
