PROTIG 250 DC TRI is a 250 A three-phase TIG and MMA industrial power source with IP23 protection for use in the most difficult conditions. Ideal for welding on mild and stainless steels, it ensures excellent ignition quality and a very stable arc. Its high output ensures exceptional results, even when joining materials of different thicknesses. Lightweight, compact and extremely robust, it is the ideal tool for use on site.

WELDING PROCESSES

• TIG DC DC Standard: smooth current welding on most ferrous materials.
• DC Pulse up to 900 Hz: controls the temperature of the weld pool, limits workpiece
  deformation and allows assembly of thin sheets, as fine as 0.3 mm.
• MMA Standard: rutile and basic electrodes (up to Ø 4 mm).
• MMA Pulse up to 20 Hz: facilitates welding in a rising vertical orientation (pipes/pipelines, etc.).
