The PROTIG 250 DC TRI is a 250 A three-phase TIG and MMA industrial power source with IP23 protection to withstand the harshest operating conditions. Ideal for welding on mild and stainless steels, it provides excellent starting quality and a very stable arc. Its power guarantees exceptional results even when joining materials of different thicknesses. Lightweight, compact and extremely robust, it's the ideal companion on the worksite.
DC Standard: smooth current welding on most ferrous materials.
DC Pulsed up to 900 Hz: controls the temperature of the molten pool, limits distortion and
allows the assembly of thin sheet metal from 0.3 mm.
Standard MMA: rutile and basic electrodes (up to Ø 4 mm).
MMA Pulsed up to 20 Hz: facilitates welding in a vertical upward position (pipes/
pipelines, etc.)
