The paper presents several original GMAW torches destined for special/universal welding processes. The first category is destined for underwater welding with local drying. The technical designing variants are original, but the fundamental is already known: an air or water curtain is providing a protected area, not permitting the access of the water (compensating the exterior hyperbaric pressure with the dynamic pressure of the curtain). The protecting gas is classically introduced in the welding arc aria. The second category of torches presented is used in heavy-duty GMAW welding processes, any welding position (antigravity welding). One or two cooling parts are included, in order to permit high values for the welding current intensity. Special materials and technical designing variants were used. These torches were developed i
