Single knob voltage controlwire feed. Class FH insulation Spot welding Timer Facility Light weight feeder with quick change over mechanism We offer 3 in 1 facility i.e. MMA TIG MIG in single power source.

Consist of Power source with controls, Water re circulating system if required and a well designed Torch. The basic principle is that the arc formed between the electrode and the work piece is constricted by a fine bore, copper nozzle. This increases the temperature and velocity of the plasma emanating from the nozzle. The temperature of the plasma is in excess of 20 000°C and the velocity can approach the speed of sound. When used for cutting, the plasma gas flow is increased so that the deeply penetrating plasma jet cuts through the material and molten material is removed in the efflux plasma.
