TIG SOUND ac-dc 3340/T This is a new three-phase inverter power source for use in TIG and MMA-SMAW mode (except for cellulosic electrodes) designed for medium/large production rates. It is an innovative type of power source that allows you to operate in synergic mode; upon selecting the material to be welded, the corresponding thickness and the welding position, the power source sets and suggests the best welding condition. In addition, having in AC the option to choose among nine possible combinations of the three waveforms (square, delta, sine) allows the operator to customize both the penetration and cleanness of the welding bead. The machine also makes it possible to save up to nine welding programs. The machine may operate with pulsed arc, for intervention even on slim workpieces where transferred heat must be kept to a minimum.
