MMA welder / TIG / portable / three-phase

The PRESTO 300MV is an inverter technology power source for welding with coated electrodes (MMA) and TIG DC welding of carbon and stainless steels. It shows an important duty cycle (maximum 270 A) and thanks to the PFC (Power Factor Control) technology have a low primary consumption (16 A single-phase 220 V and 10 A at three phase 400 V).

The PRESTO 300MV is versatile and flexible. With single or three phase power supply, the power source can be connected to various electrical mains in the voltage range 180 V to 440 V (Autolink technology). In welding electrode coated it allows to use all types of electrodes (rutile, basic and cellulosic coating)

It has the Hot Start, Arc Force and integrated anti-stick functions for MMA welding and also the TIG Lift + function for the perfect control of striking and fainting phases in TIG welding.

Rugged, compact and light (22 kg) the PRESTO 300MV is the perfect companion for the most stringent on-site welding applications. It can be connected to a motor generator and with the VRD device (reduction of load voltage), it protects the welder during work in wet environments.
