Progys 300 Tri - Without Accessories
Heavy-Duty 300A Three-Phase MMA & TIG Lift Power Source
The PROGYS 300 TRI is a robust three-phase inverter welding power source designed for intensive industrial fabrication, maintenance, and site operations. Delivering a welding current range of 20–300A, it supports MMA (SMAW) and TIG Lift (GTAW) processes with exceptional arc stability and high productivity. Capable of welding rutile (6013), basic (7018), cellulosic (6010), and aluminium electrodes up to Ø6 mm, it also supports carbon arc gouging up to Ø5 mm. With a high duty cycle of 300A at 60% and a high no-load voltage of 83V, it ensures reliable ignition and strong arc dynamics, particularly for cellulosic applications. Built with reinforced structure, IP23 protection, optimised cooling, and optional VRD safety function, the PROGYS 300 TRI is engineered for harsh environments including shipyards, construction sites, and heavy industry.
