Three-phase inverter TIG welder
200 - 500 A | PI Migatronic

Pi 200 and Pi 250 are for quality welding operations in TIG AC/DC and MMA. You have never seen such a variety of readily accessible facilities for TIG weld-ing: increased programming, simple operation and user-friendly design, as well as inverter technology combined with innovative operation and communi-cation possibilities.

Mono-phase and three-phase
A high-performance mono-phase or three-phase Pi machine is always available and perfect for a wide range of TIG and MMA welding operations. Both the Pi 200 and the Pi 250 are available in three ersions, all of which have easy-to-use control panels:

Pi DC for MMA welding with simple TIG LIFTIG®.
Pi DC HP - TIG with pulse and Synergy Plus™ as standard features.

Three optional pulses:
Pi offers three optional pulse versions: traditional manual pulse, quick pulse, and Synergy Plus™ for DC welding which automatically adjusts all overarching pulse para-meters. Another advantage of Synergy Plus™ is that the traditional sound in pulse welding has been replac-ed by a sound that does not cause stress. Pi 200 HP and Pi 200 AC/DC, the two mono-phase machines, feature PFC (Power Factor Correction), a function that makes it possible to weld with up to 200 A if only 16 A mains fuses are available.
Controlled cleaning zone:
All Pi AC/DC machines - including the mono-phase version - are fitted with the D.O.C.® system,Miga-tronic's revolutionary dynamic oxide control. In
welding aluminium, D.O.C.® ensures a controlled cleaning zone along the weld, increases the welding speed by up to 30% and reduces the consumption of energy and tungsten electrodes correspondingly.
