Master- and Mastertig-power sources are MMA and TIG power sources designed for
demanding professional use.
Master- and Mastertig-power sources are IGBT-inverters, controlled by PWM-principle.
Operation frequency is approx. 18 kHz.
5 power source sizes are available; 1~ 140 A, 1~ 150 A, 3~ 220 A, 3~ 280 A and 3~ 350 A
