A phenomenal welder. Arc time hours are shown in images, 66hrs. AC/DC 230 amp. AC frequency to 400hz, helps focus the arc when welding aluminium. DC pulse to 20,000Hz. Triangle wave, sine wave, square wave, soft square wave for AC welding. I love this welder but since closing the doors on my business i cant justify it sitting here when my other machine can do most of the work. It comes with a bluetooth foot pedal and 2 torches. 1 torch is the OEM supplied water cooled torch with hand trigger, the other is a CK 9 water cooled torch to be used with a foot pedal. It is a single phase power source with a water cooler running the fronius OEM coolant and i still have some spare. Paid 14k together with the ck torch and flex torch body for the OEM fronius torch when bought a couple of years ago. Price is negotiable, thanks
