PowerMaster 256
Three-phase multi-process: 250 A AC/DC TIG and 60 A plasma.
The PowerMaster 256 is the heaviest Granhult multi-process machine. 400 V input delivers 250 A for TIG and 60 A for plasma while drawing just 11 A. It ships with a water-cooling-ready TIG torch, a plasma torch and a water separator.
The plasma severs up to 25 mm and cuts cleanly to about 16 mm. Both TIG and plasma use HF start, and the torches swap over on quick connectors.
TIG controls match the EX series: pulse 0.5–250 Hz, pulse width and background current, AC frequency 20–250 Hz, slopes, pre-flow and post-flow.
Optional: ICE water cooling unit, cart and foot pedal.
