The Mitsubishi EA12ST Advance Sinker EDM has all the same great features as the EA12S Advance, but offers a larger fixed worktank to better accommodate a rotary table or larger workpiece. It features the new MITSUBISHI M700 series control with 15” touch screen and FP80S energy saving power supply, reducing electrical consumption by 20% (as compared to the previous FP model). The all new IDPM “Intelligent Digital Power Master” Adaptive Control reduces graphite electrode wear by as much as 40%. The addition of the new SS Jump 5 system optimizes jump up acceleration control to stabilize high speed No-Flush burning
