The EDGE3S has all the features of the EDGE3, plus the Makino EDGE3 S-series is HQSF™ (High-Quality Surface Finish) capable, with a standard 60 amp power supply and a sludge separator required. HQSF™ uses a powder additive that is mixed with the dielectric fluid to improve electrical conductivity for more consistent discharging and spark diffusion. This diffusion provides a smaller crater for a superior finish without a loss in metal removal rates.
