Komatsu G9120 / G940 Fine Plasma Brochure - 2

SUPERIOR CUT QUALITY FROM GAUGE TO 1" THICK MATERIAL With Rasor™, smooth, square edges, minimal bevel angle, narrow kerf widths, and tight tolerances are simple and easy to achieve using our preprogrammed guidelines. INCREASED PRODUCTION RATES Komatsu’s patented fine plasma torch uses a magnetic field to constrict the plasma column.This combined with swirling assist gas technology provides superior cut quality and minimal bottom dross formation.This tightly focused plasma column creates a high energy density arc that enables Rasor™ Fine Plasma to provide much higher cutting speeds than...
