Flame cutting (oxy-fuel) slices carbon-steel plate up to 8″ thick with a focused jet of oxygen that literally burns the metal away, delivering square edges at production speed and low cost. Hi-definition plasma, meanwhile, blasts ionized gas through a tiny nozzle to melt and blow out material, giving laser-like precision on stainless, aluminum, or mild steel up to 1½″—all while handling complex contours in a single pass.
