This brochure from Seal Group's Packing Division, Parker Hannifin (Hanover, NH) compares the basic capabilities of 10 plasma systems. Data includes cutting speeds, thickness capabilities, necessary gases, and more. The brochure also describes patented technologies "that differentiate the company's systems," it says. A table compares the company's plasma capabilities to those of laser and oxyfuel. A color graphic illustrates how different the company's systems perform on different metals at different thicknesses.
