Laser cutting, waterjet and plasma cutting machines are what Hypertherm is all about. This unique focus on high-quality plasma cutters has positioned Hypertherm as an industry leader.
Our top pick, the Hypertherm Powermax 45, produces 10 to 45 amps, enough cutting power to accurately cut through ⅝-inch-thick steel. It is designed for industrial use to cut metal in a factory environment. This unit has dual 240/480 volt power inputs. Smart Sensor is Hypertherm’s compressed air automatic setting system.
It has a torch disable switch for changing the torch assembly. Quick-change technology quickly reconfigures torch style and tip size for clean cuts. Owners raved about the high-quality work done by the Hypertherm Powermax 45, praising its precise cuts, high inches per minute rating, and smooth edges. That has a lot to do with why we chose it as the best plasma cutter.
The only downside to this model is the lack of a CPC port, making it impossible to control it from a computer. Fortunately, the ports can be retrofitted with Hypertherm’s kit. The Powermax 45 comes with a 3-year warranty on the power system and a 1-year warranty on the flashlight.
