“Delivering maximum power and performance for air plasma, the Powermax125® plasma system cuts thick metals fast. Able to make short work of the toughest cutting and gouging jobs, the system offers a 100% duty cycle, a 25 mm (1″”) mechanized pierce capability, and fast gouging metal removal. It also gives you the latest technological innovations, such as Smart Sense™ technology to automatically adjust the gas pressure. Eleven Duramax™ Hyamp torch styles provide versatility for hand cutting, portable automation, X-Y table cutting, extended reach cutting, and robotic cutting and gouging.
This model includes the Powermax125® Power Supply (480V) with CPC port and voltage divider, the Duramax 25ft hand held torch with 85 degree head and a standard work lead. The CPC port and voltage divider are used to connect CNC controllers (Computer aided cutting machines) to the Powermax line of machines. Hypertherm’s “CSA” models are for use in the Americas and Asia, except China.
