Powermax125 plasma system Hypertherm

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.


Maximum productivity
  • Finish jobs faster with cut speeds five times greater than oxyfuel on 12 mm (1/2”) mild steel
  • Superior cut and gouge quality let you spend less time on grinding and edge preparation
  • 100% duty cycle maximizes your cutting time
  • Multiple, easy-to-use torch styles let you tackle a wide variety of jobs using the same system

Easy-to-use for cutting and gouging

  • No need to change the air pressure – Smart Sense™ technology ensures that it is always correctly set
  • SpringStart™ technology ensures consistent starting and a more reliable torch
  • Drag cut at full output with a patented shield that reduces dross buildup for smoother cutting

Lower operating costs

  • Consumable life up to four times longer than other systems in this amperage range
  • Electrode end-of-life detection protects the torch and workpiece from damage by automatically stopping power when the electrode is overused

Built to handle tough jobs

  • Hypertherm Certified™ reliability ensures peak performance even in the harshest environments
  • Duramax Hyamp torches are designed for high-impact and heat resistance
