Powermax125 plasma cutter

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.

System information


Drag cutting

For dragging the torch directly across the work piece

Fine feature cutting

For narrow kerf width with minimal dross and heat affected zone

Flush cutting

For cutting closer to base materials using a 45 degree

Max control gouging

For precise metal removal, shallower gouge profiles and light metal washing

Max removal gouging

For aggressive metal removal, deep gouge profiles, and extreme metal washing

Mechanized cutting

For portable automation and table cutting

Unsupported Applications

Extended reach cutting

For improved visibility and accessibility when cutting in confined spaces

Extended reach gouging

For improved visibility and accessibility when gouging in confined spaces


For scoring, indicating part identification, hole or weld locations

Precision gouging

For spot and tack weld removal at very low output current (<25 A)


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
