Applications

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

Benefits

Benefits

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
Powermax125 cut performance chart

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
