Description
Maximum Power and Durability for Extreme Plasma Cutting Demands
The Powermax125® is Hypertherm’s most powerful air plasma system, engineered for high-demand cutting and gouging in industrial settings. Capable of piercing up to 25 mm (1″) and cleanly severing thicker metals, it delivers consistent, fast results with a 100% duty cycle at full output. Advanced features like Smart Sense™ technology automatically optimize gas pressure, while a wide range of 11 Duramax™ Hyamp torch styles ensures precision across manual, mechanized, and robotic applications.
6 Year Powermax power supply warranty
Enjoy Hypertherm’s extended Powermax 6‑year warranty on the power supply (600,000 starts), plus 12 month coverage on torches and leads—no extra registration required. Learn more about the Hypertherm 6 year power supply warranty here.
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
