Thermal Dynamics CUT40 TD Cutmaster 40 Plasma Cutter with SL60 1Torch

Thermal Dynamics CUTMASTER 40 Plasma Cutter with SL60 1Torch

The Thermal Dynamics Cutmaster® 40 is a compact yet incredibly powerful plasma cutter designed for professionals who need portability without compromising performance. At just 22 lbs (10 kg), it delivers the highest power-to-weight ratio in its class, making it the ultimate balance of mobility, durability, and cutting precision. Whether you’re working in a shop, on a jobsite, or tackling mobile repairs, this machine offers exceptional flexibility with automatic voltage input detection from 110V to 240V. It automatically adjusts the output to 27 amps at 110V or 40 amps at 200–240V, ensuring you always get maximum performance regardless of the power source.

Engineered with end-user insight and industrial-grade durability, the Cutmaster 40 is built for real-world conditions. Its multi-handle housing design makes carrying and setup easy, while the rugged IP23-rated case ensures it can withstand tough environments, indoors or outdoors. Thermal Dynamics also equips this machine with its legendary SL60 1Torch® featuring ATC® (Advanced Torch Connector), giving operators the ability to quickly disconnect and replace torch leads without tools—an essential feature for reducing downtime. The Cutmaster Black Series electrode extends consumable life up to 60% longer than standard electrodes, cutting consumable costs while keeping productivity high.

Despite its lightweight frame, the Cutmaster 40 is a serious workhorse. With a recommended cut and pierce capacity of ½ inch (12 mm) and a severance capacity of up to 1 inch (25 mm), it delivers precise, clean cuts on mild steel, stainless steel, and aluminum. The arc length is best-in-class, which means superior cut quality and control, even in awkward cutting positions. Coupled with a 40% duty cycle at 40A and the ability to run on generators (minimum 8 kW recommended), this unit is designed to keep working as hard as you.
