1-4200-SL60 - Thermal Dynamics Cutmaster 42 Plasma System with SL60 Torch

Professional Grade Portability with the Cutmaster 42

The Thermal Dynamics Cutmaster 42 Plasma Cutter represents a significant leap in portable plasma cutting technology. Designed for professionals in auto body, marine repair, plumbing, and HVAC, this unit bridges the gap between lightweight portability and heavy-duty performance. Weighing in at only 26 lbs (11.8 kg), the Cutmaster 42 is housed in a rugged case designed to withstand the rigors of daily transport and job site use.

One of the most distinct engineering choices in the Cutmaster 42 is the inclusion of the SL60 1Torch. While most machines in this amperage class utilize smaller, less durable torches, Thermal Dynamics has equipped this unit with the same torch found on their larger 60-amp and 80-amp systems. This provides users with superior arc stability, longer consumable life, and the ability to perform plasma gouging—a feature rarely found in compact 40-amp cutters.

Dual Voltage Versatility

Flexibility is key for mobile fabrication. The Cutmaster 42 features intelligent dual-voltage technology, allowing it to operate on standard 120V household power or 230V industrial power. When connected to 120V, the machine delivers a respectable 27 Amps, perfect for light fabrication and sheet metal work. When switched to 230V, the output jumps to a full 40 Amps, providing the power to cut up to 5/8 inch (15 mm) mild steel and sever even thicker materials.

Vent2Shield Technology

Air supply is often a bottleneck for portable plasma cutting. The Cutmaster 42 utilizes Vent2Shield technology, which optimizes air flow and pressure requirements. This allows the unit to operate effectively with considerably smaller air compressors compared to similar 40-amp units, making it an excellent choice for service trucks and workshops with limited air capacity.
