Thermal Dynamics Cutmaster 40

Cutmaster 40 delivers more power

Flexible, lightweight new plasma cutter from ESAB’s Thermal Dynamics designed for portable applications

Thermal Dynamics, an ESAB brand, recently launched its Cutmaster 40 manual plasma cutting system, the successor to its Cutmaster 42.

The power source weighs 22 pounds, has the flexibility to use 115-volt to 230-volt primary power, and delivers a rated output of 40 amps at 40% duty-cycle or better, the company said.

On 230-volt primary, it delivers a recommended cut and pierce capacity on 1/2-inch steel and can sever steel up to 1 inch. On 115-volt primary, it delivers a recommended cut and pierce on 3/8-inch steel. To use 115-volt, connect the supplied 115-volt adapter to the hardwired 230-volt plug. The unit is designed for motor sports, mobile fabrication, light construction, HVAC, metal/building/roofing, mechanical contracting, maintenance/repair, farm/ranch, metal art and DIY applications.

“Head-to-head evaluations against leading competitors confirmed that the Cutmaster 40 delivers superior cutting performance on both 115V and 208-240V primary power,” said Kris Scherm, ESAB’s global manual plasma business and product director. “You don’t always need that extra punch of power or duty cycle, but it’s there when users need it to work harder or take on bigger jobs.”

The Cutmaster 40 features a rugged, weather-proof, three-handle case that better protects the unit, especially during transportation in a job box or back of a work truck, ESAB said. The handles make it easier to move the unit in tight quarters, as well as help organize the cables when moving it.

The Cutmaster 40 comes with the proven SL60 1Torch with 16-foot torch lead, which is up to 4 feet longer than competitive torches. Further, because it uses Thermal Dynamic’s ATC torch connection (standard on all Cutmaster units), users can connect an additional 25-foot length of torch lead or the SL60QD 1Torchâ, which offers a quick disconnect feature enabling selective replacement of either the torch handle assembly or torch leads at a lower cost than replacing both together (a necessity with one-piece torch/lead assemblies). The work cable uses a standard 50-milimeter Dinse connection, while the robust work clamp creates a strong electrical connection.

“We designed the torch and work cables to disconnect in seconds, which improves cable management when moving the unit,” Scherm said. “Also, because these items are often used in tough industrial environments, things can be damaged, so the quick disconnect design makes them easily replaceable.”

The SL60 1Torch comes with the Cutmaster Black Series electrodes, which extend operating life by up to 60%. As a result, they lower cutting cost and downtime, as well as maintain cut performance over a longer time period, the company claimed.

ESAB backs the Cutmaster 40 with a four-year warranty on the power supply and one-year warranty on the 1Torch.
