If you're looking for a reliable and efficient plasma cutting machine, then the Thermal Dynamics Cutmaster 30+ is definitely worth considering. This compact and lightweight cutter is designed to deliver professional-level performance in a portable package, making it ideal for DIY enthusiasts, light metal fabricators, and small workshops.

What makes the Thermal Dynamics Cutmaster 30+ stand out?

Cutting Performance

The Cutmaster 30+ boasts a maximum cutting capacity of 5/8 inch, which means it can easily slice through a wide range of metals, including steel, stainless steel, and aluminum. It has a recommended cutting capacity of 3/8 inch but can cut up to 5/8 at slower speeds. There is a possibility it can cut up to 3/4 of an inch but that is not something you would want to consistently do with this unit.

Power and Efficiency

The Cutmaster 30+ runs on 120V or 240V power, which means you can use it in any standard power outlet. It also features Thermal Dynamics' patented "SureLok" technology, which ensures that the torch consumables stays securely in place during cutting, improving consistency and cut quality. The consumables the 30+ uses also last longer. They are the black series extended life electrodes, that can last up to 60% longer than standard electrodes. This cutter also packs the power to keep going all day with a 40% duty cycle at 30 A and 100% duty cycle at 20 A.

Weighing in at just 24 pounds, the Cutmaster 30+ is easy to move around, making it a great option for mobile workshops or job sites. It also features integrated carrying handles, which makes it easy to transport from one location to another. 


The Cutmaster 30+ comes with a range of accessories, including a 10-foot torch lead, a power supply cord, and a 13-foot work cable and clamp. It also supports a variety of torch styles, including hand-held, mechanized, and automated options, making it a versatile machine that can be used in a range of cutting applications.

Ease of Use

This machine was designed with the user in mind, with a clear and easy-to-read front display. The new Cutmaster features a 4.3inch digital screen that displays crucial information and allows you to make quick adjustments. It displays the amperage and the psi, whether you are cutting expanded or sheet metal, and gives you the option to adjust the trigger. The screen also eliminates all of those pesky error codes and will show you a graphic of the issue at hand.

The picture below is an example of a new error code. In this example the consumable is too loose. The machine detects that and displays a graphic, instead of the old style error codes.

Whether you're a hobbyist or a light metal fabricator, this machine has everything you need to get the job done quickly and easily.

If you are looking for a Thermal Dynamics plasma cutter that can cut thicker than the 30+, there are a few options. The Cutmaster 40 is recommended to cut up 1/2 inch and can cut up to 1 inch. The Cutmaster 60i is recommended to cut 3/4 inch and can cut up to 1.5 inches.
