The Lincoln Electric FlexCut 35 is the entry point in Lincoln Electric’s newest generation of portable plasma cutters, replacing the older Tomahawk series with a more modern platform built for cleaner cuts, easier setup, and better everyday usability.
With 35 amps of cutting power, dual-voltage input, and a 100% duty cycle at rated output, the FlexCut 35 is designed for light fabrication, HVAC work, maintenance, and general shop cutting on mild steel, stainless steel, and aluminum up to 1/2 in. thick.
The FlexCut 35 runs on either 120V or 230V single-phase input, giving you the freedom to cut from a standard household or job-site circuit or step up to 230V when you need full performance in the shop.
On 120V, it is ideal for service work and mobile cutting applications where 230V is not available. On 230V, it delivers full 35-amp output with the duty cycle needed for steady production work.
A bright LCD display and simple control layout make setup fast and intuitive. Operators can quickly adjust amperage, choose cutting modes, and use guided setup features to match settings to material type and thickness.
This makes the machine easier to use for both experienced fabricators and newer plasma cutter operators who want reliable results without wasting time on setup.
The FlexCut 35 is built around Lincoln Electric’s FlexConnect torch platform, which allows quick replacement of torch components and gives users access to a broader range of compatible torch configurations and accessories.
That added flexibility helps reduce replacement cost over time and gives shops more options as their cutting needs change.
This machine is well suited for sheet metal cutting, small fabrication jobs, maintenance work, and general repair applications. Its compact design makes it easy to move around the shop or take to the job site without giving up the power needed for real cutting work.
For contractors, school welding programs, farm repair, and small fab shops, the FlexCut 35 offers a strong balance of portability, output, and ease of use.

The Lincoln Electric FlexCut 35 Air delivers reliable 35-amp plasma cutting performance in a compact, self-contained machine with a built-in air compressor. That means you can start cutting without needing shop air, making it an excellent choice for mobile work, light fabrication, and field repairs.
Designed for portability and simple operation, the FlexCut 35 Air combines dual-voltage input, guided digital controls, and dependable cut quality in one machine that is ready to work wherever power is available.
The biggest advantage of the FlexCut 35 Air is its integrated air supply. By eliminating the need for an external compressor in many situations, it reduces setup time, improves portability, and makes the machine much easier to use on job sites, in maintenance departments, and in mobile service applications.
This self-contained design is especially useful for contractors, HVAC installers, demolition crews, rental fleets, and anyone who needs plasma cutting capability in locations where shop air is not practical.
The machine features an LCD user interface with clear controls for amperage, process selection, air source adjustment, gas purge, and guided cutting setup.
Operators can enter material type and thickness, then view the recommended cutting amperage for cleaner, more consistent results with less guesswork.
The FlexCut 35 Air is compact enough to carry easily, yet rugged enough for real working conditions. Its industrial IP23S protection helps resist dust and water spray, making it better suited for field use than many light-duty plasma cutters.
Whether you are cutting in a shop, on a construction site, or at a service call, the machine is built to give you dependable performance in a wide range of environments.
Lincoln designed the FlexCut 35 Air with long-life consumables and optimized airflow to help increase cut life and lower operating cost. The threadless electrode connection and snap-in consumable design also make replacements quicker and easier.
That means less downtime, easier maintenance, and faster turnaround when consumables need to be changed.
