Thermacut Ex-Trafire 85HD Plasma Cutter a newly developed concept, in which all components have been optimized and perfectly coordinated, suitable for use with hand and machine torches for plate thicknesses up to 2-1/2″. High Performance Cutting Machine.
The extremely powerful Ex-Trafire 85HD plasma cutting system is the perfect solution for demanding heavy duty applications in industry and other sectors. Powered by a 400V three phase supply, it delivers clean cuts up to 25mm and achieves severance cuts up to 45mm on mild steel. The Ex-Trafire 85HD brings you impressive performance, high flexibility, and simple operation, allowing you to meet tough demands with continuous operation.
This plasma cutter is designed for ease of use, with a simple control interface with self explanatory icons. Featuring a large 4″ LCD colour display. Minimises errors and ensures consistent, high quality results every time. Built tough for heavy-duty demands, It delivers the durability and strength needed to withstand intensive, day to day use without compromise. Ideal for automated, mechanised, and manual use. Reliable operation worldwide. The 85HD Plasma Cutter features Automatic Smart Settings that adjust cutting gas, electricity, and pilot current while compensating for pressure drops. This reduces operating errors and ensuring consistently superior cutting results.
The Ex-Trafire 85HD makes light work of all electrically conductive materials, including black steel, stainless steel, aluminium, and wear-resistant hardox. This machine offers affordable and extremely cost-effective operation. With a 100% duty cycle and very high cutting speed, the HD plasma cutter offers maximum productivity for industrial users. They quickly pay for themselves, even when not in continuous use.
Features & Benefits
- Adjustable cutting current from 20-85A – Allows precise control for different materials and thicknesses, ensuring clean, accurate cuts every time.
- Industry leading duty cycle – 100 % at 85A
- Piercing cutting capacity 25mm, cutting capacity of 25mm and a maximum severance cut of 45mm+.
- Suitable for generator use – Works reliably where mains power is unavailable.
- Grid cutting – For special cutting patterns/operations. It’s one of the machine’s built-in modes alongside normal cutting.
- Gouging mode – remove unwanted material fast from a workpiece without severing the base metal.
- Marking function – It enables clear fine, deep or wide markings to be made on components and makes downstream processes much easier. The marking function uses an integrated gas-saving function and automatic gas identification.
- TCS quick change flexible torch packages – provides a setup that allows fast torch replacement while offering adaptable configurations to meet diverse welding needs.
- Uses compressed air or nitrogen (Argon for making feature) – Affordable and easy-to-source consumable, lowering operating costs compared to other gas types.

Every Ex-Trafire power supply comes with an integrated grid mode. This smart feature automatically switches between the pilot arc and main arc, eliminating the need for manual re-ignition when moving between cuts. That means faster, smoother cutting without repeatedly pressing the torch trigger. Unlike cheap plasma cutters, the Ex-Trafire includes automatic internal safety testing at start up. If an issue is detected, the system displays an error code and prevents operation until the fault is resolved. Which protects both the machine and the operator.
These HD series plasma cutters are industry 4.0 ready. Optional CAN Bus and RS 485 interfaces mean these machines are expandable and updatable to remain extremely future proof. The Ex-Trafire HD series offers powerful and reliable plasma cutting solutions designed to meet the needs of professionals. With high performance and robust construction, these plasma cutters are ideal for a wide range of applications.
This includes: Craft, DIY, and non-industrial projects – Perfect for hobbyists and home users who need precise, clean cuts. Training and education – A reliable solution for technical schools and training programs. General fabrication – Versatile tools for workshops handling various metal cutting tasks. Automotive and transportation – Suitable for vehicle repair, maintenance, and fabrication work. Structural steel work – Capable of handling complex structural fabrication. Ex-Trafire HD plasma cutter delivers precision, durability, and versatility you can rely on.
