Thermacut® created its own range of plasma power supplies called EX‑TRAFIRE®. Unique in their design, they are all powerful, versatile, easy to operate, durable and portable.
The EX-TRAFIRE® brand is a professional range of plasma power supplies suitable for cutting metal sheets. The power supplies are fully applicable for use in industry, small production operations and workshops. They can also be used in art.
EX-TRAFIRE® plasma power supplies engineered by Thermacut® have a wide range of advantages we are very proud of. Power supplies and torches are designed to meet the highest quality standards and provide optimal cut quality and speed.

CRITERIA FOR SELECTING A SUITABLE PLASMA POWER SUPPLY
As in the case of many other tools and devices, it is important to choose the correct type of plasma power supply for material cutting. When selecting a suitable power supply, it is important to consider several key criteria.
* First of all, consider whether you need the plasma power supply for manual cutting or machine operation. * The most common type of material to be cut is the second criterion. For example, black steel, aluminum, stainless steel, hard ox etc. * The third criterion is the anticipated continuous working time of the power supply, called duty cycle. * Last but not least, you need to consider the thickness of cut material.

Integrated grid mode
All our power sources feature an integrated GRID mode, which means automatic switching between the pilot arc and the main arc. There is no need to push a switch to turn on the main arc again when the torch is positioned to cut the material.
Higher power source output
For example, thanks to their “extraboost” feature, the EX-TRAFIRE® 75 and 100SD plasma sources can supply input torch voltages up to the value of 220 VDC. The higher the voltage between the electrode and the cut material, the longer the arc will run without being extinguished or switched to the pilot arc. This enables cutting in hard-to-reach areas and cutting material of greater thickness than with power supplies from competing suppliers.
100% Duty cycle
The duty cycle (DZ) of a plasma power supply is one of the basic parameters that expresses the ratio of maximum possible cutting time to the total working time without any power supply overheating.
EX-TRAFIRE®75SD features 100% duty cycle, which makes it a flagship not only among our power supplies but even among competing power supplies. They usually feature only 80% duty cycle at full power.
Our power supplies are considerably lighter than competing power supplies. The EX-TRAFIRE®75SD weighs only 24 kgs!
The EX-TRAFIRE® power supplies feature many safety elements. The most important is self-check after system start-up. Torch safety elements also include a “Cap sensor”, checking for short-circuits between parts, checking for torch switch pressed when the power supply is turned on, etc.
EX-TRAFIRE®75SD and 100SD offer a gouging feature. It is used for material preparation before welding and removal of defects or old welds.
Easy manual set-up
The operator can set his own cutting parameters using the rotary switch.
Quick and easy assembly
The assembly of the power supply is quick and easy thanks to the patented Torch Connection System (TCS).
