Thermacut EX-TRAFIRE® 45SD Plasma Cutter

Professional 45 Amp Plasma Cutting System

The Thermacut EX-TRAFIRE® 45SD is a professional, compact and portable plasma cutting system designed for demanding fabrication, engineering, maintenance and workshop applications.

With a maximum cutting current of 45 amps, the EX-TRAFIRE 45SD delivers reliable plasma cutting performance across a wide range of electrically conductive materials. The system supports cutting, gouging and grid cutting, making it a versatile addition to both professional workshops and CNC plasma cutting applications.

The EX-TRAFIRE 45SD is available in configurations for 230V single-phase and 400V three-phase operation, with a built-in CNC interface for connection to compatible CNC plasma cutting tables. Thermacut specifies compressed air or nitrogen as the plasma gas.

Ideal for Manual & CNC Plasma Cutting

The EX-TRAFIRE 45SD has been designed to work with both hand and machine torches, making it suitable for conventional handheld plasma cutting as well as automated CNC applications.

The integrated CNC interface and 50:1 voltage divider make the machine particularly useful for CNC plasma table installations where accurate torch height control is required.

Excellent Cutting Capacity

On the 230V single-phase version, Thermacut specifies a recommended cutting capacity of up to 12mm, a piercing capacity of up to 10mm and a severance capacity of up to 25mm on low-alloy/mild steel. Actual cutting performance will depend on material type, thickness, condition, cutting speed and consumable condition.

Compact & Portable

At just 12.7kg, the EX-TRAFIRE 45SD is easy to move around the workshop or transport to different jobs. Its compact dimensions of approximately 469 × 228 × 177mm make it an excellent choice where space and portability are important.

Duty Cycle

The EX-TRAFIRE 45SD provides a 50% duty cycle at 45A on 230V single phase, increasing to 100% at 32A.

The three-phase version provides an even higher duty cycle of 80% at 45A and 100% at 40A, making the three-phase configuration particularly suitable for applications requiring extended periods of plasma cutting.

EX-TRAFIRE® 45SD Consumables

Keeping your plasma torch fitted with good-quality consumables is essential for maintaining consistent cutting performance.

We supply Thermacut EX-TRAFIRE 45SD consumables for the FHT-EX®45TTH and FHT-EX®45TTM torch systems, including replacement wear parts for routine maintenance.

Depending on the torch configuration, consumables include components such as:

Electrodes
Cutting nozzles
Shield caps
Swirl rings
Other replacement torch components

Regularly checking and replacing worn consumables can help maintain cut quality, improve consumable life and reduce unnecessary downtime.
