Important: The hot knife cutter HWS250 is intended for short-term use. If the cutter is operated continuously for a long time, it can result in transformer failure and excessive bending of the cutting blade. 



The bendable blade Type-G30 is used as a cutting element for grooving platforms. The blade has a medium level of elasticity and may be bent without special tools. The desired shape (for example, a semicircle with different diameters for cutting grooves for tubes) can be changed by hand or by using whatever tools are available. Use pliers for straight rectangular or angular bends. The flexible blade Type-G30 is 30 cm long and 5 mm wide.

The grooving platform “Groover” works only with the shaped blade Type-G30. The Type-G30 blade bent into the desired shape is fixed in special width adjustable holders, which can also be used to adjust the height of the blade.


The grooving platform “Groover” is equipped with detachable guide rails which can be adjusted over the entire width of the platform. You can use one or two rails or remove them completely by unscrewing the fixing bolts. The allen key is attached to the top of the platform for fast installation of the grooving platform on the hot knife cutter.


The tube seat groover (grooving “MINI” platform) works only with the shaped blade Type-G30. Unlike the more advanced model (grooving platform), the MINI platform is primarily used for cutting small grooves, grooves for different tubes or, for example, for fittings. The height of the blade can be adjusted.



The adapter for straight blades “Cutting guide” helps cut expanded polystyrene evenly and at different angles. The adapter is fixed with two bolts to the base of the hot knife cutter and is generally used with standard straight blades Type-D20 (L = 200 mm) and Type-D25 (L = 250 mm). The adapter is fitted with an adjustable guide bar with a back stop and an angle adjuster.

Important: When using optional accessories, always take into account the length of the blade fixed in the holders of the platforms and choose/adjust the correct blade heating cycle. To do this, follow these steps:

  • Set the step-by-step power controller to the minimum value.
  • Fix the blade to the platform holders.
  • Activate the cutter by holding down the power button (switch)
  • Touch the material with the blade.
  • Turn the step-by-step power controller until the blade starts to cut the material smoothly. Note that it takes 3 to 5 seconds for the blade to heat to the value set on the controller.
  • When the right value is set, you can now start working.
