A cutting edge electrode (tear-seal electrode) has a sharp cutting edge adjacent to the welding tool edge along the length of the electrode. With this type of tool it is possible to simultaneously weld and cut the material. This makes it easy to tear off waste material from the product after the welding process is finished. The cutting edge electrode works for thin materials – all non-woven types and some woven types. For a cutting edge electrode to work with a woven material, the cloth inside the material has to melt when exposed to HF.
A cutting edge electrode is very useful when welding for example stretch ceilings, cinema screen, inflatable products and rainwear.
