The PTFE tapes (Teflon tapes) lie over the welding wire and prevent the hot polymer from sticking to the welding jaws during the welding process. The non-stick effect of the Teflon begins to degrade after approx. 1,500 welds. To maintain the quality of the weld seams, both tapes must be replaced. You can easily change them yourself. Made in Germany.

Material: Polytetrafluoroethylene (PTFE)
