The temperature and the time depend on the particular manufacturers’ indications and can be scanned, for instance, via a barcode that is fixed at a fitting and automatically set by the welding device.

The welding pressure is determined by the fitting ratio of the pipe diameter to the heated coil connector and results from the volume increase of the polyethylene fuse material between the pipe and the heated coil connector.
