pe pipe welder butt fusion welding machine technology
Check whether the power cord of the welding machine is complete and ensure good contact; check whether the temperature adjustment button is sensitive and effective. Clean the die head to ensure that there is no paint (coating), dust and welding slag on the die head. The temperature of the welding machine is determined according to the comprehensive factors such as temperature and wind speed at the construction site.
It is generally set to 260±5℃, and it can be appropriately increased by 5-15℃ in winter, in the wild, and windy weather. When using the whole tube, cut off the front end 3-5cm (pollution and damage mostly occur within this distance). If you find white marks on the cutting edge in a fixed direction during cutting, cut a few more knives until the color of the knife edge is basically the same (ppr pipe Longitudinal fissure generally occurs from the inner wall outwards). Clean the outer wall of the pipe and the inner wall of the fittings to ensure that there is no oil, dust and water stains (anhydrous alcohol is recommended, and high-quality paper that does not drop paper scraps is generally used in home furnishings). Mark the welding size on the outer wall of the pipe from the cut position: de20 is 14mm, de25 is 16mm, and the welding operation starts when the temperature of the welder reaches the set value and remains stable.
