Welding preparation is mainly to check whether the condition of the welding machine meets the work requirements. For example, check whether the fasteners of various parts of the machine are off or loose; check whether the electrical circuit connection of the whole machine is correct and reliable; check whether the hydraulic oil in the hydraulic tank is sufficient; confirm that the power supply matches the machine input requirements; whether the heating plate meets the requirements (Whether the coating is damaged); Trial operation of milling cutter and oil pump switch, etc.

 

Then put the slips of the same pipe specifications into the rack; set the heating plate temperature to the welding temperature (the welding temperature of the polyethylene pipe machine path is 200~230℃), before heating, use soft paper or cloth dipped in alcohol to wipe the heating plate Surface, but be careful not to scratch the PTFE release layer.
