Heating Phase The PPR fusion welder heats its welding mold via built-in high-efficiency electric heating elements (e.g., ceramic heating tubes).Mold temperature is the most critical parameter for welding quality, typically set between 200°C – 400°C. This must be strictly calibrated based on the PPR material grade, pipe dimensions, and environmental conditions. Precision Temperature Control (Core Technology):Modern high-performance PPR fusion welding machines universally adopt closed-loop temperature control systems, including: Melting Phase Clean PPR pipe ends and fitting sockets are inserted vertically and without rotation into the heated mold (equipped with
