Introduction PPR welding machines are essential for achieving durable and leak-proof connections in modern plumbing systems. While power and temperature control are often considered first, the heating plate specifications—including size, thickness, and material—are the most critical factors influencing welding quality, efficiency, and the service life of both the machine and the pipe system. Heating Plate Size: Matching Pipe Diameter and Project Scale The size of the heating plate determines the maximum pipe diameter the welding machine can handle. – Small
