Welding in cold weather is not simply a temperature problem—it directly affects fusion quality, heating stability and joint durability. For industries using PPR, HDPE, PP-RCT, PE-RT and industrial plastic pipe systems, low temperatures can lead to brittle failures, incomplete melting, moisture contamination and unnecessary rework. That’s why thicker fusion welding machines, also referred to as heavy-duty cold-weather PPR welding equipment, are widely preferred by professional installers and contractors working in winter and outdoor environments. Unlike standard lightweight welders, thicker fusion
