An Electrofusion Welder is a specialized tool used in the process of joining plastic pipes and fittings, commonly in industries like construction, water distribution, and gas systems. The welder utilizes an electric current to heat a metal coil embedded within a fitting, causing it to melt and fuse with the pipe, creating a strong, seamless connection. This method is particularly advantageous for its precision, ease of use, and reliability, ensuring leak-proof, durable joints without the need for external heat sources or complicated equipment. Electrofusion welding is ideal for installing pipes in hard-to-reach areas, offering a faster and more efficient alternative to traditional welding techniques.
