Functionality: The machine uses heat to melt the surfaces of pipes and fittings, allowing them to fuse together into a single, seamless, leak-proof joint that is often stronger than the pipe itself.Temperature Control: Most machines operate at a constant temperature, typically between 260°C and 280°C.Versatility: It often includes interchangeable welding heads (die heads) to accommodate various pipe diameters, such as 20mm, 25mm, and 32mm.Components: The kit usually comes in a metal carrying case and includes the heating device, a support stand, and various socket heads.
