20mm - 1000mm Proxima EF Fusion Welder Hire HDPE Electrofusion Welder This 40v fusion machine is designed specifically for quickly and efficiently connecting all major MDPE electro-fusion fittings. It uses the extreme heat and pressure produced during welding to make simple, reliable, rigid joints between pipes. The heat required to make the joint comes from flowing a constant electrical current through the embedded heater wires within the sleeve fitting, which is placed around the two pipes. The pressure required to make the joint is obtained via the shrinking of the fitting under welding conditions. The shrinking process does not alter the internal bore of the joint because the ends and the centre of the fitting are deliberately kept cold during the welding process. This ensures a strong, reliable professional joint. Once the joint is completed, the heater wires remain encased in the MDPE so there is no chance of corrosion. The connecting sleeve fitting must be fitted evenly between both pipes and the pipes must have clean cut, straight, burr-free edges to provide the most reliable, long-lasting joint. This electrofusion welder gives you functionality, reliability, and affordability and is capable of welding all brands of fittings between 20mm and 1000mm. It features a protective hard case, automatic fitting recognition, barcode scanning, and manual data entry options for ease of use. Ergonomically designed to sit on large diameter pipes, a large display and keypad, as well as a host of other features, will guarantee to satisfy the needs of the modern welding professional.
