This equipment is designed to weld electrofusion fittings suitable for low pressure PE pipe work systems from 32mm to 315mm diameter. The welding output of this equipment is a controlled current of 5A or 10A and a controlled voltage of 220V. It has been designed to operate on a 110V supply and has been made in a small lightweight plastic case making it easy to carry and protecting it from harsh construction site conditions. It can weld fittings commonly made by Geberit, Wavin, Valsir, Polypipe and Akatherm which are used for siphonic rainwater and waste water applications.
