The welding machine is designed, above all, for welding of electro-fittings without bar codes for connection of PP piping to water supply mains. The welding machine and all the necessary cables are stored in a small briefcase, where they are protected against any damage. The welding process is fully automatic, its course is shown on the display together with all potential defects which could appear during welding. The machine is controlled using three pushbuttons. If necessary, this machine can weld several fittings simultaneously.
