Butt fusion welding machine with hydraulic self-alignment suitable for welding pressure pipes for water, gas and other fluids, with diameters ranging from 75-250 mm. Built in accordance with international standards (UNI 10565, ISO 12176-1), BASIC 250 includes: -the machine body is a support frame, four clamps and two hydraulic cylinders with quick coupling connections, available with Ritmo’s patented SMARTLocK quick adaptation system, -heating plate covered with Teflon (PTFE) with a built-in thermometer, for checking the working temperature, and a high-precision Digital Dragon electronic thermoregulator (±1°C) with digital display and adjustment buttons. This system has LED indicators to verify that the machine is operating normally (voltage and working temperature), probe errors and/or temperature anomalies. -extractable electric facer for preparing pipe ends and/or fittings. Includes a safety microswitch and thermal switch. -electro-hydraulic unit mechanically and weather protected by a plastic box. Includes control lever, for opening and closing the clamps, maximum pressure and discharge valves, hydraulic connection hoses with quick couplings and timer (to verify heating and welding times). The welding machine is preset for connection of THE INSPECTOR electronic controller (which is optional) -support for facer and heating plate -BASIC 250 is capable of welding fittings, such as elbows, tees, Y branches and long construction flange ends without any adapter.
