A hydraulic self-aligning butt fusion welding machine suitable for welding pressure pipes for water, gas, and other fluids, with diameters ranging from 40 to 160 mm. Built according to international standards (UNI 10565, ISO 12176-1), the BASIC 160 includes: – The machine body, a support frame, incorporating four jaws/clamps and two hydraulic cylinders with quick-release couplings. – A Teflon (PTFE) coated heating plate with a built-in thermometer for checking the working temperature, and a high-precision Digital Dragon electronic thermoregulator (±1 °C) with a digital display and adjustment buttons. This system features LED indicators to verify normal operation (voltage and working temperature), probe errors, and/or temperature anomalies. – An extractable electric facer for preparing pipe ends and/or fittings. It includes a safety micro-switch and a thermal circuit breaker. – An electro-hydraulic unit mechanically and weather-protected by a plastic box. It includes a control lever for opening and closing the jaws, maximum pressure and discharge valves, hydraulic connection hoses with quick couplings, and a timer (to check heating and welding times). The welding machine is preset for connecting the optional THE INSPECTOR electronic controller. – A support for the facer and heating plate. – The BASIC 160 is capable of welding fittings such as elbows, tees, Y-branches, and flange necks without any adapters. Technical specifications: – Materials: HDPE, PP, PP-R. – Operating range: 40 – 160 mm. -Power supply: 230V. – Maximum absorbed power: 2250 W. – Operating temperature: 180 – 280 °C. – Operating pressure: 0 – 150 bar. – Ambient temperature: -10 – 40 °C. – Time to reach welding temperature: less than 20 minutes. – Machine body dimensions: 606 x 365 x 375 mm. – Body/standard structure weight: 32/77 kg. – Required generator power: 3.5 – 4 kVA.
