Can be retro-fitted with SPA weld log recorder
CNC version available
The Widos Type 4900 is a butt welding machine for PE and PP pipes and fittings that has been designed for rugged use on construction sites and in trenches.
The machine has a double clamping device with quick clamping on the fixed and on the movable side guided by two hydraulic cylinders. There are two flexible hoses with quick-action couplings for connection to the hydraulic control unit. The double clamping devices are screwed to the steel pipe frame. The outer fixed clamping tool can be easily dismounted to enable welding in places of poor accessability.
The electro-hydraulic unit (for moving the right-hand clamping device and for the exact control of the welding forces) has a pressure backup for supporting the welding force during the cooling period, two quick-action couplings as well as a digital pressure group.
The planer is suspended in the guid shafts, has a chain drive in a closed aluminium housing, a security micro switch with lock and an automatic external chip removal.
The heating element is suspended in the guide shafts and is anti-stick coated. It has an electronic temperature control wth digital display, control lamps, and on/off switch and a connection cable with shock-proof plug. The heat-separating device prevents the heating element from sticking to the pipe after the heating process.
The Widos 4900 welding machine can easily be retrofitted with the Widos SPA weld log recorder and can also be supplied in a CNC controlled version. Automatic movement of the heating element is also an option. The machines are supplied with a transportation case and are available for use with a 110v or 230v power supply.
Widos, established in 1967 manufactures a comprehensive range of socket and butt welding machines from simple hand held devices to sophisticated CNC equipment for large diameter piping projects.
