The WIDOS 8000 can be used to weld pipes and fittings out of PE and PP. The WIDOS 8000 steel version is very solid and extremely torsion-resistant. Thus, it is possible to work also under heavy conditions on the construction site and in the trench. With the hydraulic unit, the right-hand clamping devices are moved and the welding force is precisely controlled. It features a pressure backup to support the welding force during cooling down and 2 quick-action couplings as well as an analogue pressure gauge for the exact indication of the pressure. Optionally also available as enclosed aggregate with junction box. The planer has a chain drive in a closed aluminum housing and automatic chip removal to the outside. The blades used are sharpened on both sides and can be used multiple times. The heating element is anti-stick coated and has an electronic temperature control and a connecting cable with CEE plug. A puller device at the basic frame prevents a sticking of the heating element to the heated pipe ends and thus enables simple handling. For the heat-protected storage of the heating element and the planer, a heat-protected box is available. The WIDOS welding machines can easily be equipped subsequently with the WIDOS SPA weld log recorders and can also be supplied in CNC-controlled version.
The extra solid steel construction of the WIDOS 8000 makes it especially resistant. It is suitable for pipes and fittings out of PE and PP from OD 450 up to OD 800 and is used in the daily rough application on the construction site and in the trench. The machine features a double clamping device with quick clamping on the fixed and on the movable side. These are guided by 2 shafts. The hydraulic cylinders are screwed next to the guide shaft for a simple and quick installation resp. disassembly for service. There are 2 flexible hoses with quick-action couplings for the connection to the hydraulic control unit. The double clamping devices are screwed to the steel pipe frame. The outer fixed clamping device can be easily dismounted by removing 3 screws in order to weld at difficult accessible places, e.g. in trenches or at branches of T-pieces. The remaining unit of three rings can be removed from the base frame and used for repair work. The WIDOS 8000 is thus a 4-ring and a 3-ring machine in one device. Smaller pipe dimensions can be clamped by means of reducer inserts depending on the pipe diameter. A lift-off device for the easy inserting and removing of the heating element and planer is available. The hydraulic slewing crane (Palfinger) can be attached to the basic machine. The so-called truck loading crane features a hydraulic double extension up to 3.10 m and may swing by appr. 325, thus being most suitable for handling heating element and planer. The slewing crane can be operated comfortably via remote control and is optionally equipped with all prescribed warning systems.
