OD 50 up to OD 160 mm | construction site | PE, PP, PVDF | butt welding | manual, weld log recording, CNC
Are you looking for a heating element butt welding machine for the use on the construction site and in the trench for pipes and fittings from OD 50 up to OD 160? Then, the WIDOS 4400 is the correct machine for you.
The WIDOS 4400 can be used to process pipes and fittings out of PE, PP, PA and PVDF from OD 50 up to OD 160. The WIDOS 4400 features a double clamping device with quick clamping on the fixed and on the movable side. These are guided by 2 shafts. 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 4400 is thus a 4-ring and a 3-ring machine in one device.

The remaining unit of three rings can be removed from the base frame and used for repair work. A puller device at the basic frame prevents a sticking of the heating element to the heated pipe ends and thus enables simple handling. With the hydraulic units the right-hand clamping devices are moved and the welding force is precisely controlled. They have a pressure backup to support the welding force during cooling down and 2 quick-action couplings as well as a digital pressure gauge for the exact indication of the pressure. The planer has a chain drive in a closed aluminum housing. 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 with digital display. 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.
