Heating element butt welding machines for pipes and fittings out of PE, PP, PA and PVDF from OD 200 to OD 450 for the use on building sites and in trenches.
Maximum force 1414 daN at 100 bar, maximum working pressure appr. 120 bar.
The WI-PRECISION® machines have 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.
With the WI-FORCE® 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 WI-CUTTING® planers are suspended from the guide shafts, have a chain drive in a closed aluminum housing, a micro safety switch, a lock for the safe operation of the planer and an automatic external chip removal. The planer knives used are sharpened on both sides and can be used multiple times.
The WI-HEAT® heating elements are suspended from the guide shafts, are anti-stick coated, have an electronic temperature control with digital display, control lamps, an on/off-switch and a connecting cable with shock-proof plug. For the heat-protected storage of the heating elements and the planers, heat-protected boxes are available.
Smaller pipe dimensions can be clamped by means of WI-FIX® reducer inserts depending on the pipe diameter. In addition large reducer inserts or a combination of small and large inserts can be delivered.
The WIDOS welding machines can easily be equipped subsequently with the WIDOS SPA weld log recorder and can also be supplied in CNC-controlled version.
The WIDOS machines are operated at voltages of 230 V. Other voltages and heating elements moving out automatically on request.
