The extra solid steel construction of the WIDOS heating element butt welding machines makes them particularly resistant. They are for pipes and fittings out of PE, PP, PA and PVDF from OD 710 to OD 1200 and are used in the daily rough application on building sites and in trenches.
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. For an easy and fast erection resp. dismantling upon maintaining, the hydraulic cylinders are screwed next to the guiding shaft. There are 2 flexible hoses with quick-action couplings located at the machines enable the connection to the hydraulic controlling device. The double clamping devices are screwed to the steel pipe frame. The outer fixed clamping device can be easily dismounted by removing only a few screws in order to weld at difficult accessible places, e.g. in trenches or at branches of T-pieces.
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 an analogue pressure gauge for the exact indication of the pressure. Optionally also available as enclosed aggregate with power distribution board.
The WI-CUTTING® planers are suspended from the guide shafts, have a chain drive in a closed aluminium housing, a micro safety switch 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 fixed to the guiding shafts, are anti-stick coated, have electronic temperature controls, controlling lamps, an on/off-switch and a connecting cable with shock-proof plug. The pullers for the heating elements prevent a sticking to the pipe after heating-up. 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. Lift-off devices for the easy inserting and removing of the heating elements and the planers are 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 WIDOS machines are operated at voltages of 400 V. Other voltages on request.
