Heating element butt welding machine for pipes and fittings made of polyolefine from OD 50 to OD 160 mm (WIDOS 4400), OD 75 to OD 250 mm (WIDOS 4600) and OD 90 to OD 315 mm (WIDOS 4900) for use on building sites and in trenches.
The welding machine has a double clamping device with quick clamping on the fixed and on the movable side guided by 2 hydraulic cylinders. There are 2 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 by removing 3 screws in order to be able to weld at badly accessible places, e.g. in trenches or at branches of T-pieces. The remaining unit of three rings can be removed from the frame for use of repair work. The electric 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 down, 2 quick-action couplings as well as a digital pressure gauge for the exact indication of the pressure.
The planer is suspended in the guide 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 anti-stick coated, has an electronical temperature control with digital display, control lamps, an on/off switch and a connection cable with shock-proof plug. The separating device prevents the heating element from sticking to the pipe after the heating process.
For the heat-protected storage of planer and heating element, a reception box is available. Smaller pipe dimensions can be clamped by means of reducer inserts depending on the pipe diameter. In addition, large and extra large reducer inserts or a combination of small, large and extra large inserts can be delivered.
All components are covered by the WIDOS works warranty.
The WIDOS 4400, WIDOS 4600 and WIDOS 4900 plastic welding machines can easily be retrofitted with the WIDOS SPA weld log recorder and can also be supplied in CNC controlled version.
The WIDOS 4400, WIDOS 4600 and WIDOS 4900 have a voltage of 230 Volt. Other voltages on request. Heating elements moving out automatically are also available on request.
