Heating element butt welding machine in steel version for pipes and fittings made of polyolefines from OD 315 to OD 630 mm (WIDOS 6100 steel version), OD 450 to OD 800 mm (WIDOS 8000), OD 500 to OD 1000 mm (WIDOS 10000), OD 710 to OD 1200 mm (WIDOS 12000), OD 1000 to OD 1600 mm (WIDOS 16000) and OD 1400 to OD 2000 (WIDOS 20000). For the use on building sites and in trenches.
The welding machine has a double clamping system on both the tight and movable side that are placed on two guiding shafts. For an easy and fast erection resp. dismantling upon maintaining, the hydraulic cylinders are screwed next to the guiding shaft. Two flexible hoses with quick-action couplings enable the connection to the hydraulic controlling device. The double clamping tools are screwed to the steel pipe sub-construction. The external tight clamping tool can be easily dismantled by removing seven screws in order to weld at difficult accessible places like trenches or at branches of T-pieces.
The electric hydraulic unit for the movement of the right double clamping device and for the exact control of the welding forces has a post-pressure facility to support these forces while cooling down and two quick-action couplings. The planer is fixed to the guiding shafts, has a chain drive in a closed aluminium housing with a gear motor and an automatic chip removal. The heating element is fixed to the guidings shafts, anti-stick coated, has an electronic temperature control with digital display, controlling lamps, an on/off-switch and a connecting cable with shock-proof plug. The separation device prevents the heating element from sticking to the pipe after the heating process.
For the heat-protected storage of the heating element and the planer, a reception box is available. 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 the planer is available. All components are covered by the WIDOS works warranty.
The WIDOS plastic welding machine can easily be retrofitted with the WIDOS SPA weld log recorder and can also be supplied in CNC controlled version. The WIDOS welding machine has a voltage of 400 V. Other voltages on request.
