The WIDOS Miniplast/2 is a welding machine for the heating element butt welding of PE, PP and PVDF pipes and fittings from OD 20 to OD 110. Due to its light and compact construction, the machine is ideally suited for the use in pipeline systems and for assembly work. In case of stationary use, the machine can be fixed in the vice or with the table support. The basic machine has two large aluminum basic clamping tools which are swiveling 15° on each side for the fabrication of segmented bends. By screwing in 8 small reduction clamping inserts, a double clamping is obtained at smaller diameters. For fittings with short legs, a small fitting clamping tool is available as an option. Due to the special construction of the pressure build-up device, the machine can be fixed directly at very short pipe ends on walls and sheets.
