Manual welding machine for touchless welding of pipes and fittings of OD 20 up to OD 63, based on infrared radiation and heating element butt welding by means of easy mountable anti-stick coated top plates. For the exact preparation of the weld and for the calibration of the radiation, a planer is mounted on the machine.
All movements of the machine are performed manually, are supported by a high precision linear guideway and also provided with a guidance in order to avoid collision. With respect to specific requirements in the cleanroom area, all surfaces are scuff-resistant nickel-plated, in anodized or high quality steel version. The temperature range of the heating element is electronically continuously variable up to 500°C. For that reason, in combination with a very good radiating, abrasion free surface coating, the heating element is suitable for the infrared welding of all common fluorine plastics and polyolefines.
Due to a specific arrangement, the current welding pressure is shown in Newton on the separate, portable control unit without being influenced by the drag force. For the optimal alignment of the pipes, a horizontal and vertical offset compensation is provided for an offset-free welding.
