Manual butt welding machines are characterized by their simple design and excellent price-performance ratio. The operator should be familiar with the butt welding process to achieve the best possible welding result. All ZHCB type machines offer the option of logging for butt welding according to DVS 2207 and operating assistance through our external data logger RZEN 2000. The data logger simplifies machine operation and guides the operator step-by-step through the welding process. The basic frame of the ZHCB machines is identical to that of Widos butt welding machines. And because our butt welding machines are so convincing, they now come with a 30-day money-back guarantee!
