Product description

The outer ring seam automatic welding machine meets the welding requirements of various welding methods of different workpieces by lifting, telescopic and walking of the cross arm. The device can be combined with the welding roller frame to form an automatic welding center, which is suitable for automatic welding of the outer ring seam of the cylindrical metal structural member, which greatly improves the welding quality and the welding work efficiency. The equipment moves along the track and consists of a trolley, a column, an electric telescopic arm, a welding power source, a wire feeding system, a swing welding torch system, and an electrical control system. The automatic welding system used in this set of work consists of the US Miller SubArc DC1250 multi-function welding power supply, RAD400 wire feeder, HDC1500DX digital welding program control box and other key configurations to form a thick wire submerged arc welding system.
