This series of gantry submerged arc welder are mainly used for automatic submerged are welding of H type steel,and it can weld the ship type position for two H type steel at the same time. This machine has automatic bi-direction arc-guiding device and automatic flux feeding and recovering device. The automatic bi-direction are-guiding device,fulling considering the actual demanding of welding,as the only one user of straight line rail in the country, has a highly tracking accuracy, small volume,and it can dynamically track the welding seam and realize the bi-direction welding to ensure the quality and improve the efficiency(generally, the arc-guiding structure of the other co***nies will cause 200mm before and after the welding seam can't be welded, but our co***ny only about 60mm). The automatic flux feeding and recovering device can reduce the cost and labour intensity of workers to improve work efficiency, and the manual welding and semi-automatic welding equipment cannot beat this. The trolley is driven by AC frequency conversion motor for stepless speed regulation and stable travel. The welding power source adopts DC-1000 arc welding power source imitating Lincoln co***ny's, with the main body produced by Chengdu Lijia welding, the MZ9 type wire feed welding head with three proprietry patents, and digital display welding controller KZ-3,ect.to ensure the quality and stability. In addition, our co***ny can also supply single welding head two wire single power source and single welding head two wire two power source(one AC and one DC)gantry H type steel automatic welder, with a high welding deposition efficiency,and the efficiency is 70% higher than using single wire, and the surface of welding seam is more beautiful.
