This equipment is mainly used for inner wall cladding of valve bodies, flanges, and pipe fittings in the oil & gas industry. The workpiece is placed horizontally, and the operator selects the workpiece program, sets parameters, and inputs welding data. Once the arc starts, the welding process runs automatically. The system uses an ETR infinite-rotation welding gun, allowing continuous circumferential rotation and eliminating dead angles caused by limited swing in traditional welding. It offers strong welding performance and supports various surface types: circles, gradient diameters, flat circles, valve intersections, circular and square tracks, V-grooves, and different pipe diameters.<br> Key Features:<br> 1.360° unlimited rotation, stable 500A current transmission <br> 2.Welds Φ40-Φ1800mm workpieces, max depth 1300mm with extension <br> 3.Intelligent control with 1-click welding, bilingual touchscreen <br> 4.Precision mechanics: 3000mm beam stroke, ±0.1mm axis accuracy<br> 5.Integrates Fronius power, water cooling & safety devices for efficiency
