This machine adopts electrical syn-chronous control technique, both welding time and cent-control welding is composed of digital and integrated electriccircuit. This operation is accurate, it has stable function, firm welded point and without welded tracks. Not only welding speed is fast but also it is easy to learn and operate. Step motor controls fallen wefts structure and drawing materials are automatic, so it is even and accurate the edge of mesh is regular, it is unnecessary to slice the side. Drawing mesh adopts the device with the elastic tension link and fixing mesh, it is easy to regulate mesh hole and mesh size is rather accurate, welding aperature could also adjust randomly within range. The main parameter: Wire diameter: 1.8-3.5 mm Welding aperture: 50*50-200*200mm Width of mesh: 1200mm Number of warp: 25 Welding speed: 45times/min Rated voltage: 380V Rated electrical power: 189KVA Overall dimension: 1.8*2.5*1.8m Machine weight: 3.2T
