this machine adopts synchronous control technique both welding time and cent-control welding is composed of plc program system with pressing firmly once only and welding repeatedly. the input front-panel has two forms: touch screen and keyboard, it makes this machine more intelligent and reasonable .the weft supplies are automatic. the greatest advantage is that you can adjust the distance of wefts at random on one piece of mesh sheet. this machine is equipped with new and efficient trans format whose gear shift has 8-class so it enlarges welding range. it is easy to learn and operate and welding output is several times and than manual work. the main parameter: wire diameter: 3-5mm welding aperture: 50*50-300*300mm width of mesh: 2000mm number of warp: 41 welding speed: 30times/min rated voltage: 380v rated electrical power: 400kva overall dimension: 6*3.2*1.8m machine weight: 3.2t
