Shifter is a special welding auxiliary equipment for reverse work welding offset to achieve the desired processing position and welding speed. It can be combined with work machine and welder to form a group of work stations, forming a semi-active welding center, and can also be used to move the workpiece during manual work. When the worktable rotates, it adopts the frequency converter to adjust the speed steplessly with high precision. The remote sensing box can successfully complete the long-distance operation of the working table, and can also be connected with the control system of the working machine and the welding machine to successfully complete the linkage operation.Welding has been made easier with the advent of welding displacements, which can be used not only for automatic welding, but also for manual welding. Not all workpieces are small. Welding is difficult with many large workpieces at the wrong angle. Shifter has the function of workpiece support and transposition, welding shifter changes the angle of the welded workpiece.
