Peculiarities of RK755-K:
In the robotic system is implemented a process of the welding in one position with simultaneous loading-unloading of workpieces in an another position.
The system is completed as a cell that protects staff from detrimental effects of welding arc and foul gases. For safety it consists of optical safety fence.
