The magnet for ground cable with detachable magnetic field is a solution that enables a quick and easy attachment of the grounding cable (and not only) to a welding machine. The magnetic fasten and appropriate preparation of the workpiece allows its easy fixing to any surface (surface, roll, etc.). The copper connector stud allows the cable to rotate about the axis, and increases the conductivity of the current. The magnet is available in two versions: for 300A and 500A.
