Which component of a spot welding system remains stationary during operation?

Explanation:
In spot welding, two electrodes work together to form the weld, with one arm staying fixed to provide a stable base and alignment while the other arm moves to clamp the pieces and deliver the welding current. The arm that remains stationary serves as the anchor, so the joint forms at the correct location and the weld remains consistent. The moving arm is the part that travels during the weld cycle to apply pressure and current. The power switch and control indicator are controls and do not participate in the mechanical clamping during operation.
