How to put small pieces of graphite?

1. First, remove the foam protective cap on the electrode hole of the spare button graphite sheet, and check whether the internal thread of the electrode hole is complete.

2. Secondly, carefully screw the connector into the electrode hole at one end of the spare graphite electrode, so as not to collide with the thread.

3. Finally, hang the spare electrode above the electrode to be connected, align it with the electrode hole, and then slowly put it down. Tighten the spare electrode with a torque wrench until the end faces of the two electrodes are in close contact.
