Retaining Cap

The outer retaining cap essentially keeps the shield in place on top of the inner cap and also directs the shield gas towards the shield. There is a contact tab present on the outer cap that is used sometimes on THCs as an electrical contact to the work plate.

You must inspect the outer retaining cap carefully and check the following: The top opening of the cap should be completely round without any arc marks or nicks. The threads at the base of the outer cap must be clean and should not be worn out.
