I got my Power i-TIG 200T going.

The negative dinse connector in the machine seems to have, "normal" fit and everything snugs up in it at around a quarter turn and locks in.

The positive dinse connector has a much looser fit.

Nothing starts to tighten up until past a half a turn and seems to stay, but doesn't seem very secure or locked in.

is this normal?

Is there that much variation in connectors or is the positive one looser than it should be?
