On my cheapo sip migmate the captive nut in the casing for holding the lid on has come loose - I would weld it back on, but is it ok to weld the case of the welder using the welder itself or would I damage it? (I'm thinking that the mig case is earthed, so running the electrically isolated dc welding current across it would be fine, but would like to check before I fry it!).

Rivnut maybee?
On my Lincoln MIG welder, I was replacing the wire when a loop from the spool fall behind the reel and I also accidently hit the weld trigger-- the wire welded itself to the reel nut.
It only happened for a second. The welder seems to be fine. Now I'm a lot more careful when replacing wire spools- I shut off the welder.
So, I would imagine that welding to itself works but I wouldn't trust frying something.
