If you've got a meter, test it but I think you'll find the case is isolated, so you'll need to connect the earth lead to it in order to weld it. Should be OK. If not, well, another SIP bites the dirt! :))
Read the full replyOn 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.
