Disposable cylinders for back purge?! That is going to cost you a Euro every couple of minutes!looks good- exhaust porn, I am getting meself a little backpurge system together, they don't do it round here and you can't get the take offs to run a purge line, so I got a dispo bottle reg from weldequip(only ones that are any good) a bit o gas hose and I will use a diposable bottle to purge, or I was going to, the DIY shed have stopped stocking dispo Argon bottles now, so I'll have to see if the argon mix is any use unless I can track down dispo Argon bottles somewhere.
I did a very short test with my MIG on some stainless, then welded up an exhaust for a tractor ( a farmers one-not a harley) and it went ok so its summat I will bear in mind for any future stuff.
That was using the standard gas mix for m/s MIG. I can get that in dispo bottles so I might backpurge and MIG some stuff to see what results I get.
