noob to tig, I just got a 90 amp tig inverter as a gift from a friend.

I don't know how to use this thing, but I really want to learn. I have been reading the threads and find some of the welding terms that I am not sure what it is.

Back-purge, what process is that?

I saw a post on fusion welding pipes, so no filler can this process be strong enough for manifolds?


Thanks

 

nobody?

 

hey man back purge means to go back over ur bead and heating it up
