currently installing 3 and 4 inch vacuum piping system rooting with 6013 and cover pass with 7018 taking about 30 minutes per joint , looking for a way to speed this up
orbital welding head? innershield gmaw?
orbital is probably cost prohibitive, and some joints are fit poorly
would mig welding these joints be reliable?
they run about 25 inches of vacuum
If this is indoors, then MIG or Dual-Shield would be much faster.
thanks Ernie , you should be paid for all the help you post here

Also, if the line has to be cleaned during the startup phase, the fluxless solid wire will save you time then.

Something else from a clueless newbie?
How the heck do you pull 25 inches of vacuum if there are only 15 inches of pressure to start with?
I gotta be missing something somewhere...

Different units, in. of Hg vs. psi.
