Okay, too many nice guys on this forum. That is not me.

You clearly do not have the knowledge, skills or equipment to do this job.

If you do buy the wire that dubby posted, you need Argon to run it. You state
you only have a flux core welder. Also you will need 145-185 amps to run
that wire. I am gonna guess you don't have a machine that can reliably
deliver that amperage. Copper alloys need a lot of heat to weld. I suggest
you get a oxy fuel rig to properly braze copper alloys. Propylene will work or
acetylene, if you are buying new I would go Propylene.

But with where you are at, do you really want to tackle brazing 1" refrigerant
lines. I strongly suggest you hire a professional with the right equipment and
training. Clearly this is a commercial application, are you willing to take on
the liability? Are you insured for this type of work?

Oh, I think a number of people would disagree with you,
but will enjoy the vote of confidence while it lasts!!!
