Hey guys...Just wanted to add to the post if ya dont mind ?...Xringer..Its best you use Ox/Acetylene..Home Debot has a rig for $289.00 .Also you can use Silphos,FYI..You can probablly go to a local a/c wharehouse and buy single sticks,Instead of Packs.
I would pump down the system before Braizing the leak. If possible ?..Recover the refrigerant first..Braze leak..and vacuum down the system...Just a thought !!... I am in HVAC School learning the trade..By no means am I an expert..Funny thing..We are Braizing Now..Pretty cool stuff..And BTW ! Ya dont need the copper cherry red ! Oxy/Acetl. Gets hot pretty quick...When the flame is on the copper..The copper will turn kinda white...At this time ya wanna start your braze...
The Silphos when melted(Like water) will follow the heat..You can move it around your fix pretty easy....Good luck !!
