Hello,
Beginner here. I have a heat exchanger that has a copper manifold. What I'm planning to do is solder the 1" inlet to a copper to CPV adaptor. Since the heat exchanger is expensive, I decided to buy 1/2 pipes with fittings to practice.
I did prep the pipes well and put a generous amount of flux, but the moment I apply heat the flux evaporates instantly and the solder won't stick. I decrease the heat but the flux just evaporates.
For the torch, I could not find MAPP or Putane so I went with Butane.
What am I doing wrong?
