I'm gonna put this here because technically it is an AC repair.
So I picked up a free mini fridge that had a big hole in the evap coil. I got a new evaporator, now I need to braze it into the system. This is a procedure that I only have a passing familiarity with, but from what I understand it is similar to soldering, just with fewer irons and more heat.
I am practicing with the damaged evaporator and some copper brake tubing I had around that happens to be the right size. I am having issues getting it to take. All the videos I have watched and instructional articles I have read say my heat should lead my filler rod, but I can't get the rod to melt unless I keep it in the heat, which so far has only resulted in lots of sparks and boogers that didn't seal, or even hold. I can break them off with some pliers and pull my practice pieces apart. This is leading me to believe that I have a less than optimal filler metal for my application.
So what I am trying to do is braze a 1/4 ID copper line into a 5/16 ID copper line. What is the best material and rod size to do this with?
