Hi, I have done my first brazing with a MAP torch and with 56 silver it works just fine but there are some drawbacks:
- The nozzle on the commonly available MAP torch is huge and it will heat up a large area, it’s hard to control
- 56 silver is VERY expensive, you are talking about lug frames so that’s ok as you will use a small quantity of it but just FYI, it will cost you a lot.
- You are starting steep with SS tubing and 3D printed lugs!!
What I mostly used my MAP torch was to braze cable stops and small parts as I was using tig mostly at the time (and not doing major jobs anyway)
I now have a more serious setup with an oxy concentrator:
All in I am up and running with $290 plug the propane tank that I already had and I have a setup that will last me forever and that will only require a propane refill to keep working.
