Been searching the web to this question, but couldn't find out.
Heating copper by acetylene torch makes the copper softer, (then let it air cool) to work with when making a swage joint or hard to work with?
And, what would be the best tool for making swage joints? Hope not the swage punches.


Check out the Rigid website - Here
I've used this tube expander tool, it works well.


Thanks for the move and tool information.
I found out my answer. When heating cooper up, red hot, then air cool makes softer. But for my in class it seems it didn't when I was swaging.
Another point is that most technician just use couplings, instead of just swaging the cooper.
