Brazing test using aluminum hard wax of Shinfuji Burner
Since I am a beginner, I started practicing from the place where the flux was melted.
It ’s the process until the brazing is finally successful.
* The scenes roasted with the burner are almost uncut, so if you are in a hurry, please use the chapters (when watching a computer, you can move to the previous or next chapter with [Ctrl + arrow keys]).
