Re: How to fix this - after patch panel
A shrinking disc does add heat..lots of it..when it heats the metal, it expands it, and you cool it fast, it shrinks it to less than before you started ..
A trick I learned when I was doing some large seams was to keep a air nozzle in you off hand when welding...as soon as you make the tack ,you hit it with air to col it off as fast as possible
And all you want to do it small tacks..move around and let cool before making another..
