So I try to keep myself busy on my days off bettering myself in some way. Now that I purchased the new welder ive wanted to improve my aluminum welding. I made myself a purge block/heat sink and got to work. This is the first one I did, which I messed up in my opinion because I didnt use enough amps to melt the flange to the pipe. It required all 180 amps on my second attempt to get that done. The second one was coming out perfect when all of a sudden the alumnium wouldnt wet and turned black and caved in blew a massive whole in it. What the hell causes that to happen? I had argon flowing with a red tungsten. Either way this was a learning exercise so I dont really care. I also felt like I was chasing leaks....The pipe would hold fine until about 30psi and would start to leak on the left side of the weld...
