Preventing Porosity in Aluminum Welding 

Wow. Love the subject matter expert sharing his immense understanding of ac welding and most importantly helping me develop my understanding of aluminum itself.

Great information! I had always wire brushed the oxide off then used acetone!

Thanks for the info. Great knowledge on the subject. In your professional opinion, could acetone work as a degreasing agent in place of ZeroTri? Thanks

i did not know this so thank you

Two things, you sound like your native country is England, so why say that word incorrectly?! And secondly you look like hack you up with a hatchet Harry from Lock Stock And Two Smoking Barrels. Top video though, good tips!
