I was wondering what type of welding tables everyone uses? If you made it or bought it? I made mine out of aluminum to be light so if I had to move it would be easy. I made it so beefy out of 1/4" 2" x 4" aluminum the beast weights about 80 pounds so it defeated the purpose. The top is removable I just lay it on top. I have different tops I use. The most common is a 1/8" sheet of 6061 aluminum with a copper sheet to absorb heat and protect to table. I tell you this table is the best ground you could hope for. I have never had arc marks on anything I have welded. If I want to hammer or cut something I put a 1/8 steel sheet on top of the aluminum sheet.
