My mistake 3/32" tungsten, late night doing a design. Im practicing on some 22 gauge but ive had it do it to me on 1/8 as well. Yes Im inside no fans. 100% 10-15cfm, tried like I said 1/8, and 0.030 mig wire ER4043, been making sure to clean it real well. Could the material im welding on affect it its a old 1/4 table, what about insufficent ground? you guys rock btw
