Yeah its not bad on 3/8 , surprised you only need 160A (maybe because your close to the edge?) I was at 200A and I thought my fingers were going to melt. But once the aluminum got warmed up, finishing up the welds on 3/8 is pretty easy.
I don't know how long we can run a bead at full 200A before the machine thermals (overheat)? Also is it bad to thermal the machine?
I also wonder if there is a benefit of using 1/8 tungsten from 3/32?
