I got my welder on Wednesday and Argon tank Friday. I didn't have a chance to use it until this weekend. All I can say is I love it already. I used flux wire for steel and ran some beads. Had to play with the settings a bit like turning up the amps and turning down the wire speed. Eventually I got good beads and good penetration on butt welds. Swapped out the MIG gun and put in the spool gun. It was a lot of fun to use and was very happy when I got the hang of it. Cart is a little bad but the helmet is great. Wish the gun and clamp were a bit longer but I needed to make an adapter/extension cord anyway so that gives me the length I need.
