I started using my Lincoln 125 flux core welder tonight. I decided to try it on some scrap original sheet metal I had laying around. I used 3 washers so I could try tacking and rosette welding. I could really use some tips because I think my weld jobs leave a lot to be desired. I did get what I thought were a couple of nice looking tack welds after being in the garage for an hour. Suggestions? When I charge some camera batteries I'll post some pics.
