Welded up the Passenger side extension to the rear of my super duty's frame. This was a 1/2" thk L Beam with a 1/2" top plate welded over to complete the "C". Full penetration on the root pass all around. Used a chamfered aluminum backer bar to allow for a small fillet to fuse thru and help shield the root. ran at 28V and 600ipm on .035 wire which didnt seem up to the task of handling the amperage. You can see in the weave cap that I was having a helluva time keeping the wire stable. All of these welds will be ground smooth and flush for painting once I finish the driver side this afternoon.
