ahhh cmon Cactus some of those ole big 30's and 40's were pretty tough machines and welded fine. I have burned a lot of rod with a 30.
Robert I got the same problem with my big dinosaur Hobart (93 3020g). Cannot even find pictures...anywhere. I gave up and just got the sharpie out and marked it where I needed it for this or that rod and went back to work.
They have a three piece but it is not the same. I am going to take it to a shop down the road that does race cars, and vehicle wraps while it can still be read an see what they can do. Maybe they can put "Vantage" on it instead of Big 40D
