I am ready to do some patch welding on my 49 cab. I have no experience with this and hope not to botch it to badly. I wish some of you who have done this would chime in with some basics. Like wire size for the MIG, voltage settings, feed rate, etc. I've done a few test patches and am having troulble burning through the metal but I have .035 wire and think I should be using .023. Any comments would be appreciated.
