Hey everybody Im new to the forum and I have only been in welding for 6 months and Im really starting to get interested in TIG... I go to a vocational school that has pumped out the last 4 state champions for South Carolina. What my main question is. How do I run a bead without undercut. I have asked my teacher and he says to feed more filler rod in which makes sense but is there another method I can add to this or no? How do you guys do when it comes to TIG? I can stick and MIG but TIG is by far the thing I want to do the most. Thanks in advance - Kyle
