Long story, but I need to remove the trailer jack I just welded the shit out of on a friends trailer after putting it where he told me. I have a new Hypertherm 145 plasma with the gouging tips that can be used to blow out a weld. I'm just going to use cut-off wheels since I don't want to practice on this project, but it sure would be nice to know how the plasma gouge cutting works to do that?
I haven’t tried it on mine but a good friend of mine told me it works really well to remove welds and requires minimal touch up with a cutoff wheel or Roloc disc to completely remove the weld. if you’re concerned about the aesthetics of the finished product I’d build up a similar weld bead on a piece of scrap with the same thickness and figure out what technique works best.
