I keep going back and forth if i should pay someone to do it or try myself, both seem to be a pain in the ass lol. Ive been watching a few mig videos how to weld and keep a square frame true and just as i get a little confident i then worry about frame twisting ect, ive asked on a welding forum if it will be a easy enough challenge for a beginner but they say even a expert struggles to prevent twisting. How hard is it guys?
