I think only you know this answer... We don't know the amount of control you have over the shaking,,,I mean can you stop it in certain instances??? does it seem to be getting worse with age??? Welding is a good paying trade and I would think there would always be something you can make money at,,,even if it came to repetitive spot welding in a factory... I personally can't weld for shit without shaking,,,LOLz... Welding is a gift to be good at it and if you got the gift that is most of the battle...
