I am new to welding and like most, my first project is going to be a cart. However, I have found some really good plans for small work tables and I wanted to find out if I build a work table and make it moveable can I still put my welder on it (Lincoln 135) and connect the work cable ground to the table? Am I running the risk of harming my welder or myself? The thought of the welder sitting on the same surface as the work I am doing bothers me, is this any real conern?
