Is it possible to turn my 20 square foot welding table into an elctromagnet? I weld steel cut nails into artwork. The nails lay flat on the steel table, but the welding process sometimes "shifts" the nail out of position during the spot weld. This error causes the process to be shut down, and then phisically remove the welded nail. I thought that if the table were a large electromagnet, the steel nails would stay in place as I weld. Considering that the welding table is grounded to the welding machine, does this complicate the matter?
