does anyone know of a way to make an add on tip that will spot weld for my Lincoln 135 mig welder? I tried to locate this item from lincoln, but had no luck. I made a copper tube with vees cut in each side and it worked half way decent, but would value others input. I plan to use it to weld in my replacement floorboards. Thanks in advance.
