7. Position the weld nut to the weld nut clearance hole, firmly pulling on the copper welding wire allowing the secured flat washer to hold the weld
nut in position.
8. Holding the weld nut securely in place and using a MIG welder, weld in four places around the edge of the weld nut.
9. Metal finish as required.
10. Verify the nut is securely in place.
