I work on the garden a lot and my Coronar pruners constantly loosen during use. I got fed up with it and decided that I shall weld the nut to the bolt. The design is to use a nut with plastic inlaid within to stop the nut from unraveling from the bolt. It works quite well but when you combine that design to something that moves on an axis constantly hundreds and thousands of times, its not going to hold its own.

It was quite easy to do actually. My welder looks brand new since I’ve used it less than a few dozen times. I always store it in it’s original box. I was thinking of purchasing the gas conversion kit for it but decided I do not use it enough to warrant such a purchase. It’s a Lincoln brand; a brand trusted by NASCAR!
