I've had several soldering irons over my life time. I was never very good at it. Always something I didn't have or had the wrong kind. I could never weld, although I was several times given the task of hiring welders, especially aluminum welders for a certain plant. I arranged for a company who did lots of aluminum welderinng to test welders for me. I was most always a paper shuffle. I've always been that way in my personal live. I couldn't do anything so had to hire it done.
