and check if you do (or don't) need glasses. I'm getting old I need my glasses of for close up work, make a world of difference when you can actually see what you are doing
That is also part of the problem. When I was younger I could focus my eyes on the work but now I need to move my head back and forth until the work is in focus.
It just takes a second for me to focus and get my bearings but a second is more than enough to burn a hole through thin metal.
I wish I could work on really thick work with a nice puddle, like in the video, and plenty of time to enjoy the progress.
