Thanks for the great advice. Sadly I sold my father's old 1960s "big box on wheels" type of welder around 15 years ago, thinking I would never need a welder again. Famous last words. A few years later I regretted selling it. I will try some of the little 100 amp welders on the market and see if I can find a winner. I am sure a brand name one might be more reliable than the huge number of no brand Chinese ones? Then again they probably all come from the same factories.

Talking about Ozito, I have had a little Ozito hedge trimmer for donkey's years and have really put it through some long and tough treatment. It still keeps going. I expect one day it will fly to bits on me, but I don't really care if it does. I can only say that little machine has paid for itself many times over.
