I picked up a smith MW5 torch handle used, in nice shape, but for more than I wanted to spend. My question is to what tips will be most useful? if you had a part number that would most appreciated. My local welding supply store retails the tips for about 3 times internet supply houses price (around $30).
i also have a chance to buy an older airco torch but I'm reluctant to purchase older stuff, as it seems hard to find parts for.
Maybe this will help: http://bikesmithdesign.com/Welding/Tips.html
Most builders use anything from the equivalent of Victor #0 to a Victor #2. I think the #2 is the most versatile for framebuilding, but a #0 is good for learning as you won't be able to get into trouble as quickly.
