Hi,    I have inherited an Oxy welding kit from my father inlaw. I am a newby to welding and wanted to know if it would be any good for welding galvanised water pipe. What would be the limitiations of this type of welding?
Reply:No, you don't want to be welding galvanized stuff as a newbie because the fumes are dangerous.  A search will provide further info.  Also, you don't want to start out doing anything that holds pressure or that could hurt someone if your welds failed.  The classic example is a newbie making a trailer as his first project.You can do a search on oxy-acetylene welding and learn all you want to know here.  You might consider also picking up some welding books from your library to get some general overviews.
Reply:The limits on Oxy Acetylene welding are the tips that can be used in your torch, and the withdrawl rate for acetylene based on the tip size. You don't want to exceed the 1/7th rule with acetylene. Small torches and small cylinders can easily exceed that rate even with small tips. If you have a heavy duty torch that can take large tips and manifold acetylene cylinders to prevent issues with the withdrawl rate, it's possible to weld very thick steel with OA. It's not terribly practical, since used stick machines are cheap, but it's been done in the past in industrial settings.Picts and descriptions on the size of your cylinders would help as would any info you have on your torch. The average  name brand starter torch set can usually easily weld up to 3/16"-1/4" steel with the right sized cylinders and tip..No government ever voluntarily reduces itself in size. Government programs, once launched, never disappear. Actually, a government bureau is the nearest thing to eternal life we'll ever see on this earth! Ronald Reagan
