Hello all! I am the sort of person that can't just buy something without wondering how to make my own version. Lots of things that I was wanting to make require welding though - something that has appealed to me before. Plenty of research narrowed the choice down to either a SMAW or MIG welder; a quick look at the price of the welders on offer quickly made me go for an arc welder. Being short of money, I was wanting a welder under £70; I would prefer a MIG welder, but they are all out of my price range. New or second hand, I don't mind. What matters is that it works, and I can learn to weld with it. I was looking at a 45A-100A arc welder, but I don't know whether it would be up to much. The welder is shown here: http://www.amazon.co.uk/Silverline-...PXHE/ref=sr_1_1?ie=UTF8&qid=1337717132&sr=8-1 What thickness of metal could it weld, what types of metal, what electrodes would be good for this particular machine and would it blast holes in thinner pieces of metal?
