Hi folks. I'm in need of some help. I would like to learn how to weld, but I don't know where to start. I'm comfortable with a Propane/Oxy blow torch in jewelry applications but know nothing about welding steel. The project is to construct a frame for a small trailer to be hooked to my (four year old) son's John Deere toy tractor. I was looking at steel at Home Depot. I can cut it, bend, etc. but need sopmebody to point me in the right direction as far as the welds go. Thanks in advance.
