Have you ever wanted to weld some aluminum, just to discover the cost of a new MIG/TIG welder is a little too expensive? Don’t forget about the tank of shielding gas you are going to have to buy. As you may remember, from those late night infomercials, Alumaloy could be the answer. It is an easy way to weld aluminum, with no flux or shielding gas, and only requires an inexpensive tank of propane or MAPP gas, easily purchased at your local hardware store. Then again, there is always JB Weld for those down and dirty connections.
Alumaloy is available from several online vendors, some seem a bit sketchy, so you might want to just pick some up from ebay express – Link.
