[QUOTE="MrGiggles, post: 468602, member: 22613"] I have played with them. Harbor Freight has a cheaper version if you want something to mess around with. The melting temp of the rods and aluminum are not that far apart. Apply too much heat and you will end up with a far bigger hole than you started with. You have to be very proficient at oxy/acetylene welding to get it right. I patched a crack in the drain plug on one of my old boats. It's still holding up, but it's not exactly a high stress area. If you just needed to fix something small, it may be work. But you aren't going to be able to fabricate any big projects with the stuff. [/QUOTE]
