Tip #1
If you have a project that requires you to weld aluminum,and you do not have a tig or mig welder,buy a pound of aluminum arc welding rod and use it to weld with your torch! this works very well,especially on thinner material.The aluminum arc welding rod is pretty expensive ($15.00-$25.00) per pound,but it does a good job and you don't have to invest in a tig or mig welder!!!
Tip #2
If you notice your torch is starting to pop,this means that it is starving for acetylene, especially if you are using a rosebud. This usually means that your acetylene tank is almost empty. Change the tank and try your torch again. If it is still popping, the the torch has probably been damaged!!!
Tip #3
The check valve that comes standard on most torch sets sold today are designed to stop gas from backing up into your tanks through the torch. They are not designed to prevent a backfire!!!! You must buy these separately. ($50.00--on up). They are well worth the price.
Tip #4
If you are looking for an in expensive way to braze stainless steel with good color match-up try using nickel/silver(Harris/Welco has a thin flowing and a bead forming series-welco 14 and welco 17).
