How to Solder Aluminum. : Up until recently I didn't know how easy it is to solder aluminum with a propane torch. The torch I'm using has a broad flame so it's probably not as efficient in heating the specific area for welding. A torch with more of a pin point would do bet. Aluminum alloys provide more of a challenge to welders than steel alloys. Aluminum has a lower melting point and higher conductivity than steels, which can result in burnthroughs, particularly in thinner aluminum sheets. Aluminum feeder wire is softer than its steel counterpart and can tangle in the feeder. Choosing a. The first thing necessary for stick welding on aluminum is to have a machine capable of DC (direct current) polarity, and it must be capable of putting out at least 200 amps. If your welder meets these guidelines, you are in business. If you have a 120-volt, 140-amp machine, for instance, there is no way it will ever. How to Weld Aluminum.
