By Derek Odom. 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 weld on aluminum.
7. When welding out of position (vertical, horizontal, or overhead welding), keep the weld pool small for best weld bead control, and use the smallest wire diameter size you can. 8. Be sure to match your contact tube, gun liner, and drive rolls to the wire size you are using.9.. Clean the aluminum before welding, to remove the oxide layer. Use a stainless steel wire brush used only for cleaning aluminum. 5. Fill the crater at the end of the weld to avoid a crack. One way to do this is to dwell in the weld pool for a second at the end of the weld.
