These have a blue tip. However, in order to weld aluminum to steel, special techniques are required. Tig welding aluminum with a dc current:

The flux cleans oxides from the aluminum and it helps shield the molten puddle.

When you start welding aluminum with the stick welder, set the amperage and purpose to utilize about 0.025mm of the thickness of the work piece. An aluminum fertilizer spreader, or an aluminum bracket on a conveyor, or an aluminum pump housing , all might be examples of things that can be repaired if someone just has a dc tig welder. Form the weld puddle and add filler rod When you start welding aluminum with the stick welder, set the amperage and purpose to utilize about 0.025mm of the thickness of the work piece. To avoid this, you must isolate the other metal from the molten aluminum during the arc welding process. Initiate the arc and perform the cleaning action;
