Welding with Clean Aluminum Wire and Base Metal
 Aluminum is a very common choice for wire and base metal when determining a MIG welding job. The better job you do of cleaning the wire and base metal before you start welding, the better the result will be. It can be the difference between a bad weld (top image) and a clean, consistent and attractive weld (bottom image).
Preparing Base Metal
Cleaning the base metal prior to welding is important for achieving clean, consistent welds. There are a few tips to keep in mind when preparing the base metal:
1. Use acetone or another organic solvent to remove oil and grease from the weld surface. Wipe it with clean water to remove any residue, and let it dry completely.
2. Use a stainless steel wire brush (one that is only used for aluminum work) to remove surface oxides. Only brush in one direction, and only do this after the metal has been cleaned with an organic solvent.
3. If the metal will sit for a period of time before welding, cover the metal so that no new contaminants may make contact.
4. Keep the aluminum dry and at room temperature.
5. Complete the job within a few days to avoid aluminum oxide reforming. If this is not possible, be sure that the metal is cleaned again before you continue.
Preparing Aluminum Wire
Clean aluminum wire is just as important as clean base metal. Several tips above can be considered when preparing the welding wire. Also consider these tips for optimum wire performance:
1. Store the aluminum wire spool in a clean place when not in use. Cover it to prevent coming in contact with dust and debris.
2. Keep the aluminum wire running as straight as possible through the torch assembly and utility lines. Friction can cause inner torch parts to wear and the wire could collect any of the resulting debris.
If you have any questions about welding with aluminum, please do not hesitate to contact the factory.
