TECH TIP: How to Save Your Aluminum Wire

Proper storage for aluminum wire when not in use is KEY to making it last longer and for producing quality welds! 

Aluminum oxidizes rapidly, and this can cause issues with weld quality and overall strength of repair. When oxidation forms on the aluminum wire it will disrupt the arc and will be nearly impossible to maintain a proper arc.

ALUMINUM WIRE WILL GO BAD IF NOT STORED PROPERLY 

NO MATTER HOW LITTLE IT IS USED 

Although Aluminum is becoming more abundant during production, depending on the shop, Aluminum welding may not be a regular occurrence like steel is. Proper wire storage is very important when not in use, as the aluminum oxidizes rapidly and this can cause issues with weld quality and overall strength of repair.

This is something that is often an after thought or overlooked in the shop, and blame gets placed on welder instead of looking at the wire.

When Aluminum welding wire is not in use, we recommend:

1. Remove from the welder & torch.
2. Once removed store in either a zip lock freezer bag, or wrapping in cellophane (similar to how a new spool would come) is the best option.

When wire is stored properly, oxidation is less likely to form on the wire making for better weld quality, less chance of contamination, and longer lasting wire.
