Aluminum Welding wire
ER4043
ER4043 is a versatile aluminum welding wire commonly used for general-purpose applications. This alloy contains silicon additives, which enhance the fluidity (wetting action) of the weld pool. These additives also contribute to a weld that is less prone to cracking, making it a reliable choice for various welding tasks.

This stuff is more than twice the price at my local welding supply. I am an amateur welder. This is my third or fourth spool of this stuff and it works great for me. I welded up an aluminum trimaran sailboat. I have over 50 hours of sailing time and my welds appear to be fine. About ten bucks delivered to my door is a killer deal.

This is great wire for your spool gun. Smooth nicely wound. And a really good price point too. I had never heard of this brand before but it works great.

For my first time welding aluminum I was surprised on how smooth it went down. Definitely buying again! 1/4 plate at 520 wfs and 22.2 v

I used this aluminum wire to weld the aluminum railing on my ski boat. Cranked the amperage down to the lowest setting on the mig welder. Has held now for about 10 outings, no weakness in the weld.

Great value, worked well repairing my aluminum trailer using my Millermatic 211 and spool gun.Welds were shiny, penetrated well, and were easy to clean the soot off afterwards.
