Welded great, fed into the gun great, no issues. Great value.
Needed to do some repair work on our pontoon boat and due to conditions, positioning, etc... TIG was not really feasible (plus I'm just not very good at Aluminum TIG) so I bought a MIG spool gun and ordered this wire to try my hand at Aluminum MIG. I am very pleased with how this decision turned out as Aluminum MIG with the spool gun was a lot easier than I thought it would be. There is still a steep learning curve compared to regular steel MIG but it is still easier than TIG. This wire appears to be good quality and it was reasonably priced. I practiced on some aluminum plates for a couple hours before attempting to work on our boat and had absolutely no issue with this wire. It fed perfectly and welded great! The only point I had any issues was when I moved to a different part of the boat in which the material thickness required a different type of aluminum wire. Fortunately I ordered both the common types so I changed out the roll in my spool gun and had no issues. Even with buying the spool gun and two different rolls of wire, it still saved me a lot of money compared to taking my boat to a welding shop for the repairs!

looks like it will do what it is meant to.
I have not utilized it as of yet, due to not having argon at this time. It appears as it will do the job as desired. it is thin wire, much smaller than regular mig wire. Using it will be some what of an experiment when I get around to it.

A good wire
This wire results in a consistent bead when using spray mode for aluminum MIG welding.

Works great!
The media could not be loaded. I do a LOT of aluminum welding and have nothing negative to say about this wire. Great value, quality and works perfect with my spool gun.

Aluminum Welding Wire
Great stuff. I am using it to build the inner skeleton of my jon boat for the decks and floors using a mig welder. First time trying this and no real issues other than my lack of skill. By the way, I am better with the grinder 😁
