Blue Demon ER4043 X .030 X 16LB MIG/GMAW General Purpose Aluminum Welding Wire, All Position with Silicon Additives, Formulated to Provide Porosity-Free, X-Ray Quality Welds

Newer Miller 211 with Spool Mate 150. Works good for general purpose AL welding. Doesn't like the lower settings on my setup, anything under 5 and its pigeon poo globs. 9 gives a nice good spray arc, seems to be a good middle ground for me at 6-8, 50-70 (Miller settings). 4043 generally is softer wire, had a couple bird nests with wire burn backs, mostly my fault. Did some non-scientific destructive testing on welded 6061 (not re-heat treated), welds held good, breaks occurred at weld edge, results were as expected. Tested a row of craters created on purpose, cracked right thru them all, fill those craters !! Spool gun lets me know I'm getting down to the end... more strain in the feeding, I suspect its the tighter radius having to straighten out. Overall, I think this wire was worth it for me. Seemed to perform well and as expected. I would consider buying again.

No problems but there will be about 20' of wasted wire on each spool. I have used 6 of these and every time, without fail, when the spool gun starts having issues of the wire jumping off the wheel/roller....I will open it to find a couple layers of winds left on the roll. Giving up and replacing the roll with another ...and no more issues. It might be how the coils are wound or just the variance of it moving off the core quicker but either way it is something to be aware of- don't give up on your gun just replace the wire with a fresh roll! . For reference eI am using a Lincoln Electric Magnum SG100 spool gun I have not had this issue with other brands.

I have a small welder but even being on max going slow on 1/8th inch material, the aluminum wire balled up and did not melt anything but itself. Not that I thougt that it would work without argon but now I know it does nothing with my welder. Bottom line is ...i personally think it’s good quality wire but its not for me.

I was hesitent to purchase a brand I was unfamiliar with, but I found the video that they posted very informative, and it made me feel they care about there wire. So I pulled the trigger on it and I was very satisfied. I think they compete very well against the likes of Hobart, and Lincoln in wire quality, and they beat them on the price by several dollars. I will be purchasing again.

My husband liked...said worked.

It's a good quality product, but you need to have a powerful welder to use. My 110amp did not do the trick at all, the wire just melted on top of the pipe. Once I moved up to a much more powerful welder I had much better success

Works just as well as Major brands and a lot less expensive

good stuff

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.

très bon produit, fait de belles soudures luisante et se soude bien.

Awesome product

bon
