Thermadyne 1440-0241 Firepower ER5356 Metal Inert Gas Wire Aluminum 1-Pound Spool

I ordered 2 spools on Amazon to have as backups, I use a lot of aluminum wire. I'm a professional welder with over 30 yrs experience. I use a millermatic 252 with spoolgun , I was running 4043 wire when I ran out on a weekend and decided to try this 5356, same wire speed, same heat and this wire ran like it was on spray mode, clogged 4 or 5 tips after trying to get the right setting, decided to not use it, going through too many tips. waited for welding supply to open and bought some more 4043 same settings as before and it ran great. I have had good results with 5356 before with other brands like Radnor but not this wire. maybe it will weld if I kept messing with the settings, but like I said I was going through too many tips trying to figure out where it would weld. Not satisfied at all with this wire. Maybe someone will have better luck than I did?
