PGN Aluminum MIG Welding Wire - ER4043 .030 Inch - 1 Pound Spool - Aluminum MIG Wire with Silicon for Puddle Fluidity and Enhanced Weld Durability - For All Position Gas Welding

I bought this to weld up some holes from self tapping screw holes that have become elongated and couldn't get it to stick or even lay a bead on the aluminum pieces I was working on. I even used some flux to see if that would help also different heat settings nothing. It also kept getting stuck in my mig welder line feed. Contacted Company and as of yet still no response.
