Welding wire ?

I bought a Harbor Freight 151 (230V) mig. I tried the flux core wire that came with it and it hung up, spit and spattered. I was just about to take it back when I decided to try a spool of some flux core that was in another welder that had croked. That was the problem. The flux core wire that came with the machine is junk. With the good wire it welded perfect.
I've always been told not to buy anything less than 230V on the plug. Better welds and longer duty cycles. :headbang:
