Have you changed the tip? If you tip gets worn out (its hole gets larger where the wire comes out) it can't transfer the amperage to the wire.
Brian , I have not had a problem ether welding metal I just sandblasted. I have a cheapy Century 100 and I use the JW Harris Twenty guage wire with gas.
Ripped What kind of wire are you using ? I read throught this thread and don't see this mentioned . Hope you get it sorted out .
