1/16" MIG wire in a Millermatic 251

Have you got some 3/64 wire the kind you use the 0.047 hole inside contactor tips for? Do you foresee needing anything bigger than that?

The thing about mig and aluminum is removing the weld if you don't like it. It isn't like steel where you just pick up the 15 amp grinder. That alloy you mention kind of clogs aluma burrs (carbide things which go in die grinders or air tools spinning somewhere around 20,000rpm.)

Have you wandered around the internet and found the miller discussion group on the miller site moderated by miller employees?

I kind of wonder the same kind of question about my welder and 1/16 dual shield. from the manufacturers data I would need 400 amps or so it varies, the more you turn up the voltage the more you turn up the wire speed and hence the amps go up.

Is a millermatic 251 rated the old way 251 at 60% duty cycle or the new way
