Small Welder handle .30??
I brought home a used but nice little Miller Sidekick 90Amp Mig. It has a new feed hose/Mig gun, but is set up for .30 wire. The previous owner had been using it for flux cored welding on fence posts on his ranch (terrible looking welds with that stuff!). I tried it out and it feeds very nice and I actually got a decent bead frrom the flux core, but I bought it to use gas and do MIG. The question...Can this little 90 amp machine use solid .30 with the 25% mix gas I've just picked up? I know.23 wire is what it was made for, but I would have to get a new liner and parts for that new hose. If I could just take out the existing .30 Flux core and put in solid that would be the least expensive. The hose/gun is a Profax180-3035-12, made for .30-.35 wire. I don't want to spend over a hundered dollars to go to a 180-23, which is made just for .23. I have been told if I just change nozzles and run .23 through the .30-.35 tube it will kink and jam it up. HELP!

..and what about gas with flux core?
...and I also meant to ask...What happens if I use the .30 flux core its been using, and turn on the 25% argon/CO2 mix I've added?? Doeas the flux core still smoke and splatter , or does the gas tame it down some? I've got a whole spool of that stuff.

Wire feeders of the world unite. if you change the tip to the proper size and your drive rolls will get tight enough you shouldn't have a problem running the 023 wire out of your machine. My 110 machine is a Lincoln sp135plus, the only thing I have to do is flip my drive roll and change contact tips. the liner is not too big as to cause it to jam with the smaller wire. My bigger field welder is a Lincoln LN-25 with a twecco #4 gun that I run 035 wire through yet changing the contact tip I can run 1/16 solid stainless wire through. Maybe if you tried to run 030 flux core through a 9/64 liner it would probalbly knot up on you. As for running gas and flux core the wire you want is 71m outersheild wire. this stuff is for heavy fabrication, like making a 1/2 in fillet weld in a single pass. plain ol flux core wire will smoke less with sheilding gas but thats about the only benifit draw backs are tremindous cost of flux core wire with the added cost of sheilding gas. save your flux core for feild repairs or really windy days

I don't know if your question was answered but with my welder .030 is .030 regardless of flux core or not. I didn't have to change anything (but the polarity) to run solid wire with 75/25 gas mix. It makes a big difference in my ability to weld. I suck with flux core.

If I use .23 in the.30 gun, do I need to change just the hot tip, or also the nozzle it screws into.(That nozzle is marked .30 also on my Profax gun).

My welder only has one nozzle regardless of which tip I use. I have not heard of having to change nozzles to match tip size but then again I'm just a DIYer so I have limited exposer to welding in general.

I am a welder by trade and with the shops big miller and my little hobart 175 (a 220 volt) all we ever have to do is change tips and maybe drive rollers and we run everything from .023 to .045 in solid and dual shield. with solid i run 75/25 gas and with the dual shield i run strait co2 the dual shield has a flux center but still requires the gas. With the larger welder though it puts down alot nicer bead than the hard wire and is a stronger alloy. Hard wire and flux core are about equivelant to 6013 (60,000 psi tensile strength) arc rod while dual shield is equivelant to 7018 (70,000 psi tensile) the smallest size for the dual shield is .030

don't listen to you need a new liner if you go from .035 to .023". changhe the tip only. you may need to lighten the drive roller tension when you changeover to the thinner wire.
I just noticed that edit bikeitswift. that would be one bad &%! 90amp welder.

my 2c's , dont forget to switch your ground if going fron hard wire to flux core , it actuslly does make a difference in the strength of the weld and if im not concerned about a pretty weld the flux core and the dual shield are both stronger than the hard wire and cheaper to run, good luck , bob
