I am new to the form and I need some help. I have a Millermatic 211. I am using flux core wire and the flux coverage is very spotty and the weld does not look good. I start with the settings on the panel and have adjusted the wire speed and voltage to no avail. What is interesting is the first weld after a cold start with the welder has pretty good coverage. After that, not so good.

POLARITY Change for Gasless Fluxcore...Originally posted by lonestar1 View Post
Hope you have changed it..?? from DCEP for gas shielded to DCEN for gasless fluxcore
Wrong polarity will give poor weld bead characteristics

Polarity as said above. You did not say what you are welding? Mild steel I assume? How thick? Is metal prepped & clean? If sheet metal then you may be kind of burning through & sucking contaminants in from the back side. Are you trying to fill a large gap? Same issue. Are you pulsing the trigger (on & off)? This will leave you without enough flux coverage. Wire stick out should be more than welding with gas.MM250

Thanks for the suggestions and I checked them all. No luck in solving the problem. I am convinced it is a wire feed problem, but the Miller repair said no. I sold the welder and am going another route.

Could very well be a feed problem. I just found an issue with my Millermatic 211 where the wire does not line up with the grooves in the drive roller. Miller is convinced the motor/shaft is the issue, but I am hoping it is just a mis-machined drive roller. All grooves are off-set about 0.010-0.012", enough that when I swing down the roller arm and slip the tensioner up, the wire ends up still sitting on the flat portion of the roller, and doesn't scoot into the grooves. we'll see.HTP Invertig221 D.V.

I have noticed from web videos that some machine drive wheels have a serrated pattern for flux wire, also the tension it typically less for flux wire. How is your liner condition? Just some thoughts.Comment

This 1hour Fluxcore Video goes into a bit more depth....
worth the time spent if you are just getting started....

not the first time that i had heard that the 211 has feed issues, causing lousy beads, just repeating what i have heardComment
