@moparmusclecars new miller is junk now man. They are all the same welders from china I know because I bought a cheap china welder and it welds the exact same as that miller. Same shitty little Chinese inverter same ground prong same duty cycle. Just buy a yes welder atleast you get a decent sized ground and full size stinger connection. For 2 thousand less dollars you get a better welder lol. Shits backwards. If you want a serious machine buy a ESAB It failed because the drive rolls spun out every 5 seconds. They get a little moist and spin badly. On top of that everytime I would go to weld it was giving me a error code and the machine took around a hour to trouble shoot and get working when I needed those brackets welded on ASAP RN got the owner of the stadium with me I can’t have my welders be failing in front of those guys ever man. Pissed me off I got rid of the millers switched to ESAB and the new Lincon buzz boxes for field welders and never looked back

Just used this welder brand new yesterday and failed me. Don’t buy this new garbage dainty little ground prongs a waste of money. Can’t handle the weather either.

​@707SonomaComabut I do love the welder. Super easy setup and it welds SMOOTH!

​@707SonomaComa I have used it on 4 projects so far! I am just saying that's the only thing Ive touched, besides welding with it.

​@707SonomaComa It's been flawless! The 15' whip is awesome and feeds the small diameter wire effortlessly. The only thing Ive done since taking it out of the box was calibrate the wire speed. 👌

My millermatic 211 burnt out the motherboard after 2 2 pound spools of wire was ran through it. The cost to fix it it was more than the price paid new 2 years earlier. Miller said it was because it wasn't used enough??¿?? All they had to do was replace the motherboard but the wanted to include a $500+ diagnostic fee. I'll probably never buy milker again.

Same I bought mine in February, much rather have this version: I used it very little, so far good machine, I just like the features on this better.

I bought my Miller 211 9 years ago. With a 150 spool gun it has been an absolutely fantastic machine

Every time I have this binding problem, it happens while I'm welding, not on startup. Everything is going fine, welding along and BAM! the machine begins to labor, I hear it, just like you have applied a load to a PTO. There is no ryhme or reason for this, machine hot, cold, long bead run, short run. Sometimes I have just started using it, sometimes it's been running for a couple hours. Sometimes I use it all day no problem. I also like to run it on auto set and let the machine decide wire speed, but I have had it happen manually setting it. Guys, I'm not a rookie welder, lots of MIG, some TIG, even carbon arc (who remembers that? ) and I'm not being a uppity know it all. I appreciate every reply to this problem. When I conquer this problem, and I will, I will tell the world. Could it be that I have a Friday afternoon before a long weekend machine?

Have you checked the settings on the wire feeder. There are different diameters stamped on the feeder to adjust between sizes. I's also check my stick out. Maybe you're not leaving enough wire outside the gun while welding. The third thing I'd check is the wire speed. The only binding I've had with my 211 was at the tip with some slag splashback. MIG pliers cleaned it off easily each time. Good luck getting it going.

I agree it could be a liner issue, as far as kinking or coiling the stinger lead, this is a MIG problem I am aware of and I'm always careful to keep it as straight as possible, that was the very first thing I checked. I have not used it since I tried it at the Miller dealer.

The problem you're having is caused by by binding in the liner. I know, this is a brand new machine but if you lead is coiled up or a hard angle right out of the machine, this will cause excessive binding on liner, thus resisting wire feeding through the roller. THE CURE: when welding, make sure the cable/gun is as straight as posible, with no tight bends. this will ensure no tension is on wire when feeding through liner. this happens quite often on the smaller machines. I've got this machine and the 350P in the shop. The 350 has 4 grooved rollers, so the cable can be coiled up like a snake and still push through, but the smaller machines only have one, so weld with the machine as far away as possible so as to keep cable straight out of machine and i'll bet you have solved your problem TIP: switch you gas to 90/10 instead of 75/25
