Millermatic 211 issue

[millermetalworx]

IF you look at the pic I posted you can tell there is an issue. Im using the machine in 220, and cannot get it set correctly, its like the arc is erratic and not concentrated at the tip of the wire. When in the puddle the arc seems to be drifting. Its creating a lot of spatter and awful beads. Now when i use it on 110 everything is the way its suppose to be, I can dial it in perfectly and I get great results. I am relatively new to welding, and this is the first 220 welder i have owned, my first was the mm140 which i layed down some great beads with. My question is is it me or the machine, or another culprit? Also i wish i knew the volts and ipm instead of the numbers provided so i could be more precise.****ty welds.jpg

Several things appear to be required before we can help you in any meaningful way.

Post a better pic. A pic that is only an inch and a half wide and depicts a dozen or so welds is not sufficient. Resize your pic such that it is 800 pixels wide.

Open the door and look above the drive rolls and tell us if the ground clamp lead is connected to + or - and what kind of wire you are using and which shield gas if applicable.

Double check your 220 input, make sure it is 220 and not 208. Make sure you are wired L1-black, L2- white and green to ground.

Im using C25 gas and 70s6 .035" size wire. My metal was clean so thats not the issue, all though the picture doesnt look that way. The edges of the weld are so inconsistent and just plain bad. It doesnt feel, sound or obviously look right. I cant send welds out of my shop that someone has paid for that look like this. When im on 110 I have no issues at all. I build cattle gates and home gates and the welds are right in the customers face.

Unless he has 208 3 phase, thats unlikely to be the problem, s 200 and 208 doesn't come in single phase only. So the op problably has 230.

Unlikely to be wired any differnt on L 1 & 2. and ground as the 120 vac setting would be out to lunch.

Besides problem has little to do with the input.

Thanks cruizer but I thought the 211 came 120/230 only. Now I don not know about Canada but we have a lot of 208. Does 208 only occur in 3 phase supply to a shop?

My L1/L2 reference is if one lead is bad he will still get 110 but not 230.

I have read that the arc is harsh when on 220 but the way its welding cant be the way it was designed to perform. Should I try calling support? I will say i am running it on a 30 amp breaker that has a dryer plug socket, i made an extension cord to adapt to the 6-50 that's on the machine. I dont know if there's anything that could cause these issues from that set up but thought i would mention. An electrician is coming and wiring up a new panel in the shop this week, so maybe the issue will resolve itself..hahaha doubt it!

You won't find 208v in a residential service.

120/208v is 3 phase where you get 120v phase to neutral and 208v between phases.

.

We have alot of 200 and 208 as the 230 transformers are rather expensive in 3 phase, so no your not going to get 200 or 208 in single phase, least wise in north america.
