Replace the gun liner
I might have to, wonder how expensive it is.

$20 or so. What gun is on it? Factory Miller or a Bernard Q gun?
Factory Miller.

Look at arczone.com for the liner. They have good prices. I get all my stuff from them, easy since they are local to me.

liner
Millers have twico guns and liners. A good place is Profax.com the cheapest place I have found. I got 15' long guns for my Miller 35 sure made a lot of difference.

Read your manual and then check your polarity . I think it is set for intershield.

Thank you.I have found I go way to slow, suggested wire speed is 60 I was between 40 and 45 on those welds.
And the nozzle dip worked great, far less clogs. Now if I could just get the trigger to feed the wire consistently I would be happy, the slightest bend in the line and the wire doesn't feed.
you could check how much tension is being used as well. Maybe there isnt enough and its slipping when you bend the hose

True. Or the drive wheels could be on the wrong size.

I'll have to take a few pics for you guys. I'm not exactly sure what you guys are talking about.

The drive rolls are inside the welder and they pull the wire off of the spool and push it down the gun liner to the contact tip. There will be number stamped in the drive rolls that should match the size of wire you are using.

Pull off the panel like you were going to replace the spool of wire, you should see some sort of tensioning device where the wire is sent though the feed motor. Usually they are adjustable by turning a knob to tighten down on how hard its clamping the wire. There is also a channel where the wire rides and that is what readymix is talking about there are different siZe channels depending on the wire size.
Thank you for the explanation I think I understand. How tight should the tension be?

Usually in the manual it gives you general settings, i keep mine at like 3/4 of its max. Yiu can play with it and see what works best as well.

Here are the drive rolls in my Miller
Thanks guys, I don't have a manual on hand but I downloaded one. I'll have to read up one it, don't remember seeing the tension listed.
roller has wire size stamped in each face.
the face you can read should match the size on the spool your running.
the face you can read should match the size on the spool your running.
Looks like that roller is for 0.024 wire, as indicated on the visible side. IIRC, the other side should be 0.030.
The tension is the big black knob sticking up on the left of the drive assembly. There are horizontal bars that let you put it back easily after swapping spools. Yours appears to be run down as "tight" (or close) as it will go. Possibly trying to overcome a bad liner?
To swap spools, you back off on that handle till it pivots to the side, releasing the drive roll. You can then thread in the new wire, making sure to keep the end reasonably smooth so as not to damage the liner. You don't want a big cut bur from an old pair of side cutters on the end being fed in.
