I am running low on gas and bought som flux core wire for my Mig welder. I had .23 wire in there, so i changed all the stuff inside to make it ready for the flux core. Now it is slipping. is there a fix?

The drive wheel inside the welder cabinet has two grooves in it. IT is currently on the small groove for the 0.023 wire so the larger wire won't seat in it. You need to take the drive wheel off using the proper Allen wrench and reverse it so the larger groove will be in line with the wire.

I think it will depend on the type of welder. I have a tension adjuster in mine and can put a little more pressure if I need to. Make sure you have a clean tip and that the lead is as straight as possible.

I was speaking for my Lincoln which has both a tensioner and the grooved wheel.

yes adjust the tensioner /change the drive but on some welders you must change the tip so the larger diameter wire will pass through also helpful is to blow out the inner occasionally with the air hose
welders that sit around make rust on the wire reel it falls of on its way through the inner liner and helps to create jams

Get more gas. That flux core spatters all over the place. Too much clean up time.

I turned the wheel over and everything, and yes it does spatter everywhere. Seems like barely any of it was sticking. It does have a tensioner, i'll poke around and see if i can make it tighter.

you might have to get a new wheel. i've seen some welders that have a knurled wheel for flux-cored wire.

the tensioner wheel just needed to be tightened. I didn't see that it could be tightened, but upon closer inspection it was a little knob. Thanks for the help everyone.

The knurled rollers are designed for the softer flux core wires as far as I know. I like to set the drive roller tension so that I can have the wire run against my glove at about a 2" radius as soon as it exits the tip (and curls around) without slipping or causing a birds nest at the feed roller. Check to make sure the drag set on your spool brake is not to excessive. I should stop the wire spool so that there isn't much sag in the wire before the inlet tube. As mentioned you can clean out the liner with solvents and compressed air. If you replaced your liner, it could cause binding if the liner was not trimmed to the correct length. Use a torch tip cleaner to file the inside bore of the liner once it has been cut to size. Your feeder tubes will also develop grooves over time, turn them a 1/4 or 1/8 turn periodically. As earlier mentioned, a coiled whip can cause extra drag between the wire and liner, keep a long flowing arc or keep it as straight as possible. If your wire gets stuck to the tip, simply pull the whip straight and give it a snapping twist or little shake. It usually frees up with a little pop. Hope this helps.
Just out of curiousity; why did you change to flux core?? I can't stand the stuff.

the only time ive used gasless wire is on sight there is nothing wrong with it

replace your liner in my experience that is normaly 90% of the problem and the tip

do not put too much tension on the wheel if there is a kink in the liner or the wire fuses to the tip it will kink up the wire and turn into a birds nest
