My wire feed welder seems to burn back to the tip very regularly....can I clean the sleve with anything? Would a drive wheel being too tight be a possible problem?

You can either turn amps down or turn wire speed up,make sure drive wheels are set for the size of wire you are using,one side is set for example .023 flip it over the otyher side will show .030.

The wire is slipping on the wheels and not feeding to the gun

check the tension on the spool - is it free to rotate ( but not so free it over-runs when you release the trigger)
check the tension on the drive wheels - are they turning and slipping on the wire?
Do you have the correct drive wheels for the wire size? if you're using .8 wire, you need to be using .8 drive wheels (or the .8 grooves if you have multiple grooves.
is there a kink in the liner? pull out the liner (remove the whole gun attachment, usually the liner will slide out from the end where it attaches to the welder). Blow out the liner with an airgun while you're at it as they fill up with crud.
When you reassemble the gun, slide a lenght of wire up the cord and check that you can push it all the way in freely.
Then when you rig the welder, leave the tensioner off the drive rollers, and push the wire into the gun by hand. you'll feel if there are any tight spots ( usually caused by kinks in the liner).
once you've rigged it, clamp the drive rollers shut and adjust the tension until they feed the wire smoothly. (leave the contact tip off the gun when you rig it as the tolerances are so fine that even the small flattening of the wire where you cut it will usually prevent it from feeding into the tip. Once it feeds properly, reshape the cut end of the wire and attach the tip (don't force it over the wire or you' ll just damage it)

I have had my Pro-MIG 140 for six years, never a problem. Pulled the trigger today, the wire got red hot and melted at the drive gears. Is this a problem with the liner? or something else? Im in the middle...

If you can feed the wire manually(by hand) the liner should be OK. I would replace the tip and verify all the welder connections at the drive wheels. Make sure all the connections are clean and tight.

Sometimes the drive motor collect a lot of metal dust from the environment and it requires a clean up. Take the tensor off and remove all wire, try to apply compressed air into it and then apply WD40 and run it. Make sure your tensor wheel it's not to tight and that you are using the right wheel size for the wire in use. Another problem rely on the gun liner if this one hasn't been change in 12 months, it is time to replace it, or, if it is not kinked at all, try to use clean air to blast out all metal particles from it. (take off you gas nozzle and gas mixer also known as contact tip holder).
Good luck.

Drive wheels slip and won't feed wire. tensioner tightened as tight as possible.

make sure your drive wheels and contact tip is the right ones for the size of wire you are using. if your tensioner is too tight it will crush your wire and it will not feed through your contact tip.

loosen off your tensioner and remove any wire that has gone through your drive wheels.

Millermatic 200 will not weld

1 - Check the ground connection to the work, including the actual cable to clamp connection.

2 - Make sure that the wire feed rollers are nice and clean. The wire needs to be clean too.

3 - Check that the polarity changing wire connections are nice and tight, clean, etc.

4 - change and or service the contact tip at the end of the gun.

as always, gently clean out the loose junk inside the case. A clean welder is a happy welder. :-)
