MIG 200 tip problems

[countrygardener]

Can you give a better description of what happened? What type wire were you using? Is it copper coated? Is it birds nesting? Or are the drive rolls slipping? You can remove the liner to clean it out if you need to. Taking compressed air to the nozzle end can purge build up of the flakes of metal and build up. It takes a lot of welding to wear out a liner. I have had mine for 8 years and done considerable welding, with no cleaner/oiler system and it is still good.

However, given your situation, you may not be able to salvage the liner. Have you got any pictures?

Too much oil will ruin the feeding system. Which unit do you have EXACTLY? Is it the green Power I-MIG welder?

Is it birds nesting? - I'm not sure what that means but I suspect that it is doing that. It continues to try to feed the wire even after it gets stuck in the tube. This causes the wire to feed out past the feed rollers and coil up in the feed area and then to short out.

Take your liner out and examine it. If it was wet from water, then I don't know how it could have happened. I think you have something that has happened there with condensation. Typically feeding systems like this are trouble free as long as the liner is in good shape. Take your liner out and see what it looks like. The liner looks kind of like an old choke cable without the center wire. A lot of times flaking of the wire can plug up and cause problems in the liner. It might be salvagable. Generic liners can be found most places.
