Changing the liner in your MIG welder isn’t something that you’ll have to do very often, but it will stop you dead in your tracks if you don’t know how to do it the correct way.
Sometimes these kind of repairs can seem huge (especially if you have no idea where to start). Today I’m making sure that doesn’t happen to you!
Fortunately, changing your MIG welder’s liner is a cheap and quickly fixed problem.
Most liners have price tags from $18-$23 and can be changed in less than 10 minutes without any special tools.
WHEN DO I NEED TO CHANGE MY LINER?
One easy to diagnose this problem is if you know you have kinked your line in some way. Maybe you dropped something heavy on it. If you notice the wire running really slow or not at all after the drop, you need to change your liner.
Other times you may need to investigate a few other possibilities first.
If your wire starts running slow or has a start-stop-start-stop type action then the first thing you should check is your tip. It’s possible that you’ve collected too much slag on the tip, which can slow you down very quickly.
The next thing to check is the tension adjustment pushing the wire down onto the drive motor. A simple little turn of the knob may be all you need to get your wire feeding smoothly again. Especially if you recently changed to another size of welding wire.
If these aren’t the problem, you should replace the liner. Sometimes the liner is just old, filled with debris, and has met it’s end.

Don’t get caught with your pants down…
It’s always good to have an extra liner around just in case you need it.
You don’t want to be caught in the middle of a weekend project when your liner kinks up on you and half to wait until Monday to get up and running again.
