Yes, you should change them. If you don't use your welder that often, your wire will start to rust (even in the high desert). Rusty wire is the death of liners. I have to replace mine almost yearly.
Also, those little clip on felt wiper deals will help keep the liner clean. Or paper clip and paper towel if your feeling like a cheap bastard.
