The one i found with my Clarke is if you get burn back on the tip it causes the wire to bunch just after the feed roller. Make sure the wire speed is fast enough to prevent burn back.

When you change to 0.6 make sure liner in good condition as it doesn't feed as easily as 0.8, I ended up replacing my liner as it was causing judder on start up even with new rollers and tip. You need a good consistent feed when welding thin material.

just out of curiosity, what would cause a liner to fail?

 

 

Damage to the wire itself, when this travels up the sleeve it can cause pickup inside the liner which will then drag the wire down in speed no matter what speed you have it set to.

It's easy to prevent the wire bunching after the roller when it sticks to the tip, just adjust the brass part so there is almost no free space between end of roller and tube then only have enough tension on the feed so if it sticks the rollers slip on the wire. Saves a load of hassle when welding as then you just free the wire on the tip and no mess to sort in the welder. You should be able to see what I mean on this pic of my wire feed

Certainly not got that adjustment ability on my Clarke. I have next to no gap anyway but it will still bunch up. Just a poor design but with care and the wire speed adjusted it does not happen that often.

I bought a new torch which included the liner etc of fleabay for not a lot of monies. Teflon lined if i remember rightly.

Some info here on liner replacement with a step by step guide.
It easy to test your liner just lift top roller and see how easy it is to pull the wire from torch end, it should be smooth and easy to pull.

I always go for a steel liner as I will only ever weld mild steel with this welder but Teflon if welding alloy or stainless
