Reduce the tension on the rollers so they slip if it burns back.

Also make sure the liner is almost touching the rollers. You can also grind a bit of a V in the end.

How much gas flow are you using, you might try a bit more. Mine will stick if the flow is too low.

I also use a 0.9 tip on 0.8mm wire. Helps when working up close.

I think you'll find the groove in the wire feed roller is slightly out of line, re-adjust it (with a small alan key) so the wire sits straight in the groove & you are not having to push it in manually. Back off the top tensioning arm aswell as Shenion suggests.
