Hi there I have a clarke 100en turbo which i converted to run on large gas bottles after advise from this site and it has been working great for over a year . Yesterday i had to change from .8 to .6 wire for some bodywork and the wire keeps jamming up. It always happens in the same place, between the motor driven roller and where the wire enters the liner, the wire seems to rise up and jam, this happens even if i am not welding but just feeding the wire through. I changed the wheel so the wire runs in the .6 slot and it was a new reel of wire, the only thing i did not change was the tip to a .6 one, i am still useing the .8 as i could not get hold of a .6 one. I have even moved the liner so there is the smallist possable gap between the liner and the wheel but it still jams, if i swap back to .8 everything is fine, any ideas please. Mouse.
