I found the Clarke FC wire to be rubbish also.
For outside on the van I tried E71-TGS FC wire (0.8mm) that's commonly available.
I've no idea of its in the same league as that Lincoln 211 (it's a hellavu lot cheaper so perhaps not) but it was a quantum leap forward over Clarke's stuff (which IMO they should stop supplying - especially with any new Gasless Clarke welder - cos all it seems good for is to make both the user and the welder seem a lot worse than they are).
