Ok, managed to dig out the oven and shoved a reel in it overnight and tried it a short while ago. A couple of things to bear in mind. 1. This was the initial reel I tried which gave me absolutely horrendous results, see first pic. 2. I don't think I had the temp high enough (dial is broken) and it was only in approx half the time that Bohler say of their fact sheet. Ok so first pic is with my initial tests before I dried the wire. This one is non pulse pull. Still some surface defects but I think that is likely due to me not being used to pulling with a mig as all my Mig is Aluminium normally. This is non pulse push. Much better to my eyes but others may disagree. When I am saying push it is the same as I normally use with Alu so barely any angle at all. I will be doing more tests with pulse if I get a chance.
