Forge is ‘melting my face off hot’ I used timgunn’s 90 jet for the Amal injector and it OLs my probe rated at 1300degC (2372degF), ran it at 10-15 psi and it melted the ceramic fibre rated at 1430degC (2606degF). Welded a couple of stainless san mai billets today, chuffed! One pic is of the billet with a drop of ceramic on it and a blob of molten ceramic next to it, after shut-off.
