  1. hows come when i get a neutral flame the acetylene feather keeps wanted to come back and make it not neutral. It happens with both of my torches so I think it is my gauge but I'm not sure which. I have them set to 4 and 5 psi with them cracked open but the oxygen psi wants to build up.

  2. looks like a great tool i could use 🙂 do they sell these somewhere in the netherlands perhaps?
    (actually i run a shop myself, maybe if they are not being sold in the netherlands yet we can arrange something? dunno if it has any use dealing with shipping costs?)

  3. Hi. Apologises if I you mentioned this and I missed it but… do I need a special lens in my goggles to safely oxy weld aluminium?
    There seems to be some threads out there about the need for special goggles!

    If so..do you sell them?

    Great torch by the way!
