If you're welding, use equal pressure, pretty much. I don't find that written in stone but a good departure point.
If you have the cutting attachment, about 8-10PSI acetylene and 20 PSI oxy will cut 1/4" dead clean with a tip in fettle, no slag. For 1" steel the oxy will only need to be 40-50 PSI, acetylene stays 8-10.
Sorry, no metric conversions, have had the two pints.
What's the orifice on the #2?

You can get a cutting attachment for this????? its tiny

tip size, a 1.1mm drill bit is loose and 1.2mm wont fit so i think its 3/64ths
i only plan on using it for nickel bronze

from what i found on the web making bike frames seems a popular use for these

thanks for the info

"You can get a cutting attachment for this????? "

I'm not sure, but wouldn't be surprised. I have a tiny Harris aircraft torch that cuts.

This link may be useful. Be sure to read it because it contains
good safety points. Mind the maxium gas flow per size of cylinders. It
seems that bit of knowledge is not wide spread.
