Just inherited an Oxy/Acetylene torch that has both 1 and 0 tips. Any general rules of thumb as far as what pressures to set the two regulators to in cutting some 1/8" steel? This is just for fun.
Many thanks,
Gary
When I was taught it was 5 psi Acetylene and 20 psi Oxy.....should get you going.
In case you don't know, only open the Acetylene valve about 1/4 to 1/2 turn...faster to turn off in case of.....
and open the Oxy valve all the way till it stops, it has a seal at the 'top' also.
I was also taught to crack the valves slooowwwly.....so as to not shock the regulators I believe.

On my Airco torch a No. 0 tip is way too big for 1/8" steel. It will work, but it will leave fused slag on the cut and it will be a pain to grind clean.
5 psi and 20 psi will get you started. Jeff's advice for the valves is for the cylinders, NOT the regulators.I suggest that you do this for any gear that hasn't been in use recently: attach just the hoses to the regulators and briefly use the gasses to blow out the hoses. This is a part people often ignore and then they wonder why their torch valves get clogged up.
