Does your
preheating take longer than specified in the cutting table?
Is the
cutting quality bad?
One reason
may be the incorrect setting of the flame.
A cutting
flame should have the correct mixture between heating oxygen and heating gas.
With propane,
it is approx. 1 part propane and 4 parts oxygen. For acetylene, it is about
1:1.
In the
attached video, you can see examples of a heating flame.
For the
correct adjustment often years of experience is necessary.
Alternatively,
you use APC, our fully automatic Oxy-Fuel Process Control System.
