Figure 21: Piercing
NOTE
If the metal is not pierced all the way through it could mean that there is not enough
oxygen flow. Other possibilities could be: the wrong tip size, hose size, or cutting oxygen
pressure being used.
Figure 22: Cutting by Piercing
Upon Completion of all Cutting Operations
Shut off the oxygen preheat valve. Then, close the torch fuel valve. Be careful not to shut 1.
off the fuel valve first, this may create a “pop” type sound. When the “pop” happens it
throws carbon soot back into the torch and may in time partially clog gas passages and the
flashback arrestors.
Close both cylinder control valves on the gas source supply.2.
