M Commands for Routine Cycles
M07 fixed perforation cycle
The sequence of flame cutting operat
ion
is as follows:
M07
1. If the gas (acet
ylene) valve is not opened yet, then open it and start ignit
ion;
2.
The
cutting
torch
descends
(the
descending
t
ime
delay
of
cutting
torch
starts,
see
M71);
3. Open the preheating
oxygen valve to
start
the preheating
delay.
If the preheating
time
is
not
enough,
press
the
key
【
