3, torch down (M73), plasma has no this movement
4, Turn on the torch height controller (M38)
M52 ignition fixed cycle
Turn on gas (acetylene) valve (M10), turn on high voltage ignition (M20), delay ignition, turn off high voltage
ignition (M21)
M70 torch up fixed cycle
It’s used for the start and the end of a program, torch up, to make torch move to another position. Turn on
torch up switch (M14), delay torch up (7.3 flame parameter), turn off torch up switch (M15)
M71 torch down fixed cycle
It’s used before piercing, has adverse function of M70, the value is small, because of gravity, down is faster
than up. Turn on torch down switch (M16), delay torch down (7.3 flame parameter), turn off torch switch
(M17)
M72 pierce torch up cycle
It’s used after preheat, torch up, avoid flying slag blocking the nozzle when turning on cut oxygen. Turn on
torch up switch (M14), delay pierce torch up (7.3 flame parameter), turn off torch up switch (M15)
M73 pierce torch down cycle
It’s used after preheat, finish M72, after turning on cut oxygen, torch is in cutting position, the adverse
movement of M72, and value is small, because of gravity, down is faster than up. Turn on torch down switch
(M16), delay pierce torch down (7.3 flame parameter), turn off torch down switch (M17)
M75 torch location delay
Plasma torch location, firstly torch down (M16), touch low limit (input port 8 XXW), torch down stop (M17),
then torch up turn on (M14), after torch location delay (7.4 plasma parameter), torch up stop (M15)
M62 draw line function starts
After M62, torch offsets a unit of a draw line offset (parameter-system) till M63. There is no kerf compensation
when drawing line.
M63 draw line function ends
After running M63, draw line function is over, torch return an offset from current position
M80 close
Execute M80, all output ports are closed
