4. Turn on the height controller (M38)
M70 Fixed ascending cycle of cutting torch:
It is used to lift the cutting torch when a cycle st arts and after one cutting cycle is complet ed,
the so that the cutt ing t orch can move to next cutting position quickly.
Operation sequence: turn on the ascending swit ch of the cutting torch (M14); start
the
ascending delay of cutting torch; turn off the ascending switch of cutting torch ( M15).
M71 Fixed descending cycle of cutting torch:
It is used before a perforation operat ion. Its role is contrary to M70, but the value is smaller
because descending is faster than ascending due to the action of gravity descend.
Operation sequence: turn on the descending switch of cutting torch (M16); start the
descending delay of cutting torch; turn off the descending switch of cutting torch (M17).
M72 Ascending cycle of cutting torch for perfo ration:
It is used at the end of preheating to lift the cutting torch a lit tle bit so as t o avoid any
sprayed steel slag from blocking the nuzzle of the cutting torch when the cutting oxygen
valve is opened.
Operation sequence: t urn on the ascending switch of cutting torch (M14); start the
ascending delay of cutting torch for perfo ration; t urn off the ascending switch of cutting
torch(M15).
M73 Descending cycle of cutt ing torch for perforation:
It is used at the end of preheating. After M72 is executed and the cutting oxygen
valve is
opened, the cutting torch is located in cutt ing position. It is the reverse action of M72, but
the value is smaller because descending is faster than ascending due to the action of gravit y.
Operation sequence: turn on the switch of cutting torch (M16); st art the descending
delay
of cutting torch for perforation; turn off the descending switch of cutting torch (M17).
M75 Positioning time delay of cutting torch:
To position the cutting torch in plasma mode, first let the cutting torch descend (M16) until
