2.Turn off the height controller(M39).
3.Lift the cutting torch(M70).
The operation sequence of M08 in plasma cutting operation is as follows:
1
.
Turn off the arc voltage switch.
2
.
Turn off the height controller(M39).
3
.
Lift the cutting torch(M70).
M50: Piercing action
1
.
Lift the cutting torch(M72). There is no this step in plasma cutting operation.
2
.
Open the cutting oxygen valve(M12) or turn on plasma arc ignition and check for the signal of "Arc
Voltage Successful".
3
.
Lower the cutting torch(M73). There is no this step in plasma cutting operation.
4
.
Switch on height controller(M38).
M52: Fixed loop of ignition
Operation sequence: open acetylene(gas) valve(M10); turn on the high voltage ignition(M20); count the
ignition time delay and turn off the high voltage ignition(M21).
M70: Fixed loop of lifting torch
Used at the beginning of a program and at the end of cutting section, this command is to raise the cutting
torch for possibility to move quickly to next cutting position. The operation sequence is as follows: turn
on the torch lifting switch(M14); count the time delay of lifting torch(refer to 7.3 for flame parameter);
turn off the torch lifting switch(M15).
M71: Fixed loop of lowering torch
This command is used before piercing operation, opposite to M70 in funtion and little bit smaller in value.
Because of gravity, the lowering action is faster than lifting action. Operation sequence: turn on the torch
lowering switch(M16), count the time delay of lowering torch(refer to 7.3 for flame parameter) and turn
off the torch lowering switch(M17).
M72: Loop of lifting the piercing torch
At the end of preheating, this command is used to lift the cutting torch somewhat to prevent the torch
nozzle from blocked by splashing slag. The operation sequence is as follows: turn on the torch lifting
switch(M14); count the time delay of lifting the piercing torch(refer to 7.3 for flame parameter); turn off
the torch lifting switch(M15).
M73: Loop of lowering the piercing torch
At the end of preheating after M72 is executed and the cutting oxygen valve is opened, this command is
used to move the torch to the cutting position, opposite to M72 in function and little bit smaller in value.
Because of gravity, the lowering action is faster than lifting action. Operation sequence: turn on the torch
lowering switch(M16), count the time delay of lowering the piercing torch(refer to 7.3 for flame
parameter) and turn off the torch lowering switch(M17).
M75: Time delay of torch positioning
When positioning the plasma gun, lower the torch(M16). It will not stop until the torch hits the lower limit
switch (refer to input port 8 XXW)(M17). Turn on the torch lifting switch(M14). After count the time
delay of torch positioning(refer to 7.4 for plasma parameter), the lifting torch will stop(M15).
M80: Master switch
