initial use is because the arc column voltage may not the same for the
plasma power supply of different manufacturers even the cutting
operation is going on in the same environment.
Collect the test results
for parameter A (see cont
rol parameters in 7.1) . If the value of
parameter A has never been tested and the set value is smaller than
the actual voltage used in plasma cutting operation, then in aut
omatic
cutting mode the plasma cutting torch will move down quickly until it
knocks the workpiece; ot
herwise, it will move up all the way until the
arc breaks.
For an unfamilia r new plasma power supply to be used with the height
controller for the first time, arc vo ltage test must be made for t his
plasma power supply. As for standa rd plasma power supply, the
"cutting speed chart " in the instruction manual attached to the
plasma power supply should be referred to.
Simple test met
hod:
Manually adjust the distance between the cutting torch and work
piece to an appropriate value according to the power specifications. In
the manual mode of plasma, manually control t he height controller t o
sta rt arcing perfora tion. After perforation is complet ed, move the
cutting torch through the CNC system to perform actual cutting
operation; at this moment, the value indicated on the digital display of
the height controller is the actual arc voltage of the plasma power
supply in the current environment.
