HP103 Plasma Torch Height Controller

directly above the torch.Find a mounting location away from the
torch lifter unit.
2. Attach the wires from the CNC,the plasma,the lifter motor and
lifter limit switches to a connector and then to the control box at the
receptacle. To reduce noise emission, 20 AWG (0.5 mm2) shielded
cable is recommended. Filters consisting of a resistor and capacitor
can be connected only directly to the motor.
3. Connect a 12 AWG (2.5 mm2) ground wire to the ground
screw located on the control box and then, to the machine ground
rail of your cutting system.
3.3 Divided voltage board
Controlling the arc voltage must inspect the changing of plasma
arc voltage. The plasma arc voltage equals the voltage that is
between the pole and ground. The anticathode which put out the
plasma power is connected to the ground. The Cathode connects
to the pole which is in the cutting gun. So the voltage in the
electrode is negative. When process the cutting, the arc voltage
absolute value is usually higher than 100V. If so, the voltage must
be divided in order to process the control in the controlling circuit.
ATTN: the voltage that put into the height controller is negative.
If the polarity is connected in reverse, the Height Auto-adjusted is
not available.
