Pins 1 and 2 activate (turn on) the plasma cutter.
Pins 9 and 10 gives the “OK to Move” signal. These are Dry “N.O.” style contacts. It is a non
electronic switch that
closes
when the pilot arc transfers to cutting arc. Sometimes referred to
as “Arc OK”.
Pins 5 and 7 provide the raw, undivided arc voltage, which is used by some controllers to
adjust the height of the torch (THC). This is the actual cutting voltage. It runs through 2
-100K
Ω resistors to prevent arcing at the connector plug. Some controllers may use the raw
voltage, and is dependent upon the impedance of the input. CandCNC* controller and
Torchmate * do not use this voltage.
Pins 4 and 6 provide the divided arc voltage. This is selectable by adding a jumper on the
CNC circuit board to create either 1/16 th or 1/50th of the raw arc voltage. It may be used by
some controllers for torch height control (THC). Usually the 1/16 setting is preferred.
Pin 3 is what some controller manufactures refer to as “Ground” this is connected directly to
the work piece lead, which is actually a positive polarity. If the controller has a pin for ground
this is likely the pin to use.
NOTE: Do not connect anything directly to the output terminals or leads. Do not
connect anything from the controller to the chassis of the cutter, especially a ground
lead. Do not install any kind of converter or divider inside the machine.
