The CrossFire line of CNC plasma machines accept a wide variety of available plasma cutters on the market today. The only hard requirement is that the plasma cutter must not use a High Frequency start mechanism in order to initiate the plasma arc. These style of plasma cutters are strictly forbidden for use on the CrossFire line of CNC plasma machines because the High Frequency arc can cause permanent damage to the machine’s electronics components.
Fortunately, most modern plasma cutters today use what is called a Blow-Back start mechanism to create the Pilot Arc. We have compiled a list (link provided below) of plasma cutters that Langmuir Systems has deemed compatible with the CrossFire line of CNC plasma machines, all of which utilizes the Blow-Back starting method. This list is in no way comprehensive of all compatibility on the market so if you are unsure about your plasma cutter we encourage you to consult your manufacturer and inquire about the arc starting method for your specific model.
Additionally, we only recommend using plamsa cutters on 220v power. Plasma cutters running on 110v power require too little standoff distance to be used on a CNC machine.
Each CrossFire and CrossFire PRO machine comes standard with a universal torch mount which can accept both hand and machine style torches. They also include a kit that you can use to wire your plasma cutter for use with the CNC machine. The minimum torch lead recommendation for the CrossFire and CrossFire PRO machine is 16'.
Each CrossFire XR machine comes standard with a machine torch mount. Machine torches are required for the Crossfire XR machine. The minimum torch lead recommendation for the CrossFire XR machine is 25'.
