See what plasma cutters are compatible with CROSSFIRE™ CNC Machines.
The CrossFire™ CNC plasma tables were designed to accept a wide variety of available plasma cutters. 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™ machine 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 of plasma cutters that Langmuir Systems has deemed compatible with CrossFire™ machines that utilize the Blow-Back starting method. This list is in no way comprehensive of all compatible cutters 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.
While some plasma cutters can use 110V power, Langmuir Systems only recommends the use of 220V Plasma Cutters for the CrossFire™ CNC plasma tables. 110V Plasma Cutters require standoff distances too short for CNC Cutting.
We choose to partner with RAZORWELD to pair a powerful line of plasma cutters with the CrossFire™ machine at an incredible price. Take advantage of discounted pricing by bundling your CrossFire™ machine with a RAZORWELD plasma cutter.
For customers looking for a professional-grade system, Langmuir Systems partnered with Hypertherm to bring the Powermax line of the Plasma Cutters to CrossFire, CrossFire PRO, and CrossFire XR. The Powermax 45 XP, Powermax 65 SYNC, and Powermax 85 SYNC are perfect pairs for any Langmuir Systems Plasma table. Note: Extra care should be paid to insulate the water table of CrossFire and CrossFire PRO for cutters rated over 45A.
For more information, please view the product brochures for the Hypertherm Powermax 45XP and Hypertherm Powermax 65 SYNC and 85 SYNC
Splicing into the torch trigger wires may or may not violate your plasma cutter’s warranty. It is your responsibility to check with your plasma cutter manufacturer regarding the terms of the warranty and whether or not executing the splicing procedure violates those terms. Langmuir Systems will not be held responsible for warranty violations.
Completing the procedure requires opening up the cabinet of your plasma cutter power supply which will expose you to high voltage and high amperage electrical components. It is your responsibility to make sure that all work is done safely and with the power disconnected. If you have any doubts regarding your ability to safely perform this work, we strongly urge you to solicit the services of a professional electrician. Langmuir Systems will not be held responsible for any injury or death resulting from the incorrect or unsafe execution of this procedure.
After the wire splices are made, it is critical to never leave the torch firing cable connected to the CrossFire electronic enclosure when the torch is not installed in the torch mount and ready to cut. If the torch is required for hand cutting duty, it is imperative to first disconnect the torch firing cable before removing the torch. Failure to do so creates the opportunity for the CrossFire electronic system to turn the torch on when the torch is physically in an unsafe location; such as in the presence of volatile or explosive substances. Failure to disconnect the torch firing cable from the electronic enclosure when the torch is not installed can cause serious injury or death. Langmuir Systems will not be held responsible for any injury or death resulting from the lack of adherence to this critical safety requirement.
We are no longer able to recommend the following Plasma Cutters as compatible with the CrossFire.
Interference generated by the power supplies of these cutters have been known to cause issues with CrossFire electronics. Owners of these models who wish to use their cutter with the CrossFire must take further steps to ensure proper grounding and resistance to EMI in their systems.
Use of these cutters is not supported by Langmuir Systems and is at your own risk.
The same blow-back start plasma cutters that are compatible with the CrossFire are compatible with the PRO and XR. The torch lead must be at least 16’ long to be used on the PRO and 25' long to be used on the XR. If your torch lead is shorter than necessary, contact your plasma cutter manufacturer to see if they can supply a torch with a longer lead.
Razorweld Plasma cutters purchased elsewhere are compatible with CrossFire CNC machines. However, users will likely have to wire these cutters for torch firing and THC voltage manually as these cutters are likely not Plug-and-Play despite having similar ports.
