PRO CNC Plasma Instructions

Our PRO CNC Plasma systems are currently compatible with Hypertherm 45XP, 65, 85, and 45 (discontinued) systems. These torches are available from a number of sources, although we recommend Baker's Gas if you are ready to purchase. To work with our torch mount, Ohmic touch-off and torch height control system, the Machine Torch, and CPC options are required. Shielded (Mechanized) Consumables are required for use with machine torch systems.

In order to work with the Ohmic touch-off feature that comes standard with our torch mounts, an ohmic retaining cap (sold separately) is required. Below are links to compatible configurations of Hypertherm torches and retaining caps.

Recommended Torches and Retaining Caps:
Plasma Setup
The following steps and downloads are required to set up plasma on your machine:
  1. Follow the instructions in our Getting Started Guide for mechanical setup and wiring of the plasma components.
  2. Download the Custom Merge Files, THC Plugin and Plasma Screenset for plasma
  3. Follow the instructions in our Plasma Software Setup and Usage Guide to install the files you just downloaded. This manual is also a helpful reference for plasma-specific software features like torch height control and anti-dive
  4. Follow the instructions in our Plasma Retrofit Guide to install your Torch Height Control card (not necessary if purchased with CNC Router Parts electronics) and update Mach 3 settings for plasma.
  5. Install the Post processor for SheetCAM, which adds a material touch-off of material to the beginning of each pierce. The link contains both an Ohmic touch off post (recommended for most applications), or a Mechanical touch off post using the floating head switch (recommended only for special applications like rusty materials)
  6. Go through our Operation Checklist before cutting on the machine to insure successful operation.
  7. For advanced troubleshooting of torch height control and anti-dive settings, the THCLogAnalyser application can provide helpful information and visualization of log data.
