Previous generation
BX17 arc generator
The BX17 is the generator the first customers have been cutting with for years. It speaks ASCII over RS-485 and sends an analog differential speed command to the motion controller. It is straightforward to use with a CNC that can move backwards, such as Dynomotion. It is no longer sold.
Features

- Fully configurable arc parameters
- Arc current up to 30 A
- Cutting frequency up to 200 kHz
- ISO-frequency mode and ISO-pulse mode
- Single-shot mode from an optically isolated external trigger
- Analog differential speed command for CNC feed control
- Differential sense input for arc voltage
