15 – Oxyfuel Application
Controlling proportional gas regulators with analog outputs
Hypertherm CNCs provide analog outputs that can control proportional gas regulators. Using this strategy allows you to
reduce the number of regulators needed for the gas delivery system from six as shown earlier in this section, to three as
shown below. Analog outputs are available for three channels: fuel gas, preheat oxygen, and pierce/cut oxygen.
Setting up your oxyfuel cutting system in this manner requires a SERCOS drive system to control the extended number
of analog outputs.
