AI Technical Summary
Technical Problem
In existing plasma cutting systems, gas pressure control is affected by electromagnetic interference (EMI), resulting in inaccurate gas pressure regulation and affecting cutting quality.
Method used
The pneumatic guide regulator and three-way valve combination is used to achieve almost instantaneous control of the processing gas pressure through the pneumatic control system, independent of the electronic control system, and avoid EMI interference.
Benefits of technology
Accurate and almost instantaneous control of the gas pressure of the plasma welding torch is achieved, reducing wear of electrodes and nozzles, and improving cutting quality.

Abstract
A pneumatic system for nearly instantaneous control of process gas for an arc process torch. The pneumatic system comprises an electropneumatic regulator and a three-way valve for pneumatically controlling a pilot signal for the pilot regulator. The pilot regulator controls the pressure of the process gas supplied to the arc process torch.
