於ける安全監視装置。[Scope of Claim for Utility Model Registration] A safety monitoring device used in a core plasma cutting device having a plasma torch, which comprises a pressure switch provided downstream of a working gas control valve, comprising: ON-OFF detection means for a cutting power source; Overheat detection means of the cutting power supply, overcurrent detection means of the cutting power supply, ON-O of the shield cup of the plasma torch
The signals from the four detection means of the FF detection means are used as the condition for determining whether to turn on the plasma torch switch.
After the torch switch is turned on, signals from the four detection means and the pressure switch are turned on.
- A safety monitoring device for an air plasma cutting device, characterized in that the plasma cutting power supply device can be activated only when the AND of the signals from the OFF detection means is established.
