Low voltage electrical based parts-in-place (pip) system for contact start torch |
摘要 |
A detection system for a cutting torch for use in connection with a workpiece. The detection system has an electrode and a tip. A housing supporting the tip and the electrode provides relative movement therebetween and allows electrical contact between the tip and the electrode. A sensor circuit senses when the electrode and the tip are in electrical contact. The sensor circuit generates a switch control signal when the electrode and tip are in electrical contact. A power supply provides a first voltage and a second voltage such that a potential voltage difference is established between the electrode and the and/or workpiece. A magnitude of the first voltage is less than a magnitude of the second voltage. A first switch selectively provides the second voltage to the electrode in response to the switch control signal whereby the potential voltage difference between the electrode and the tip and/or workpiece corresponds to the second voltage when the switch control signal indicates that the electrode and tip are in electrical contact. |
