Electrode for a Contact Start Plasma Arc Torch and Contact Start Plasma Arc Torch Employing Such Electrodes |
摘要 |
An electrode for a contact start plasma arc torch includes an elongated electrode body formed of an electrically conductive material. The electrode body is movable relative to the torch. A resilient element is used for passing substantially all of a pilot arc current between a power supply, a power connection in electrical communication with the power supply, and the electrode body during pilot arc operation of the plasma arc torch. The electrode and torch can include a contact element having a first surface in electrical communication with the power contact and a second surface for physical contact and electrical communication with a corresponding contact surface of the electrode body for passing substantially all of a transferred arc current between the power supply and the electrode body during transferred arc mode. |
