Abstract:
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, contacting a proximal end of the electrode body, is used for imparting a separation force to the electrode body. The electrode body is adapted to overcome the separation force and engage a contact element of the torch when the torch is operated in a transferred arc mode.
