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. The electrode and torch can include a contact element having a first surface in electrical communication with the power contact and a second surface characterized by (i) physical contact with the electrode body during transferred arc mode and (ii) absence of physical contact with the electrode body during initiation of a pilot arc.
