A plasma torch assembly that provides a removable and replaceable barrier to prevent catastrophic failure of a plasma arc torch following failure of an electrode. The torch assembly comprises the combination of an electrode body for providing an electrical path in a plasma arc torch, an electrode, and an electrode adaptor positioned between the electrode body and the electrode and formed of an electrically conductive material. The adaptor comprises an adaptor body portion having structure for removably fitting the adaptor body to the electrode body and structure for removably fitting the adaptor body to the electrode so that the adaptor forms an electrically conductive path between the electrode body and the electrode and contains features and components essential to the gas distribution.
