Abstract
A shield cup protector apparatus for protecting a ceramic shield cup of a plasma arc torch from breakage during operation thereof. The shield cup protector apparatus is comprised of an elongated cylinder having first and second open ends. A first open end of the elongated cylinder is positioned to abut a peripheral portion of the shield cup, allowing the shield cup to extend into an inner cavity formed by the cylinder, thereby allowing the shield cup to support the cylinder therefrom, while also allowing the elongated cylinder to surround the exposed surfaces of the shield cup to protect the shield cup thereby.
