The Cougartron WELC4045 Basic Etching Set is an add-on kit that transforms your existing Cougartron weld cleaner into a precision electrochemical marking / etching tool. It includes all necessary accessories (marking head, fluids, felts, carry case) to begin etching logos, serial numbers, or identification marks. It supports continuous marking or timed intervals and is compatible with all Cougartron cleaners (e.g. ProPlus). The set is compact, transportable, and useful for shops wanting marking capability without buying a full marking machine.
