You are bidding on a used unit. I have not tested it because I'm not sure how to use it, however everything seems to be all there and in great shape. It also comes with the manual. ELECTRO-CHEMICAL MARKING is the process used for stress free permanent marking on all conductive metals. The process is economical, simple, fast and safe. The one restriction to this process is that it will not function on painted parts, already anodized aluminum or through certain heavy phosphate coatings. However, by deep etching the parts prior to any of these non-conductive coatings, the mark shows through very legibly. This allows positive traceability throughout the life of the parts. MARKING METHODS’ complete MARK 300 (SERIES) Electro-Chemical marking system is designed to provide maximum performance and ease of operation. The assembly includes all the necessary equipment and supplies to most effectively mark all parts....from tiny semiconductors to massive aircraft and aerospace components. Depth of mark from one ten thousandth (.0001) of an inch deep for feeler and plug gages to ten thousandths (.010) deep for absolute traceability of parts is easily attainable. The power unit is equipped with an AC-DC switch. The AC (alternating current) alternately etches out and redeposits back a combination of the metal oxide and electrolytic salts producing a black mark. The DC (direct current) charges the applicator negatively (cathodic) which dissolves metal out, etching a frosted or clear mark. To prevent corrosion, the parts must be thoroughly cleaned after marking to remove any residual salts. No special skill is required to operate the equipment except pride in doing a good job. Electro-Chemical marking does not deform, weaken or fracture the metal because molecular structure is not altered beyond the depth of the mark. Methods such as steel stamping, electric arc etching or vibratory marking alter the grain structure of the metal in the area of the mark causing possible stress or fracture to the parts.
