Portable D.C. power electro-chemical etching tool and method

摘要

A low voltage, low current power supply and chemical etching tool includes a container and a D.C. voltage source sealed within the container. The D.C. voltage source may be one or more batteries that together generate less than 18 volts and 1.7 amps. Electrical leads are connected to the D.C voltage source, and lead from the container through openings in the container cap. The electrical leads have no splices external to the container. The openings through which the electrical leads pass are sealed. One of the electrical leads is connected to an electro-chemical etching head. The other electrical lead is connected to a connecting clip to be attached to the part to be marked by the etching process.
