Etching Electrode Prevents Arcs
Wooden part replaces stainless-steel part. Disposable electrode for etching Inco(R) 625 (or equivalent) alloy works better than previous, more expensive version. Size and shape of electrode makes it easier than before to etch in narrow grooves and other confined spaces. Designed to prevent arcing, which damages metal workpiece.
