The book is self-described as: "intended to assist welders in selecting and preparing one of the most important and frequently overlooked welding process variables: the electrode. Welders can spend thousands of dollars on welding equipment, but if they do not select and prepare their electrodes with this less expensive process component properly, then their welding results can be poor, inconsistent, or problematic. This guide will help eliminate this variable as a concern in your welding and make it an asset."
