If you are looking for a disappointing first welding experience, buy the ER70S-3 for filler metal. The ER70S-3 wire is often referred to as having a "moderate" deoxidizer content. In reality by comparison, this is really little or none. The question of course comes immediately to mind, “Why use it?” The answer is that it is really economical to use, especially if you have exceptionally clean metal. ER70S-3 is among the cheapest wires to buy.
