Once the welder is set up properly, grab some scrap steel to practice welding on. We decided to use a set of notches from Silver Star Customs to illustrate our learning curve. In this picture, we jumped right in without much practice and welded up one of the notches. The gun should be positioned at a 45-degree angle, with the contact tip approximately 3/8 inch away from the surface of the steel. Use one hand to hold the gun, and the other hand to steady it.
