![]() This is essential because it helps complete the electrical circuit that will create the arc, which is used to join the two pieces of metal together.ģ. Placing an electrode lead against the welding material – When the welder is ready to begin the welding process, they will place a highly-conductive electrode against the welding material and activate the machine to send electrical current through the workpiece. This attaches directly to the welding machine. It’s important to read the manual provided by the manufacturer thoroughly to set up an arc welder properly.Ģ. Grounding the welding material – Once the welder is ready to begin the welding process, they will attach a ground clamp to the metal workpiece. Various controls can be used to change the power of the machine and how it operates. Ready to dive into the details? Here’s a step-by-step guide to how an arc welding machine works.ġ. Setting up the machine – To begin, the welding machine must be set up. How an Arc Welding Machine Works – Step-By-Step Let’s take a deeper look at this process and how an arc welding machine works now. This arc heats the metal to an extremely high temperature, melting both the electrode and the metal it’s touching, creating a weld pool that allows the two metals to be joined. In this case, that’s the metal workpiece and the electrode, both of which have a strong electrical current fed to them through the welding machine. Arc welding technology uses a high-powered electrical “arc” to melt a metal workpiece that’s grounded to the welding machine, and an electrode that’s also attached to the welding machine.Įlectrical arcing occurs when electric current “jumps” and flows through the air between two conductors. However, arc welding is, by far, the most common type of welding, so that’s what we’ll talk about in this guide. But this is a relatively uncommon type of welding technology today. In torch welding, for example, a high-powered torch is used to melt the workpiece and a metal welding rod to join the metals together. Understanding the Basics of Arc WeldingĪrc welding is not the only type of welding. Read on and learn everything you need to know about modern welding technology. In this blog from Vern Lewis Welding Supply, we’ll discuss the basics of arc welding and how a welding machine works – so that you can understand the fundamentals of the process. If you’re new to the world of welding, or you just want more information about how arc welding works, you’re in the right place.
