  When you start TIG welding, the first major setting you have to set up is the current. Using AC or DC has a hugh impact on your weld results. In this article I will give you a best practice guideline that should help you make the right choice for your welding tasks in the future.  TIG welding  can be done with both, alternating current (AC) or direct current (DC). The type of current to choose depends on the workpiece material. Generally, Steel would be welded with DC and Aluminium with AC. In the following sections, I will get into a more detailed answer, which should enable you to make the right choice with ease, the next time you have to pick a type of current for your weld job.    AC, DC, whats the difference? In case you are not familiar with the terms AC and DC yet, they describe the way electricity is flowing. Electricity is a stream of electrons, comparable with water in a river. In this example, a river would be a direct current power source. Water is only flowing downstream

  Mig-Mag Welding Machine   There are a number of methods and processes welders can employ when they’re working on projects. One of the most common welding processes is known as gas metal arc welding (GMAW). During this process, an electric arc forms between the metal being worked on and a wire electrode. Heat is applied to the pieces and helps melt and fuse them together, forming a permanent bond. GMAW can be split into two main welding categories, metal inert gas (MIG) and metal active gas (MAG). When it comes to MIG versus MAG welding, the biggest difference is the type of gas used during the process. Only inert gases that don’t experience chemical reactions are used in MIG welds, like helium, argon or a mix of the two. Active gas mixtures like carbon dioxide (CO2) or oxygen mixed with argon are utilized in MAG welds. Curious to find out more about the specifics of MAG welding?
