Arc welding   is a common welding process used in a variety of industries to join metals together. It involves creating an electric arc between a consumable or non-consumable electrode and the workpiece, which heats the metal and creates a molten pool. As the molten metal cools, it solidifies and forms a strong bond between the two pieces being joined. One of the key factors that affect the quality of the weld is the type of current used. In arc welding, two types of currents are commonly used - alternating current (AC) and direct current (DC). Both of these currents have their unique characteristics and can be used in different  welding applications  depending on the requirements. Alternating current (AC) is an electrical current that alternates its direction periodically, usually at a frequency of 50 or 60 Hz. AC is commonly used in welding applications where a high penetration is required, as it allows for a deeper weld pool to be formed. AC is also ideal for welding m...

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 sou...
