Material Thickness and Joint Design The physical properties of the workpiece should heavily influence your choice of current. Best Practices and Final Recommendations.
Leveraging AC Balance for Superior Steel Cleaning Action
For thin gauge steel, such as automotive panels or sheet metal, the cleaning action of AC can prevent porosity and ensure a smooth, shiny weld. AC is the standard for welding aluminum and magnesium, but it is also beneficial for certain steel applications, particularly when surface preparation is critical.
While the question of AC or DC might seem simple, the answer depends heavily on the specific type of steel, the thickness of the material, and the desired outcome of the weld. Understanding the Fundamentals of Current Flow To decide between AC and DC, it is essential to first grasp how these currents interact with the tungsten electrode and the metal itself.

This provides deep, focused penetration, making it ideal for thicker materials where you need to drive heat efficiently through the joint. In DC welding, the electron flow moves in a single, constant direction.
