AC/DC capability greatly expands the versatility of a TIG welder. DC mode is best for welding steel and stainless steel, providing a stable arc and cleaner welds. AC mode is essential for welding aluminum and magnesium, as it allows for the cleaning action needed to break up oxide layers. Choosing a welder with both AC and DC modes means you’re not limited to one type of material. The Lincoln SquareWave TIG 200 and Lincoln Aspect 375 AC/DC TIG Welder Ready-Pak both support AC/DC welding, giving users maximum flexibility. Many models offer either DC-only or AC/DC capability, so you can select the best fit for your application.
