The Advantages of Using AC/DC TIG Welding Machines for Aluminum Projects Aluminum is known for its lightweight and corrosion-resistant properties, but it also presents unique challenges during the welding process. The oxide layer on aluminum melts at a much higher temperature than the base metal, making it difficult to achieve a strong bond without proper preparation. This is where the AC/DC TIG welding machine shines. The AC mode generates a cleaning action during...
