Compare AC and DC Electric Arc Welding: Key Differences, Pros and Cons Explained
DC electric arc welding uses a stable direct current, reducing defects such as spatter and porosity. In contrast, AC electric arc welding uses alternating current, leading to variable polarity. Generally, DC welding is preferred for most jobs due to its efficiency and cleaner results, while AC welding is useful for certain specific applications. AC welding … Read more
