A Guide That Differentiates Between DC And AC TIG Welder

Introduction:

If you are looking for a versatile and precise welding process, then the AC TIG Welder technique is quite good. However, it’s a bit different from the DC TIG welding process. Here is the read that helps differentiate between both.

What Is AC TIG Welding?

AC TIG welding is a welding technique that uses altering current. It even changes its direction and polarity within frequencies. The AC welding process is useful on aluminium and magnesium alloys. It can easily weld magnetic materials without arc blow problems. In fact, it doesn’t let any voltage drop when using long leads.

What Is DC TIG Welding?

This type of welding technique uses direct current that flows in one direction. It even has constant polarity. DC welding process is more commonly used than AC TIG welding. It is useful on most metals but not on aluminium and magnesium alloys. DC welding is a smoother and more stable arc offering high-quality welds. It, in general, produces more heat at the electrode tip and ensures better cleaning action on metals with coatings or oxides.

The Final Verdict:

Whether you are a hobbyist or a professional welder, you must know different welding processes. The difference mentioned above between AC TIG welder and DC welder process will help guide the right choice of welding equipment later. If you think which is better, then only the type of metal you want to weld will help you make quite good decisions.
