An AC stick welder will give you the most reliable and efficient weld. It also has a greater degree of control over the thickness of the weld.

DC rod sticks are very good for the small-scale fabrication of small pipes and tubes. They also work well for welding a lot of sheet metal to a surface.

If you weld with an all-position rod and use a lot of sheet metal and steel in a project, you may want to consider using the AC stick welder.

Why AC Stick Welding Is the Choice of Many Welders?

The AC stick welding rod is best for high-strength, flat welds.

It has a low deposition rate and burns through the surface material. It gives the most control over the thickness of the weld. It also burns better on the inside of the weld than the DC weld sticks.

The higher temperatures, the more rapid the burn, the better the heat transfer and control of the welds, which is needed when welding corners, large areas of the frame, and when arc blow often becomes a nuisance is where AC stick welding proves invaluable.

When is AC Stick Welding Needed?

Many times, in metalwork, situations arise when welders can benefit from AC polarity, especially when the only available output in the power supply is AC output.

Such situations often occur when entry-level welding machines are used. Apart from this, there are certain technical situations such as arcing (associated with the use of DC polarity) when AC wand welding is required.

When welding, welders always want to focus the arc (which has a shape) directly into the joints in order to achieve the full penetration necessary for effective welding.

However, if an arc is blown, welders will want to address this problem because it can damage the surface. The most effective way to deal with arc blow is to switch to AC polarity.

As the AC polarity changes from negative to positive, welders can weld magnetized parts.

You should know about the characteristics and advantages of the different AC welding rods before you decide to buy one. There are more welding rods on the market than the typical 1.8 in. to 5/32 in. Thickness.

The AC (all-position) rods are used for the widest array of applications and for the highest degree of control.

AC welding rods are most commonly used in shipbuilding, automotive manufacturing, and many other fields where managing arc blow proves to be a challenge.

AC stick welder is also required for piping or structure work.

Other Problems Associated with DC Stick Welding

The DC rods have a high deposition rate and can’t penetrate deep enough in the metal. They can handle thinner wire and smaller wire gauge welding, but the AC stick rod does a better job on thicker sheet metal.


So, do you need a DC or AC stick welder? The answer is yes! There are many cases where welders prefer AC stick welding to DC for the many reasons we discussed above.
