AC vs DC Stick Welding

Stick welding, also known as Shielded Metal Arc Welding (SMAW), can be performed using either AC (Alternating Current) or DC (Direct Current) power sources. Both AC and DC stick welding have their own advantages and applications.

AC Stick Welding

In AC stick welding, the power source alternates the direction of current flow at a specific frequency. This back-and-forth current flow allows for effective welding of various types of metals, including steel, cast iron, and aluminum.

AC stick welding offers several benefits:

DC Stick Welding

In DC stick welding, the current flows in one direction, either positive (DC+) or negative (DC-). DC stick welding is commonly used and offers its own set of advantages:

Choosing Between AC and DC Stick Welding

The choice between AC and DC stick welding depends on several factors:

It is recommended to consult welding experts, follow manufacturer guidelines, and consider the specific requirements of your welding project to determine whether AC or DC stick welding is the most suitable choice.
