Understanding Cutting with an Arc Welder
An arc welder is primarily designed for welding metal pieces together. However, with the right setup and technique, it can also be used as a cutting tool. This method is commonly known as arc cutting, or sometimes as arc gouging.
How does arc cutting work?
Arc cutting involves creating an electric arc between the workpiece and a consumable electrode, similar to arc welding. The difference lies in the technique and setup used. Instead of melting the base metal to join two separate pieces, the electric arc is used to melt and remove metal in a controlled manner, resulting in a cut rather than a weld.
During arc cutting, a high current is passed through the electrode to create the arc. The intense heat generated by the arc melts the metal, and a compressed air jet blows away the molten metal, leaving a clean cut. The process is similar to plasma cutting, but with arc cutting, a higher amperage is used, resulting in a wider and deeper cut.
Benefits and limitations of using an arc welder as a cutter
Using an arc welder as a cutter can be advantageous in certain situations:

Comparing Arc Welding and Cutting Techniques
Arc welding and cutting are two distinct techniques that require different tools and methods. While both use an arc to generate heat, they serve different purposes and require specific equipment. Let’s explore the differences between these two processes:
- Arc welding: Arc welding is a joining process that fuses metals together. It uses an electric arc formed between an electrode and the base metal to create a molten pool. As the metal cools, it solidifies and forms a strong bond. This technique is commonly used in construction, fabrication, and repair work.
- Arc cutting: Arc cutting, on the other hand, is a metal removal process. It uses an electric arc to melt and remove metal, creating a cut. Arc cutting is different from other cutting methods, such as sawing or shearing, as it produces a narrow, localized heat-affected zone. This technique is often used in metal fabrication and demolition.
While both processes utilize an electric arc, the equipment used and the techniques involved are distinct:
