A stick welder is a type of welding machine that uses an electric current to create heat, melting a metal rod, known as an electrode, to join two pieces of metal together. The electrode is coated with a flux that helps protect the weld from contamination and improves the quality of the bond. This method is commonly used in construction and repair work due to its versatility and portability. Stick welding is also known as shielded metal arc welding (SMAW). It is suitable for various metals, including steel and iron, and can be performed in different positions, such as flat, horizontal, or vertical. This makes it a popular choice for both professional welders and DIY enthusiasts.
