Fusion welding machines come in various types, each tailored for specific applications, including MIG (Metal Inert Gas), TIG (Tungsten Inert Gas), and arc welding systems. Each type of machine varies not only in its design but also in its price range. For instance, entry-level machines suitable for hobbyists and small-scale operations can start as low as $300 to $1,500. In contrast, industrial-grade machines, which offer advanced features and higher efficiency, can range from $3,000 to over $20,000, depending on the specifications and the manufacturer.
