A TIG (Tungsten Inert Gas) welder is a skilled professional specializing in TIG welding, a precise process using a non-consumable tungsten electrode to create an electric arc between the electrode and the metal being welded. Inert gas shields the weld area, preventing contamination. TIG welders work across diverse industries like engineering, automotive, aerospace, and manufacturing, producing high-quality welds with precision and aesthetic appeal. They interpret blueprints, set up equipment, and maintain it, possessing excellent hand-eye coordination and knowledge of various metals like stainless steel, aluminum, and copper.
Several manufacturers produce TIG welding machines, including Lincoln Electric, Miller Electric, ESAB Corporation, Fronius International, Panasonic Welding Systems, and Kemppi Oy. Key features of TIG welders include adjustable parameters for current, voltage, and gas flow, pulse welding capabilities, and high-frequency starts. These controls allow welders to tailor the welding process for different materials and thicknesses. Advanced models offer features like AC balance control, which is important for welding aluminum.
TIG welder prices vary based on features and capabilities. Entry-level machines for hobbyists can start under $500. Mid-range welders with more advanced features typically range from $869 to $1,349. Professional-grade TIG welders with advanced controls and higher amperage outputs can cost several thousand dollars. Availability is generally good, with many models available online and through welding supply distributors.
