A Gas Cutter uses oxy-fuel torches to precisely cut, shape, and dismantle metal for fabrication, construction, or scrap processing, focusing on safety (PPE, fire prevention), interpreting blueprints, setting up equipment (cylinders, hoses, tips), and ensuring accuracy while working with various metals like steel, often in conjunction with welders or machine operators. Key tasks involve marking material, adjusting gas flow, guiding the torch (manual or automated), and maintaining equipment to meet specs.
