Set up or set up and operate soldering or brazing machines to braze, solder, heat treat, or spot weld fabricated metal products or components as specified by work orders, blueprints, and layout specifications.

Selects torch tips, alloy, flux, coil, tubing and wire, according to metal type and thickness, data charts, and records. Sets dials and timing controls to regulate electrical current, gas flow pressure, heating/cooling cycles, and shut-off. Connects, forms, and installs parts to braze, heat-treat, and spot-weld workpiece, metal parts, and components. Positions, aligns, and bolts holding fixtures, guides, and stops onto or into brazing machine to position and hold workpieces. Cleans, lubricates, and adjusts equipment to maintain efficient operation, using airhose, cleaning fluid, and hand tools. Examines workpiece for defective seams, solidification, and adherence to specifications, and anneals finished workpiece to relieve internal stress. Disconnects electrical current, and removes and immerses workpiece into water or acid bath to cool and clean component. Operates and trains workers to operate heat-treating equipment to bond fabricated metal components according to blueprints, work orders, or specifications. Manipulates levers to synchronize brazing action or to move workpiece through brazing process. Assembles, aligns, and clamps workpieces into holding fixture to bond, heat-treat, or solder fabricated metal components. Starts machine to complete trial run, readjusts machine, and records setup data. Fills hoppers and positions spout to direct flow of flux, or manually brushes flux onto seams of workpieces.

Mechanical -- Knowledge of machines and tools, including their designs, uses, repair, and maintenance.

Operation and Control -- Controlling operations of equipment or systems. Equipment Selection -- Determining the kind of tools and equipment needed to do a job. Quality Control Analysis -- Conducting tests and inspections of products, services, or processes to evaluate quality or performance.

Control Precision -- The ability to quickly and repeatedly adjust the controls of a machine or a vehicle to exact positions. Manual Dexterity -- The ability to quickly move your hand, your hand together with your arm, or your two hands to grasp, manipulate, or assemble objects. Information Ordering -- The ability to arrange things or actions in a certain order or pattern according to a specific rule or set of rules (e.g., patterns of numbers, letters, words, pictures, mathematical operations). Problem Sensitivity -- The ability to tell when something is wrong or is likely to go wrong. It does not involve solving the problem, only recognizing there is a problem. Written Comprehension -- The ability to read and understand information and ideas presented in writing.

Handling and Moving Objects -- Using hands and arms in handling, installing, positioning, and moving materials, and manipulating things. Controlling Machines and Processes -- Using either control mechanisms or direct physical activity to operate machines or processes (not including computers or vehicles). Performing General Physical Activities -- Performing physical activities that require considerable use of your arms and legs and moving your whole body, such as climbing, lifting, balancing, walking, stooping, and handling of materials. Inspecting Equipment, Structures, or Material -- Inspecting equipment, structures, or materials to identify the cause of errors or other problems or defects. Monitor Processes, Materials, or Surroundings -- Monitoring and reviewing information from materials, events, or the environment, to detect or assess problems. Getting Information -- Observing, receiving, and otherwise obtaining information from all relevant sources. Repairing and Maintaining Mechanical Equipment -- Servicing, repairing, adjusting, and testing machines, devices, moving parts, and equipment that operate primarily on the basis of mechanical (not electronic) principles. Evaluating Information to Determine Compliance with Standards -- Using relevant information and individual judgment to determine whether events or processes comply with laws, regulations, or standards.
