- Review engineering blueprints, install air conditioning direct expansion and chilled-water systems, test systems for proper functioning, reviews and adjusts system controls, using Direct Digital Control (DDC) computer system, perform emergency repairs, maintain tools, order supplies, and making routine adjustments to maximize operational efficiency.
- Analyze data when inspecting systems, for temperature, fuel consumption, hours of operation, etc.
- Perform minor repair of DDC components. Recover and properly dispose of refrigerants (Ozone Depleting Substance) when servicing air conditioning equipment.
Heating & Boiler Equipment Mechanic Duties:
- Installs, maintains, and repairs a variety of complex industrial equipment and systems involving power steam, high, medium and low pressure and temperature boilers with complicated components, critical requirements, and rigid tolerances, using specialized test equipment.
- Incumbent repairs, troubleshoots, and maintains single-and-multiple fuel power boilers and associated auxiliary and pollution control equipment such as, industrial water treatment systems, chemical dispensers, electrostatic precipitators, bag houses and ash removal equipment, and wet particulate scrubbers.
- Reviews and adjusts system controls, using Direct Digital Control (DDC) computer system.
Industrial Equipment Mechanic Duties:
- Installs, aligns, troubleshoots, repairs, overhauls, and maintains various types of nonproduction industrial plant machinery, equipment, and systems.
- Contractor disassembles and repairs general industrial plant machinery, equipment, and systems such as, towveyor and conveyor systems, bridge cranes, air compressors, engine and hydromatic dynamometers, and similar equipment.
Electronics Mechanic Duties:
- Installs, modifies, overhauls, maintains, troubleshoots, and repairs electronics equipment of moderate complexity or a system of limited complexity.
- Follows blueprints and manufacturers' specifications, uses hand tools and specialized test instruments. Electronic equipment serviced is usually self-contained and functionally independent such as, color radar receivers and transmitters, video recorders, color video cameras/recorders, audio recorders, two-way radios, multichannel very high frequency (VHF) or ultra-high frequency (UHF) transmitters or receivers, power supplies, and multilayered printed circuit boards.
- Representative of systems of limited complexity are: public address, security monitoring and access systems, closed circuit TV monitor systems, and personal computer systems.
- Sets-up and operates computer controlled automatic test equipment to test and troubleshoot various components and assemblies of electronic equipment or printed circuit boards.
- Calibrates testing instruments and maintains records of repairs, calibrations and tests.
- Welds a variety of metals and alloys. Uses a variety of manual welding processes, e.g., several different gas torch processes, various electric arc processes including inert gas shielded, or a number of both kinds of processes, to weld all types of metals and alloys of various sizes, shapes, and thicknesses, including dissimilar metals such as, copper to steel.
- Processes used are: oxyacetylene, oxyhydrogen, and other industrial gases. The arc processes used (including inert gas-shielded ones) involve methods such as, gas metal-arc, gas tungsten-arc, gas carbon-arc, plasma-arc, and atomic hydrogen welding.
- Welds in hard to reach places that must meet close tolerance, strength, and other requirements e.g., evenness of fit and smoothness of contour. Plans work by interpreting blueprints, determine welding position and type of metal to be fused.
- Selects and set up welding equipment and ensure welds meet standards and engineering design drawings and specifications.
Sheet Metal Mechanic Duties:
- Develops patterns and lays out, cuts, forms, joins, assembles, and installs items such as, heating, air conditioning, and ventilating pipes; conduits; drying ovens; bulkheads; airframes; spars; air scoops; control and flying surfaces; and other items and systems with combined straight and curved edges or irregular angles, planes, and curves.
- Plans, lays out, and constructs manufactured items and systems with dovetailed, set-in bottom, burred-bottom, wired, or lock seams. Works with various metals, including magnesium, honeycomb material, alloys, stainless steel, and copper sheet.
- May perform maintenance work in other trades not requiring journey level skills in trades such as, Carpentry, Plumbing, Machining, Masonry, or Painting.
