* Key Responsibilities:

** To perform this job successfully, an individual must be able to perform each essential duty satisfactorily. Reasonable accommodation may be made to enable qualified individuals with disabilities to perform the essential functions.
1.
** Sub Assembly Fabrication
*** Fabricate and assemble copper piping sub assemblies in accordance with engineering drawings, bills of material, and manufacturing work instructions, ensuring all dimensions and specifications are met.
* Cut, ream, deburr, and prepare piping and tubing materials to specified lengths and tolerances using handheld pipe cutters, tube saws, and cold saws.
* Identify, match, and assemble correct components, fittings, valves, and hardware to each sub assembly per drawing specifications.
* Stage completed sub assemblies in designated holding areas, to ensure smooth and timely delivery to the production line.
2.
** Soldering Operations
*** Perform both soft soldering and silver (hard) brazing operations on copper-to-copper, copper-to-brass, and copper-to-steel piping joints, fittings, and components used in refrigeration sub assemblies.
* Properly clean, flux, and prepare all joint surfaces prior to soldering — including thorough removal of oxidation, burrs, and debris — to ensure sound metallurgical bonds and leak-free connections.
* Select the correct solder alloy and flux for each application, including silver brazing alloys (e.g., Sil-Fos, Stay-Silv) for high-pressure refrigeration joints.
* Apply torch heat evenly and at the correct temperature to achieve full solder flow and proper capillary penetration throughout the joint, avoiding overheating, cold joints, flux burn, or internal oxidation.
* Purge refrigerant-grade copper lines with dry nitrogen during brazing operations as required to prevent internal oxide scale formation that can damage refrigeration system components.
* Visually inspect all completed solder and braze joints for full fill, smooth fillet formation, and absence of voids, pinholes, cracks, or excessive flux residue; rework any joints that do not meet quality standards before release.
* Maintain torch equipment, tips, hoses, and fuel connections in safe, clean operating condition; report any deficiencies or leaks to maintenance immediately.
* Adhere strictly to all fire safety protocols and housekeeping standards when operating open-flame equipment.
