Tanking, Drying, and Filling Technician at WESTRAFO AMERICA LLC – Trotwood, Ohio

PURPOSE:

Westrafo America is a new manufacturing facility specializing in the production of electrical transformers. We are building a high-performing team focused on safety, quality, and operational excellence.

The Tanking, Drying, and Filling Technician is responsible for installing transformer cores and coils into tanks, performing vacuum drying operations, and filling completed units with insulating fluid according to engineering and quality requirements. This role plays a critical part in ensuring transformer reliability by maintaining proper moisture removal, vacuum integrity, and oil-processing standards.

Duties:

Tanking Operations:

• Prepare transformer tanks by verifying cleanliness, proper sealing surfaces, and readiness for core-and-coil installation.
• Install cores, coils, insulation assemblies, and accessories into the appropriate tank following engineering drawings and work instructions.
• Use cranes, rigging, and lifting devices to safely handle heavy components.
• Fit gaskets, seals, hardware, and other components to ensure proper tank assembly before drying.

Drying & Vacuum Operations:

• Operate oven-drying systems, vapor-phase drying units, or vacuum drying equipment depending on transformer type.
• Monitor temperature, drying cycles, and vacuum levels to ensure proper moisture removal from windings and insulation systems.
• Record process parameters and verify compliance with specifications.
• Inspect for leaks, improper seals, or vacuum loss; perform corrective actions as necessary.

Oil Processing & Filling:

• Prepare and maintain transformer insulating fluid (oil) to required purity levels, including degassing, filtering, and moisture testing.
• Operate oil-processing and transfer equipment to fill transformers under vacuum.
• Monitor fill levels, pressure changes, oil temperature, and flow rates.
• Perform post-filling checks, including leak inspection, top-off, and sampling for moisture/quality testing.

Quality & Documentation:

• Complete all production documentation, traveler steps, test logs, and inspection forms accurately.
• Ensure proper traceability for oils, materials, and processing cycles.
• Communicate issues with tank fit, vacuum performance, drying anomalies, or oil contamination to supervisors or engineering.
• Support internal audits and quality inspections as required.

Safety & Equipment Care:

• Follow all safety procedures related to crane operation, hot surfaces, confined spaces, and pressurized/vacuum systems.
• Use PPE such as gloves, respirators, face shields, and protective clothing when handling oils and chemicals.
• Maintain equipment cleanliness, perform basic maintenance checks, and report equipment abnormalities.
• Ensure adherence to spill-prevention and environmental handling requirements for insulating fluids.

• High school diploma or GED preferred.
• 1-3 years of industrial manufacturing or mechanical equipment experience.
• Ability to operate overhead cranes, rigging equipment, and lifting devices safely.
• Basic understanding of vacuum systems, drying ovens, pumps, and fluid processing equipment.
• Ability to read engineering drawings, work instructions, and production travelers.
• Strong attention to detail and commitment to quality.
• Comfortable working with oils, chemicals, and high-temperature equipment.
• Experience in transformer manufacturing or high-voltage equipment preferred.
• Familiarity with ISO 9001, lean manufacturing, or 5S practices preferred.
• Basic mechanical understanding is required.
• Frequent standing, bending, climbing, and handling of heavy materials with assistance from cranes and rigging.
