A professional who tends battery of electric cells (tanks having positive and negative poles) to dissociate chemical elements from solutions. Respnsibilities include:

• Examines poles and sides of cells for defects, such as corrosion or cracks, and notifies supervisory personnel of findings.
• Opens valves to fill cells with solutions, and moves controls to start electrolytic process.
• Observes gauges and indicators on panelboard; and moves controls to maintain specified pressure, temperature, amperage, and voltage in each cell.
• Presses button to actuate automatic measuring and gas-testing device, and observes gauges that indicate gas volume and dissociation of solution in each cell.
• Records data in operational log.
