Wind and splice wires at different lengths for different jobs.
Controls equipment to produce vinegar: Starts pumps and opens valves to charge generators and concentrators with specified volume of vinegar starter, water, alcohol, and coolant. Monitors air and temperature gauges and flowmeters and adjusts thermostats, valves, and dials to maintain prescribed generating and concentrating conditions for strength of vinegar being processed. Turns valves to regulate rate and volume of solution through filter tank and to transfer solution to storage or shipping tank. Tests vinegar samples for grain content, using pH meter and hydrometer. Records test results and air temperature readings on process control cards.
