A professional who operates mechanical units of automated production machinery to produce deposited carbon resistors for use in electronic equipment. Respnsibilities include:

• Turns valves to admit methane and nitrogen gases into carbon-coating furnace and sets furnace temperature for computer control according to work order.
• Presses buttons and turns valves to start vacuum pump of terminating chambers and set rate for back-filling chambers with argon gas, preparatory to sputtering gold contacts on carbonized ceramic cores.
• Sets thermostats to heat curing oven of encapsulating machine and water vat of air-leak detection unit to specified temperatures.
• Turns valve to spray water over resistors emerging from curing oven.
• Observes temperature gauges, pressure gauges, and machine operation to detect mechanical failures in automated machinery.
• Notifies maintenance mechanic of machinery malfunction.
