Assembles electric-motor control units, such as transmitters, relays, switches, voltage controls, and starters and mounts unit on panel according to drawings and specifications, using handtools and power tools: Cleans parts, using liquid cleaner, airhose, and cloth. Assembles units, using handtools, pneumatic nut runners, power press, and torque wrenches. Lays out and drills mounting holes and mounts units to panel, using scribers, rule, dividers, drill press, portable power drill, reamer, screwdrivers, and wrenches. Adjusts and aligns parts to maintain specified airgap, contact wipe, dimensions, and part movement, using feeler gauges and micrometers. Solders electric wire connections and secures spring guides, setscrews, and spring post to units, using soldering iron and acetylene torch. Tests electrical circuits for resistance, current, and potential difference, using instruments, such as ohmmeter, ammeter, and voltmeter. May be designated according to control assembled as Transmitter Assembler; Voltage-Regulator Assembler. May also operate sheet metal forming machines to fabricate housing for synchro-units and be designated Synchro-Unit Assembler.
