Sets up and operates continuous multistrand electrogalvanizing and heat-treating machine to coat
steel strip or wire with zinc, according to written specifications: Mixes chemical solutions, using
formulas. Fills cleaning, pickling, galvanizing, and waxing tanks. Charges furnace with gas or coal
to prepare for galvanizing process. Inserts wire reels and feeds wire into machine. Moves controls
on rheostats and generators to regulate movement of wire strand between reels, plating tanks, and
coils, to obtain specified thickness of coating. Adjusts controls to regulate temperature of
leadpot, cleaners, picklers, and plating tanks. Performs chemical solution tests, such as titration
tests, wire hardness tests, dip coating tests, and welding tests, to determine conformance to
specifications. Readjusts controls based on findings. Records test results. Examines coating,
washing, and alignment of wire strands visually and using micrometers to compare finished strands
with specifications. Resets and changes combs when changing width and number of strands. Replaces
