Pot
Pot turns up in 2 fields: thermal spray, electronics. Here is what it means to the people in each one.
Pot in thermal spray
Shop name for the pressure blast vessel that holds grit and feeds it into the blast hose.
Pressurized tank, sometimes called a blast pot, that holds abrasive and meters it into a stream of compressed air through a mixing valve. Pressure pots blast faster and harder than suction cabinets and are used for large parts and field work. Wet air in the pot makes grit clump and surge, so a moisture separator or dryer upstream is standard.
"Pot's surging again, there's water in the grit, drain the separator before you open it up."
Pot in electronics
A common shorthand for a potentiometer used to adjust resistance in a circuit.
A pot is a manually adjustable variable resistor with three terminals, typically featuring a rotary knob or linear slider. Technicians and engineers use this clipped term universally on the bench when referring to volume controls, trim adjustments, or user-interface dials. Depending on how it is wired, it acts as either a voltage divider or a simple rheostat.
"Just tweak that trim pot on the power supply until you get exactly 5 volts on the output."
