MSSC MAINTENANCE AWARENESS EXAM
2024-2025
15 psi is the maximum pressure for acetylene gas.
ANSWER for oxygen cylinders Should be kept at least 20 feet away from
combustible materials.
ANSWER: An oxygen cylinder should be fully open. To prevent leakage around
the valve when in use.
Acetylene - Answer The red welding pipe attached to a torch rig.
Oxygen - ANSWER Green welding hose on a torch rig.
Torches employ reverse-flow check valves at torch inlets or standard
outlets—answer To avoid combining oxygen with acetylene.
DC (Direct Current) - Answer The type of current that runs in only one direction is
___.
AC (Alternating Current) - Answer Circuit testers determine whether ___ is
present.
Input Device - Answer The ___ is the component of an electrical circuit that allows
the operator to control it.
Components are represented with standard symbols, which shows how the
components are interconnected and is useful for diagnosing circuits. - ANSWER
An electrical schematic does the following.
, Normally Closed (NC) - Answer. When the operator operates on a ___ switch, its
contacts become open.
Motor, lamp, and resistor - ANSWER Each of the following are electrical output
devices:
Motor - ANSWER A ___ is an electrical output device that generates rotating
motion.

Potential Difference: ANSWER Both analog and digital voltmeters measure ___.
Across a component, from a reference - ANSWER There are two ways to measure
voltage:
ANSWER: Voltage, Current, and Resistance A multi-meter is a versatile gadget
that can measure;
A parallel circuit provides many paths for current to travel.
Equal to the power supply voltage. In a parallel circuit using a constant voltage
power supply, the voltage across each branch is ___.
A current value, for example, is 10 ma.
