| − | The pressure regulators enable the user to reduce the high pressure contained in the cylinder to a usable working pressure. There are several handling and set up procedures that are important to the overall operation of the pressure regulator. The pressure regulator on each tank shows two things:

| − | * Before installing the regulator, crack the cylinder valve to clean out any dirt or dust.
| |
| − | * Mount the regulator onto the cylinder.
| |
| − | * Ensure that the oxygen pressure regulator is on the oxygen tank.
| |
| − | * Do not over tighten regulator nut.
| |
| − | * Before opening the cylinder valve ensure that the pressure regulator screws are released (turned out).
| |
| − | * Never use oil or grease on the regulators.
| |
| − | * Frictional heat as a result of high pressures can cause oil to ignite and possibly cause an explosion.

| − | Electric arc welding does not use gas to produce a weld like oxy-acetylene welding does. Electric arc welding uses an electric current to produce its welds. A clamp, with the one side of the current flowing through it, is attached to a base plate. Then the another clamp/nozzle, with the other side of the current flowing through it, is held in a hand. A filler rod is then used to complete the circuit and create the heat needed to heat the pieces of metal being joined and melt the filler rod (used to bind the pieces of metal together).

La soldadura esencialmente toma el lugar de pernos y remaches, y si no se realiza correctamente, es muy peligrosa. Ejemplo: Un remolque o una maquinaria que no se enganche en condiciones apropiadas, expuesta a la tensión de la tracción o el peso, son una invitación al desastre. --> |

Welding essentially takes the place of bolts and rivets, and if not properly done, is most dangerous. Example: A trailer hitch not properly bonded, or machinery exposed to the strain of pull or weight, is an invitation to disaster. <br>Note: This requirement demonstrates one's skill in working in darkness, such as in an emergency. All acetylene connection threads are left-handed, while all oxygen connection threads are right-handed. --> | |
