Q: In most cases, you can sign up for a physical with the same institution offering the commercial diver certification you're seeking. Along with a head-to-toe examination, you'll also be tested on your swimming abilities and cardiovascular conditioning. Having drugs, alcohol, or an infectious illness in your system can be enough to temporarily disqualify you from receiving a commercial diver certification. In this case, you'll need to retake the physical once you're clear of the offending substance. If you exhibit symptoms of asthma, claustrophobia, severe motion sickness, collapsed lung, cardiac arrhythmia, or congestive heart failure, you may be denied certification permanently. It's recommended that you submit to a dive physical before going any further, even if the dive school you plan on attending doesn't require one. You may discover that you have some type of limitation that won't allow you to pursue a career as an underwater welder. Enroll in a commercial diving academy in your state or territory and work your way through their training program. The duration of these programs vary, but most are set up to be finished in 5-6 months, or around 900 training hours. Upon completing the program, you'll be receive a valid and industry-recognized commercial diver certification. A few of the more notable commercial diving academies include the American National Standards Institute Association of Commercial Diving Educator (ANSI/ACDE), the Association of Diving Contractors International (ADCI), and Diver's Academy International. Some commercial diving academies make it mandatory for applicants to pass a written entrance exam and a dive physical before they're accepted into a specific program. This is where you'll bring your 2 newly-acquired skills, welding and commercial diving, together. The course content and length of underwater welding programs can vary greatly, but most consist of both traditional study and hands-on training in wet welding skills, and may range from 6 months to 2 years. In addition to classroom curriculum, most programs will require you to clock a certain number of dive hours (usually 20-50) in order to be approved for certification. Underwater welding schools tend to be located in cities bordering major bodies of water that have thriving fishing, transportation, and drilling industries. Most underwater welders don't start off in high-profile positions. Instead, they begin as "dive tenders," apprentices that provide assistance to experienced professionals during dives. Submit your resume, complete with your new credentials, to the company of your choice to add your name to the fold of potential hires. Coastal construction companies, engineering firms, shipbuilders, and underwater salvage teams are just a few of the contractors that work with underwater welders. Research the policies and procedures unique to the underwater welding firm you want to work for and train to these specifications. This will enable you to perform at your peak level as a dive tender. The tools you'll need to excel as an underwater welder will depend on the company employing you, the nature of the work they do, and the specific industry regulations in place in your area. Some of the most important skills to possess include cutting, rigging, and fitting metal components, drafting design plans and standards, and testing and inspecting finished projects. Some wet-welders also train extensively in underwater videography and still photography to document the progress of important projects. Qualifications for underwater welders can vary not only from company to company, but from one project to the next.
A: Take and pass a preliminary dive physical. Become a certified commercial diver. Attend an underwater welding school. Apply for a dive tender position to continue your training on the job. Continue improving your skills to advance in your field.

Q: The USB port is located on the top of the controller below the triangle shaped light bar. The USB ports are next to the disk reader on the front of the console inside the slot. It's the button with the PlayStation logo located in the center of the controller between the two joysticks. This will pair the controller with the PS4. Once the controller is paired, you can turn on the PS4 by pressing the PS button on the controller.
A: Connect a USB cord to the controller. Connect the USB cord to the PS4. Press the "PS" button.

Q: Fill your sink or a bucket with warm (not hot) water and a small amount of mild dishwashing soap. Too much soap can leave a cloudy film, so only use a little bit. Swirl or agitate the water to mix the solution thoroughly. Line the bottom of the sink or bucket with a rubber mat, soft cloth, or even paper towels to prevent damage to your crystal. Do not use hot water to clean crystal as this can cause it to break. You'll want to do one piece at a time to prevent the items from clanking together, which could cause chipping or breakage. If needed, allow your crystal to soak for a few minutes. If your item is too big to fit in the sink or bucket, or cannot be fully submerged, such as a lamp or chandelier, dampen a soft cloth or sponge in the solution and use it to carefully wipe down the item. Use warm (not hot or cold), running water to rinse away any residue from the crystal. Don't rinse with cold water as the sudden temperature change can cause the crystal to crack. You may want to wear gloves to ensure you aren't putting fingerprints on your clean crystal. For those larger items, use a clean, wet cloth or sponge to wipe down the item and remove any lingering soap. You could also rinse your crystal in a bucket or bowl of distilled water, as this will reduce the amount of water-spots left behind. Rub the toothpaste around with a cloth, sponge, or even just your finger. Keep rubbing the toothpaste around on the crystal until you have removed the mineral deposits. Then, rinse the toothpaste off of the crystal. Be careful not to press too hard! If your crystal is cloudy from stuck on mineral deposits or other types of residue, then you might also need to cover it in a paste made from vinegar and salt. Pour about 1 tsp (3g) of salt into a small bowl and add just enough vinegar to form a paste. Spread the paste over the crystal, and leave it on the crystal for 10 minutes. Then, rinse the paste off when the time is up. For even more stubborn residue, put about 1/2 of a cup (120 g) of baking soda into the crystal and then pour 1 cup (240 mL) of vinegar over it. The foaming action will help to clean the crystal and remove the residue. Rinse the crystal with water after the baking soda and vinegar stop foaming. Gently wipe each item down with a lint-free cloth. This will remove any water spots and give your crystal a beautiful shine. Again, it is a good idea to wear gloves to prevent smudging your clean crystal.
A:
Create a solution with warm water and mild dish soap. Submerge your crystal in the solution. Rinse thoroughly. Apply a bit of toothpaste to remove mineral deposits on the crystal. Cover crystal in a mixture of vinegar and salt to remove deposits. Dry your crystal.
