Welding is becoming really popular in the United States, considering its a high paying job. There are many types of welding out there, but one of the most difficult type is oxygen-acetylene welding. This kind of welding takes great training and concentration to become a natural at it,

There is an abundance of caution while welding. Such as wanting the right psi shown on the fuel and oxygen regulators. Or having enough oxygen and gas to have a neutral flame. I will explain how to set up the gas and fuel in order to lighting the torch. And i will also explain the proper techniques on how to be the best you can be.
To get started you will need your safety glasses, welding helmet, and welding gloves. You will now turn the oxygen cylinder valve enough to where it spins freely. Now you will turn the Acetylene cylinder valve open about a 4th of a turn. You will then turn the regulator valves enough to reach 7 to 10 psi. If you have two torches and two people welding then put the regulator at no more than 20 psi. Make sure the torch tip isn’t clogged up.

Turn the torch acetylene valve an 8th of an inch. Take the flint striker and strike in front of the tip. The torch will catch a flame. If the acetylene is to low there will be black smoke. Raise the acetylene until the black smoke stops immediately. Turn the torch oxygen valve until the feather of the flame is right in front of the torch tip.
To start your weld you need to have Carbon Steel wire. have that in the opposite hand of the torch. Hold the feather of the flame on the specified spot where you will start your weld. Wait for a bright orange pull to start, once it starts put the carbon steel wire an 8th of an inch above the liquid pool. The wire will start to melt and flow into the pool. keep the torch moving in the direction of where you want you weld. slowly follow it with the wire. To get the best weld make small circles with the torch. you should have a ripple effect too it if its done correctly. Once your done turn the torch acetylene valve off first then the oxygen.
