Step 1: First Things First
As you can see in the picture, we store the oxy-acetylene rig with the bottles facing forward. We do this so that you can make sure that they are securely fastened to the cart. If they are not securely fastened, tighten the wing nut.
Step 2: Get the Kit Out of the Welding Cage
Get the welding cage opened by a staff member. Get out the OXY box. Inside the box there should be a cutting torch, several welding torches, torch cleaning supplies, a striker and a welding pressures chart.
Step 3: Choose Your Torch Kind and Size
Are you welding or cutting? What is the thickness of your material?
Use the red card to help you decide on an appropriate sized cutting or welding tip.
Step 4: Check for Your O-rings
There should be two o-rings on the base of your welding/cutting tip. If you are cutting, the o-rings are easy to see. If you are welding, the o-rings may be more difficult to see.
Step 5: Install Torch Top to the Torch Body
Remove the dust cap and screw the torch top onto the torch body.
Step 6: Preparing to Open the Tanks
Make sure that both torch valves are turned off. Then make sure both the regulators are off. You know the regulator is off when the adjusting knob spins freely.
Step 7: Opening the Tanks and Setting the Pressure
Follow the steps provided in the images. Open oxygen all the way, open acetylene 1/2 turn.
Step 8: Start Cutting or Welding!
If you need help getting the torch lit and adjusted to a neutral flame, find a staff member and they will be happy to assist you.
