Initial • Ensure all valves (on the torch and both cylinders) are closed before beginning. • Check that oxygen and acetylene cylinders are properly secured to prevent tipping.

Connecting Regulators and Hoses1. Attach the oxygen regulator to the large oxygen cylinder (green). 2. Attach the acetylene regulator to the smaller acetylene cylinder (red). 3. Ensure the regulators are tightly connected but avoid over-tightening.

Opening Cylinders 1. Open the Oxygen Cylinder: Turn the valve counterclockwise to fully open. 2. Open the Acetylene Cylinder: o Open the valve no more than a quarter-turn. This allows quick closure if necessary.

Set Oxygen Pressure:Open the Main oxygen valve on the torch slightly to allow gas to flow, then adjust the oxygen regulator on the tank to reach approximately 20 PSI. Test pressure by momentarily pressing the torch trigger, adjusting if needed.

Set Acetylene Pressure: on the Torch, open the main acetylene valve slightly, then adjust the acetylene regulator to around 5-10 PSI.Test and adjust as necessary.

Checking for Leaks • Apply a soapy solution to connections and hoses to detect leaks. • Watch for any bubbles, indicating a leak. Tighten connections if needed or replace defective parts.
