How to light an oxy acetylene torch
Lighting an oxy-acetylene torch is both an art and a science, a sort of dance with flame that, when mastered, opens up a world of possibilities in welding and metalworking. I remember the first time I lit one; the hiss of the gases and the flicker of the light created a mesmerizing moment. This wasn’t just about heating metal—it was about controlling fire, harnessing energy in a precise manner. In this article, I’ll guide you through the steps to safely and effectively light an oxy-acetylene torch, along with the essential safety tips I’ve learned along the way.
Overview of Oxy Acetylene Torch Use
Oxy-acetylene torches are widely used for welding, cutting, and brazing metals. The combination of oxygen and acetylene creates an incredibly high-temperature flame. Understanding the torch’s basics allows for better control and efficiency when working on projects, from small repairs to large metal fabrications.
Steps to Light the Torch
1. Inspect the Cylinders
Before anything else, I always inspect the gas cylinders. This involves checking for any signs of damage, rust, or leaks. A simple visual check can save a lot of trouble later on.
2. Check the Torch for Damage
Next, I check the torch itself for any signs of wear and tear. Any damage here can lead to dangerous leaks or improper flame control.
3. Install Reverse Flow Check Valves
I ensure that reverse flow check valves are installed. These little devices help prevent backflow of gas, keeping my workspace safe and reducing the risk of accidents.
4. Ensure Proper Ventilation
Ventilation is crucial. I always make sure that my workspace is well-ventilated to avoid dangerous gas buildup. Opening a window or using exhaust fans can make a big difference.
5. Open the Oxygen Cylinder Slowly
When it’s time to get started, I open the oxygen cylinder slowly. This helps to prevent any sudden pressure surges that could lead to accidents.
6. Attach Regulator to the Oxygen Cylinder
After that, I attach the regulator to the oxygen cylinder. This step is critical; the regulator controls the gas flow and helps manage the pressure.
7. Attach Regulator to the Acetylene Cylinder
Likewise, I proceed to attach the regulator to the acetylene cylinder, ensuring that I secure it correctly to avoid leaks.
8. Connect and Secure Hoses
Next, I connect the hoses to the torch. This step requires careful attention to ensure everything is attached tightly and correctly.
9. Pressurize the System
With everything connected, I slowly pressurize the system by opening both cylinder valves. It always feels like a thrilling moment as I hear the soft hiss of the gases.
10. Conduct a Leak Test
I perform a leak test at this point. Using soapy water, I check for bubbles around the connections—no bubbles means no leaks, which is always a relief!
11. Adjust the Regulators
Once I’m confident everything is secure, I adjust the regulators to set the desired pressure for both gases.
12. Lighting the Flame
Finally, it’s the moment I’ve been waiting for! I ignite the acetylene first, allowing it to form a small flame, then I gradually open the oxygen until the flame turns blue and stabilizes. It’s a beautiful moment when I control the intensity of the flame.
Safety Tips
Important Safety Precautions
Safety comes first, so I never skip using proper personal protective equipment—like goggles, gloves, and long sleeves—whenever I work with an oxy-acetylene torch. I also maintain a clear workspace free of flammable materials to avoid any fire hazards.
Common Mistakes to Avoid
Errors in Setup
One common pitfall I’ve noticed is neglecting to check for leaks or skipping the inspection of equipment. These seemingly small oversights can lead to dangerous situations.
Lighting Errors
Another mistake is improperly lighting the torch. Always ignite acetylene before oxygen; otherwise, you could create backfire situations that can be dangerous.
FAQs
What to Do in Case of a Flame Out?
If the flame goes out unexpectedly, I immediately turn off the acetylene, then the oxygen, and wait a few moments before relighting to avoid any flashback issues.
How Do I Adjust the Flame?
To adjust the flame, I tweak the oxygen and acetylene regulators until I achieve a controlled, steady flame that suits my welding needs.
Conclusion
Recap of Key Points
In conclusion, lighting an oxy-acetylene torch is a systematic process that requires attention to detail. From inspecting cylinders to adjusting the flame, following these steps not only ensures safety but also enhances efficiency in welding tasks.

Recommended Tools
As a bonus, I’ve found that investing in high-quality welding gloves, goggles, and a fire extinguisher are essential tools that support safe and effective use of an oxy-acetylene torch.
How to start an oxy-acetylene torch?
Starting an oxy-acetylene torch begins with checking and securely connecting the equipment, ensuring sufficient ventilation, and then proceeding to gradually ignite the acetylene followed by the oxygen.
How do you light an acetylene torch?
To light an acetylene torch, you open the acetylene valve slightly, ignite it, then adjust the oxygen valve to achieve a properly balanced flame.
Do you light oxygen or acetylene first?
I always light the acetylene first, as this minimizes the risk of flashbacks and dangerous flare-ups.
When lighting an oxy-acetylene torch, what is turned on first and turned off first?
When lighting, I turn on the acetylene first and then the oxygen; conversely, I turn off the oxygen first and then the acetylene when finishing.
