Lighting the Propane Torch
To safely light a propane torch, follow these detailed steps:
1. Check the Connections
Ensure that the propane tank is securely connected to the torch and that all hoses and valves are properly tightened. Loose connections can lead to leaks and dangerous situations.
2. Open the Propane Valve
Slowly open the valve on the propane tank to allow gas to flow into the torch. Do this gradually, as opening the valve too quickly can cause a sudden burst of gas and potential ignition problems.
3. Ignite the Torch
Using a spark igniter or lighter, position the flame near the tip of the torch nozzle. Simultaneously, press the trigger on the torch to release gas. When the gas ignites, adjust the flow rate to achieve the desired flame size.
4. Fine-Tune the Flame
To optimize the flame for the intended task, use the following guidelines:
| Purpose | Flame Characteristics |
|---|---|
| Brazing | Neutral flame, slightly oxidizing (excess oxygen) |
| Soldering | Neutral flame with a small, sharp inner cone |
| Heating | Oxidizing flame (more oxygen, less acetylene) |
| Cutting | Carburizing flame (more acetylene, less oxygen) |
Note: It’s important to experiment and adjust the flame settings based on the specific material and application.
Adjusting the Flame
To adjust the flame size, use the valve on the torch’s handle that lets the right amount of propane gas flows into the torch head. When you open the valve, more propane enters the torch head, making the flame taller. You can get a smaller flame by closing the valve.
Apart from adjusting the flame size, you can also regulate the type of flame produced. The two main types of flames are:
- Oxidizing Flame
- Reducing Flame
Oxidizing Flame
Oxidizing flames are produced when there is more oxygen than propane in the torch. These flames are hotter and produce a blue central cone. They are ideal for tasks like soldering, cutting metal, and brazing. Here’s how to adjust the torch for an oxidizing flame:
- Open the valve slightly to allow a small amount of propane to flow into the torch head.
- Open the oxygen valve fully.
- Ignite the torch and adjust the propane valve until you see a blue central cone in the flame.
Reducing Flame
Reducing flames are created when there is more propane than oxygen in the torch. These flames are cooler and produce a yellow central cone. They are ideal for tasks such as bending metal, annealing, and heat treating. To adjust the torch for a reducing flame:
- Open the propane valve slightly to allow a small amount of propane to flow into the torch head.
- Open the oxygen valve partially.
- Ignite the torch and adjust the oxygen valve until you see a yellow central cone in the flame.
| Flame Type | Description | Ideal for |
|---|---|---|
| Oxidizing Flame | Hotter, blue central cone | Soldering, cutting metal, brazing |
| Reducing Flame | Cooler, yellow central cone | Bending metal, annealing, heat treating |
