As soon as each hoses are related to the torch, it’s important to double-check for any potential leaks. Apply a cleaning soap answer or a leak detection spray to all connection factors and joints. If bubbles seem, it signifies a leak. Tighten the connections and repeat the leak verify till no bubbles are noticed.
### Step 7: Guaranteeing Correct Gasoline Move
Open the oxygen and acetylene valves on the regulators barely to provoke fuel move. Test if the fuel is flowing easily via the hoses by igniting the torch. If the flame is regular and constant, it signifies a correct fuel move. If the flame is inconsistent or erratic, regulate the regulators to acquire the proper fuel move charges.
Lighting the Torch
Step 1: Test the Gear
Earlier than lighting the torch, guarantee you will have all the required gear, together with a torch physique, acetylene and oxygen hoses, regulators, and a striker. Examine the gear for any harm or leaks.
Step 2: Join the Hoses
Join the acetylene hose to the acetylene regulator and the oxygen hose to the oxygen regulator. Tighten the connections securely utilizing a wrench.
Step 3: Open the Acetylene Valve
Slowly open the acetylene valve on the regulator, permitting the fuel to move into the torch physique. Modify the valve till a slight hiss is heard, indicating that the acetylene is flowing.
Step 4: Gentle the Striker
Ignite the striker, which is a small flint-based lighter, by clicking the button. Maintain the flame close to the torch tip.
Step 5: Open the Oxygen Valve
Slowly open the oxygen valve on the regulator, permitting the oxygen to combine with the acetylene. Modify the valve till a secure flame is established.
Step 6: Modify the Flame
Use the valves on the regulators to regulate the flame to the specified dimension and form. A impartial flame, with equal quantities of acetylene and oxygen, is appropriate for many functions.
Step 7: Troubleshooting
If the torch doesn’t gentle or the flame is unstable, verify the next:
| Downside | Trigger | Answer |
|---|---|---|
| No fuel move | Leaking hose, clogged orifice, or empty tank | Tighten connections, clear orifice, change tank |
| Flame too small | Low oxygen stress | Enhance oxygen stress |
