- Acetylene hoses
- Strain regulators
- Hose connectors
### Step 2: Making ready Your Oxygen Hose
Start by choosing an oxygen hose that’s suitable with the torch and the regulator. Reduce the hose to the specified size utilizing a pointy knife, taking care to not minimize too brief. On one finish of the hose, connect a strain regulator that’s rated for oxygen use. Ensure to connect the regulator tightly to the hose to forestall leaks.
### Step 3: Making ready Your Acetylene Hose
Just like the oxygen hose, choose and minimize an acetylene hose that’s suitable with the torch and regulator. Join a strain regulator particularly designed for acetylene on one finish of the hose. As soon as once more, guarantee a safe connection to forestall gasoline leaks.
### Step 4: Connecting the Oxygen Hose
Find the oxygen inlet on the torch and join the ready oxygen hose to it. Use a hose connector to safe the connection and tighten it firmly to forestall leakage. Be certain that the oxygen hose is labeled or color-coded to keep away from confusion with the acetylene hose.
### Step 5: Connecting the Acetylene Hose
Establish the acetylene inlet on the torch and join the ready acetylene hose to it. Safe the reference to a hose connector and tighten it correctly to forestall gasoline leaks. It’s essential to obviously label or color-code the acetylene hose for simple identification throughout use.
### Step 6: Double-Checking for Leaks
As soon as each hoses are linked 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 test till no bubbles are noticed.
### Step 7: Making certain Correct Gasoline Circulate
Open the oxygen and acetylene valves on the regulators barely to provoke gasoline circulate. Examine if the gasoline is flowing easily via the hoses by igniting the torch. If the flame is regular and constant, it signifies a correct gasoline circulate. If the flame is inconsistent or erratic, regulate the regulators to acquire the proper gasoline circulate charges.
Lighting the Torch
Step 1: Examine the Tools
Earlier than lighting the torch, guarantee you could have all the required tools, together with a torch physique, acetylene and oxygen hoses, regulators, and a striker. Examine the tools for any harm or leaks.

Step 3: Open the Acetylene Valve
Slowly open the acetylene valve on the regulator, permitting the gasoline to circulate into the torch physique. Alter the valve till a slight hiss is heard, indicating that the acetylene is flowing.
Step 4: Mild 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. Alter the valve till a secure flame is established.
Step 6: Alter 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 mild or the flame is unstable, test the next:
| Downside | Trigger | Resolution |
|---|---|---|
| No gasoline circulate | Leaking hose, clogged orifice, or empty tank | Tighten connections, clear orifice, change tank |
| Flame too small | Low oxygen strain | Enhance oxygen strain |
