4. Configuració

Before beginning the flaring process, ensure your tubing is properly prepared:

1. Cut Tubing: Use a tubing cutter to make a clean, square cut on the end of the tube.
2. Desbarbar: Carefully deburr both the inside and outside edges of the cut tubing to remove any sharp edges or burrs. This is crucial for a proper, leak-free flare.
3. Neteja: Ensure the tubing is clean and free of debris.

5. Instruccions de funcionament

Follow these steps to create a bubble flare:

1. Select Flaring Bar Hole: Open the flaring bar and select the hole that matches the diameter of your tubing (e.g., 4.75mm, 6mm, 8mm, or 10mm).
2. Inserir tub: Insert the prepared tubing into the selected hole.
3. Adjust Tubing Projection: Position the tubing so that it extends slightly above the surface of the flaring bar. The exact projection may vary slightly depending on the desired flare height; typically, it should be just enough to allow the adapter to form the flare without bottoming out.
4. Tubs segurs: Close and tighten the clamps on the flaring bar to firmly hold the tubing in place. Ensure the tubing does not slip during the flaring process.
5. Selecciona l'adaptador: Choose the correct adapter for the tubing size you are flaring.
6. Position Yoke: Place the yoke assembly over the flaring bar, aligning the cone of the yoke with the center of the tubing and the adapter.
7. Form Flare: Slowly turn the handle of the yoke clockwise. This will press the adapter into the tubing, gradually forming the bubble flare. Continue turning until you feel firm resistance, indicating the flare is fully formed. Do not overtighten.
8. Alliberament i inspecció: Turn the yoke handle counter-clockwise to retract the cone. Loosen the flaring bar clamps and carefully remove the tubing. Inspect the newly formed bubble flare for uniformity, smoothness, and absence of cracks or imperfections.

6. Manteniment

Proper maintenance ensures the longevity and performance of your flaring set:

• Neteja: After each use, wipe down all components with a clean, dry cloth to remove any metal shavings, dirt, or oil.
• Lubricació: Periodically apply a light coat of machine oil to the threads of the yoke's screw mechanism to ensure smooth operation.
• Emmagatzematge: Always store the flaring set in its TFM428PB storage case to protect it from dust, moisture, and physical damage.
• Inspecció: Regularly inspect the flaring cone and adapters for wear, nicks, or damage. Damaged components can lead to improper flares and should be replaced.

7. Solució De Problemes

If you encounter issues during flaring, consider the following:

• Uneven Flare: Ensure the tubing is cut squarely and deburred properly. Check that the tubing is clamped securely and not slipping. Verify the adapter is correctly centered.
• Cracked Flare: This can be caused by insufficient deburring, using too much force, or cold tubing. Ensure tubing is at room temperature.
• Leaking Flare: Often due to an improperly formed flare, burrs, or dirt. Re-cut and re-flare the tubing, ensuring cleanliness and proper technique.
• Difficulty Turning Yoke Handle: Lubricate the yoke's screw threads. Ensure the tubing is not over-projecting from the flaring bar.
