4. Installation and Setup
The Reboot MB15 Ceramic Nozzles are designed for quick and easy replacement on compatible MIG welding torches.
4.1 Preparing Your Torch
- Ensure your welding machine is turned off and disconnected from the power source.
- Allow the torch to cool completely if it has been recently used.
- Carefully remove the old nozzle by twisting and pulling it off the torch head.
- Inspect the contact tip and gas nozzle holder for any wear or damage. Replace if necessary.
4.2 Attaching the Nozzle
- Align the new ceramic nozzle with the torch head.
- Gently push and twist the nozzle onto the torch until it is securely seated. No special tools are required for this process.
- Ensure the nozzle is firmly attached and does not wobble.

5. Operating Instructions
These ceramic nozzles are specifically designed for gasless flux core MIG welding. Their design allows for better visibility of the weld puddle, which can improve welding accuracy.
5.1 General Usage
- Always wear appropriate personal protective equipment (PPE), including a welding helmet, gloves, and protective clothing.
- Ensure proper ventilation in your work area.
- Set your MIG welder to the appropriate settings for flux core welding, considering wire diameter and material thickness.
- The ceramic material's transparency allows for a clearer view of the arc and weld pool, aiding in precise bead placement.
5.2 Flux Core Welding Tips
- Maintain a consistent stick-out (distance from the contact tip to the workpiece) as recommended by your flux core wire manufacturer.
- Use a drag technique (pulling the torch) for flux core welding to achieve better penetration and bead appearance.
- The ceramic nozzle's smooth surface helps reduce spatter adhesion, making cleanup easier.
6. Maintenance
Proper maintenance extends the life of your ceramic nozzles and ensures consistent welding performance.
6.1 Cleaning
- Regularly inspect the nozzle for spatter buildup.
- Due to the ceramic material, spatter tends to adhere less and can often be easily removed by gently tapping or spinning it off with a gloved hand.
- Avoid using harsh abrasive tools that could scratch or damage the ceramic surface.
- Ensure the nozzle's opening remains clear for proper wire feed and arc stability.
6.2 Storage
- Store unused nozzles in their original packaging or a protective container to prevent chipping or damage.
- Keep nozzles in a dry environment, away from excessive heat or cold.
7. Troubleshooting
Below are common issues and their potential solutions related to the ceramic nozzles.
| Problem | Possible Cause | Solution |
|---|---|---|
| Nozzle chips or breaks easily | Impact or rough handling; inherent fragility of ceramic material. | Handle nozzles with care. Store them in a protected manner to prevent impacts. |
| Nozzle does not fit torch | Incompatibility with torch model. | Ensure your torch is an AK15, MB15, or MB14 model. These nozzles are designed for specific torch types. |
| Excessive spatter buildup | Incorrect welding parameters (voltage, wire speed); improper technique. | Adjust welding parameters. Ensure proper stick-out and torch angle. Clean nozzle regularly. |
| Poor arc stability | Damaged or worn contact tip; debris inside nozzle. | Inspect and replace contact tip if necessary. Clean any debris from inside the nozzle. |
8. Safety Information
WARNING: Welding can be hazardous. Always follow general welding safety guidelines in addition to these product-specific instructions.
- Eye Protection: Always wear a welding helmet with the correct shade lens to protect your eyes from intense light and UV radiation.
- Body Protection: Wear flame-resistant clothing, welding gloves, and safety shoes to protect against burns and electric shock.
- Ventilation: Ensure adequate ventilation to remove welding fumes, which can be harmful if inhaled.
- Fire Prevention: Keep flammable materials away from the welding area. Have a fire extinguisher readily available.
- Electrical Safety: Ensure your welding machine is properly grounded. Never weld in wet conditions.
- Hot Surfaces: Nozzles and torch components will become extremely hot during welding. Allow them to cool before handling or performing maintenance.
