Introduction
This manual provides essential instructions for the safe and effective use of UPTATSUPPLY Poseidon Tattoo Cartridge Needles, Model 0254 (1229 RM). These needles are designed for professional tattoo artists and are compatible with most cartridge tattoo machines and grips. Please read this manual thoroughly before use to ensure proper handling and application.

Safety Information
- Sterilization: Each cartridge is sterilized by EO Gas and individually blister-packed. Do not use if the packaging is compromised or opened.
- Single Use: These needles are for single use only. Dispose of used cartridges properly in a sharps container after each procedure.
- Professional Use: This product is intended for use by trained and certified tattoo professionals only.
- Storage: Store cartridges in a cool, dry place away from direct sunlight and moisture.
- Inspection: Before use, visually inspect each cartridge for any damage or defects. Do not use damaged cartridges.

Setup
- Prepare Workstation: Ensure your workstation is clean, sterile, and organized according to professional tattooing standards.
- Select Needle: Choose the appropriate UPTATSUPPLY Poseidon cartridge needle size (e.g., 1229 RM) for your intended tattoo work.
- Unpack Cartridge: Carefully open the individual blister packaging without touching the needle tip.
- Insert into Machine: Gently push the cartridge into the compatible tattoo machine or grip until it clicks securely into place. Ensure the cartridge is fully seated and stable.
- Check Stability: Verify that the needle is stable and does not wobble. The internal membrane prevents ink backflow and ensures needle stability.


Operating Instructions
These large size tattoo cartridge needles (e.g., 1229 RM) are particularly effective for filling large areas, shading, and creating bold lines. Their design facilitates efficient ink flow and consistent pigment saturation.
- Adjust Machine Settings: Set your tattoo machine's voltage and stroke length according to your preference and the specific requirements of the tattoo design and skin type. For large magnum needles, a slightly slower machine speed or longer stroke may be beneficial for optimal ink saturation.
- Ink Application: Dip the needle cartridge into your sterile tattoo ink cap. The design of the cartridge ensures good ink absorption and flow.
- Tattooing Technique: Apply the needle to the skin with consistent pressure and movement. The wide profile and sharp, surgical stainless steel needles are designed for high working efficiency, making them suitable for covering significant areas quickly and smoothly.
- Observe Ink Flow: Monitor the ink flow and adjust your technique or machine settings as needed to achieve desired saturation and prevent skin trauma.

Maintenance and Disposal
- Post-Use: Immediately after completing a tattoo session, carefully remove the used cartridge from the machine.
- Disposal: Dispose of the used needle cartridge in an approved sharps container. Do not attempt to clean or reuse cartridges.
- Machine Cleaning: Clean and sterilize your tattoo machine and grip according to the manufacturer's instructions after each use.
Troubleshooting
If you encounter issues during use, consider the following:
- Uneven Ink Saturation:
- Ensure the needle cartridge is fully seated in the machine.
- Check machine voltage and adjust as necessary.
- Verify consistent hand speed and pressure during tattooing.
- Inspect the needle tip for any visible damage before use.
- Needle Wobble:
- Confirm the cartridge is correctly inserted and locked into the machine.
- Ensure the machine's needle bar or drive bar is properly aligned with the cartridge.
- Machine Stops Working (during use with these needles):
- This is unlikely to be caused by the needle cartridge itself unless it is severely damaged and jamming the machine.
- Check your machine's power supply and connections.
- Test with a different, known-good cartridge or needle to isolate the issue to the machine or power supply.
