De ce am nevoie de un arc diferit pentru cartușe?

Cartușele au masă, rezistență și mecanism de conectare la needle bar diferite față de acele tradiționale. Arcul STD (nr. 78) este calibrat pentru ace standard, iar arcul nr. 79 este calibrat pentru cartușe. Cu arcul potrivit obții forța de retur corectă; cu cel greșit, retracția poate fi prea agresivă sau insuficientă.

Pot folosi arcul STD (nr. 78) cu cartușe?

Tehnic mașina va funcționa, dar nu la performanța optimă. Arcul STD poate da o forță de retur inadecvată pentru ansamblul cu cartuș — fie prea puternică, fie insuficientă. De aceea Ink Machines a proiectat arcul nr. 79 special pentru cartușe; pentru calitatea lucrării și siguranța clientului, folosește arcul corect.

Cum se schimbă de la arcul STD la cel pentru cartușe?

Demontează componentele necesare accesului la camera pistonului, scoate arcul nr. 78, montează arcul nr. 79 în aceeași poziție, îndepărtează arcul nr. 24 „Stay up”, reasamblează și re-ajustează spring stop screw-ul (nr. 77) pentru noua preîncărcare. Apoi testează pe piele artificială. Procesul invers se aplică la revenirea la ace standard.

Cum îl curăț și pot să-l sterilizez?

Curăță-l cu alcool izopropilic 70% sau soluții dezinfectante de nivel medical. Autoclavarea este posibilă, dar poate accelera oboseala materialului. Indiferent de metodă, clătește și usucă complet piesa înainte de a o remonta.

Funcționează cu mașina Dragonfly sau cu orice mașină?

Nota produsului menționează Dragonfly și Stingray pentru această configurație, dar camerele pistonului pot diferi între modele, așa că verifică întotdeauna compatibilitatea specifică pe tatuat.ro înainte de a presupune interschimbabilitatea. Nu monta piesa „la ghici” dacă nu ești sigur de model.

Câte bucăți primesc într-o comandă?

Produsul se livrează la bucată (1 buc). Dacă vrei rezerve, comandă mai multe — este recomandat să ai 2-3 arcuri în trusă pentru continuitate.

Guide & full description

Complete guide: Inkmachines nr. 79 - Inner piston spring for cartridges - 1pcs

The Ink Machines Spring No. 79 is a replacement part for InkMachines rotary machines: the internal piston spring, specially calibrated for use with cartridge needles. It is intended for artists who use a cartridge system on a compatible InkMachines machine (e.g., Stingray) and need the correct needle bar return force. Unlike the STD version (part no. 78, for standard needles), this spring has its elastic rate adjusted for the mass and resistance of the cartridge assembly, providing complete and controlled needle retraction. Sold individually (1 piece).

How to use

Ensure your InkMachines machine is set up for the cartridge system and have the No. 79 spring ready, plus a clean work surface for small parts.
Disassemble the necessary components to access the piston chamber, following your machine's disassembly order.
Remove the STD spring (part no. 78) if installed, from its position.
Insert the No. 79 spring (inner piston spring for cartridges) into the same position.
Remove the No. 24 'Stay up' spring — according to the manufacturer's note, it must be removed for Dragonfly and Stingray machines to function with this setup.
Reassemble and readjust the spring stop screw (part no. 77), as the different elastic rate requires a different preload.
Use a power supply with kickstart or built-in start-up cable, as indicated in the product note.
Always test on artificial skin, with the cartridge mounted, before working on a client.

Tips from us

After every spring change, readjust the spring stop screw (no. 77) — the return force is adjusted from here.
Do not mix setups: the STD spring (no. 78) is for standard needles, the no. 79 spring is for cartridges. Using the wrong one results in either overly aggressive or incomplete retraction.
Check the spring tension monthly and replace it at the first signs of loss of elasticity (slow, incomplete, or inconsistent retraction).
Keep 2-3 spare springs in your kit to avoid being stuck in the middle of a session.
Since this is a small part, work over a tray or towel to prevent losing it during disassembly.

Warning: Clean the spring with 70% isopropyl alcohol or medical-grade disinfectant solutions; autoclaving is possible but may accelerate material fatigue. Rinse and dry the part completely before reassembly. Using the wrong spring for cartridges can lead to inadequate needle retraction — either too aggressive (traumatic impact on the skin) or insufficient (risk of needle stick) — so always test the setup on artificial skin before a client.

Frequently asked questions

Why do I need a different spring for cartridges?▾

Cartridges have different mass, resistance, and connection mechanism to the needle bar compared to traditional needles. The STD spring (no. 78) is calibrated for standard needles, while the no. 79 spring is calibrated for cartridges. With the right spring you get the correct return force; with the wrong one, retraction may be too aggressive or insufficient.

Can I use the STD spring (no. 78) with cartridges?▾

Technically the machine will work, but not at optimal performance. The STD spring may provide an inadequate return force for the cartridge assembly — either too strong or too weak. That's why Ink Machines designed the no. 79 spring specifically for cartridges; for work quality and client safety, use the correct spring.

How do I change from the STD spring to the cartridge spring?▾

Disassemble the components needed to access the piston chamber, remove the no. 78 spring, install the no. 79 spring in the same position, remove the no. 24 'Stay up' spring, reassemble, and readjust the spring stop screw (no. 77) for the new preload. Then test on artificial skin. Reverse the process when switching back to standard needles.

How do I clean and can I sterilize it?▾

Clean it with 70% isopropyl alcohol or medical-grade disinfectant solutions. Autoclaving is possible but may accelerate material fatigue. Regardless of method, rinse and dry the part completely before reassembling.

Does it work with the Dragonfly machine or any machine?▾

The product note mentions Dragonfly and Stingray for this setup, but piston chambers may differ between models, so always check specific compatibility on tatuat.ro before assuming interchangeability. Do not install the part 'by guess' if you are not sure of the model.

How many pieces do I receive in an order?▾

The product is delivered individually (1 piece). If you want spares, order multiple — it is recommended to keep 2-3 springs in your kit for continuity.

Product description

Inkmachines nr. 79 - Inner piston spring for cartridges This spring must be used in combination with cartridge needles to be able to control the give properly. NOTE: The No. 24 - Stay up spring must be removed for the Dragonfly and the Stingray machines to work with this setup. Powersupply with built in kickstart or start up cable must also be used. The Inner Piston Spring for Cartridges InkMachines (part no. 79) is the original internal piston spring for InkMachines machines specifically configured for use with cartridges (cartridge needles), the elastic component with elastic rate calibrated differently from the STD version (part no. 78) to provide optimal return force in cartridge configuration. Tattoo cartridges have different mechanical characteristics than traditional needles: different assembly mass, different connection mechanism to the needle bar (click-in vs. tube), and different resistances to alternating movement. The inner piston spring for cartridges compensates for these differences through an adjusted elastic rate — providing complete and controlled needle bar retraction specific to the mass and resistance of the cartridge assembly. If you use the STD spring (part no. 78) with cartridges, the return force may be inadequate: too strong (needle returns too aggressively, traumatizing skin) or insufficient (incomplete retraction, needle stick risk). The dedicated cartridge spring (part no. 79) eliminates these risks. Manufactured from high-quality spring steel, heat-treated for elastic consistency across tens of thousands of cycles, the inner piston spring for cartridges provides the consistency needed for professional work with cartridge systems. Monthly checking and replacement at the first signs of tension loss is recommended. The spring works together with the spring stop screw (part no. 77) allowing additional fine-tuning of return force.
