Extra springs! These are steel springs with a passivation process done to prevent corrosion.
Use Heavy Duty only if you are having trouble stabilizing Regular springs. Heavy Duty is primarily for use with cartridges with very light spring tension, and regular springs for everything else.
WARNING: Using Heavy Duty Springs with cartridges with strong spring tension can overload the motor and reduce its lifespan! Use only if necessary.
Carson Hill of Neuma Device has developed his fourth-generation tattoo machine, Neuma 4, after a few years of research with a particular interest in creating a ‘pen-style’ rotary tattoo machine that would place a strong emphasis on addressing the inherent limitations of traditional rotary mechanisms. The result is a multi-cam rotary mechanism that can line as quickly and effectively as a coil machine; plus shade, blend, and pack color efficiently, predictably, and reliably.
Artists’ first impressions are very positive, and feel they are outstanding liners as well as very efficient with all styles of tattooing. After a bit of experimentation with the various cams Neuma offers, artists quickly realize the high degree of utility the system offers and grow to love them even more for their versatility.
There are a number of Neuma 4 configurations that can appeal to artists of all types with all sorts of preferences. From grip size to weight, varying strike force and stroke length, there is certainly a configuration for anyone who uses Neuma 4 to suit any preference. Let your Neuma 4 conform to your personal preferences, rather than having to conform your tattooing style and approach to the performance of your machine.
