Here is a feature not found on other rotary machines in regards to using needle cartridges. I have been using cartridges exclusively for about 3 years now... and with some of the rotaries I was using... the return spring/pressure on the cartridge would null the give/hit and I couldnt run my machines at lower voltages. I am sure anyone else using cartridges, now what I mean. So I developed a special feature to counter this issue.

When using the the popular needle cartridges with the Venom3DP Skorpion, you can wrap a standard tattooing rubber band around the lower ears, to compensate for the return spring installed in the cartridge. This allows the Venom3DP Skorpion to run at lower voltages, while still providing a soft or medium hit when using needle cartridges. A Venom3DP Skorpion exclusive innovation!
