3. Operation
The Helios Rotary Pen is designed to work with any power supply that will accept a
standard jack connection. For best results, we recommend using a Critical brand power
supply. The Helios Rotary Pen operates at 5 - 10v DC. DO NOT operate it with more
than 10v - 10.5v DC, you will run the risk of burning out the motor.
4. Cartridges
The Helios Rotary Pen is compatible with most brands of needle cartridge. We highly
recommend using the Helios Rotary Pen with Helios Needle Cartridges for best results.
With the machine switched off, insert a cartridge into the Helios Rotary pen by pushing
the cartridge into the pen and then twisting it clockwise, to lock the cartridge into place.
Once you carefully make sure the cartridge is locked into its proper position, you may
begin the tattoo procedure.
