The MG (Rotary Magazine) is a highly durable magazine with capacity of up to 10-12 electrodes, depending on the diameter. Each electrode position has a singular O-Ring to securely hold the caps.

The Magazine is by default pokayoked to prevents incorrect attachment of the magazines from the upper and lower tips. A locking switch is used to securely fasten the magazine to the tip changer. A standard proximity sensor pairs with the unit to relay a signal that detects when the cartridge is empty or detached. The magazines for the upper and lower electrodes can be easily distinguished with a color marking on the upper side of the magazine.
