It depends on which gun you have:
The pink one is called Advanced Tape Glider.
The red ATG (and the yellow one which uses wider adhesive) is the Adhesive Transfer Gun.
Although they look the same, they are built differently. The pink one is the "crafter's" version of the red one, which is why the pink one is cheaper. The red ATG is made for industrial use. The gears in the red gun are built differently, to withstand gumming up from the adhesive.
