An Enzyme Welder is a small hand tool used to cut through metal or weld two pieces of metal together using protein enzymes to catalyze a chemical reaction rather than using heat or brute force. Depending on the enzymes used, they can also be used to cut or meld plastics, ceramics, or even living flesh. As such, it is an essential part of any tool kit, and one is built into the manipulator arms of every RP-12 Repair Pod.
