The Orb of Fusing in PoE is sort of like that Swiss Army knife you would expect to find in a pocket. Use it for re-rolling links between sockets on weapons or armor. However, the color and number of sockets don't change. This item is in high demand and trades at around 3 chaos orbs to 1 orb of fusing. Save them for crafting top-tier gear towards the endgame during mapping.
