Abstract: A kit for fusing piping includes a plurality of couplings, each coupling having a susceptor layer concentric with a weld zone. A control unit provides a current to a wand with a handle for gripping by a user. The handle has opposing jaws mounted on the distal end, each jaw including an arcuate conductor such that the arcuate conductors form a circular inner diameter when the jaws make contact. A lever system couples to the distal end for opening and closing the jaws. The lever system includes a spring for selectively biasing the lever system in a latched position with jaws closed and an open position with the jaws open. Each coupling is sized such that the jaws will only close about the weld zone. The arcuate conductors create a fuse zone about the susceptor layer and the spring is outside the fuse zone.
