A device and method of commutation control for an isolated boost converter provides a unique commutation logic to limit voltage spikes by utilizing switches on the secondary side to minimize a mismatch between current in the inductor and current in the leakage inductance of the transformer when commutation takes places. The wand comprises an elongated, hollow tube having upper and lower ends with first and second water supply conduits being positioned adjacent the exterior surface of the tube. By one approach, this arm couples to the base andor the housing in a manner that permits an end user to adjust a position of the housing with respect to the base without requiring any hand tools.
