Apparatus and methods for thermally processing a workpiece include directing a plasma arc to the workpiece and using a dielectric shield or dielectric coating to protect a forward portion (e.g., a torch head) of a plasma arc torch. The dielectric shield or dielectric coating covers a nozzle disposed within the torch head and protects the nozzle from the effects of slag and double arcing. The shield also improves operator visibility due to the spatial relationship between the dielectric shield and the nozzle.

The cooling system of a skid-steer loader provides for heat exchangers, e.g. liquid, oil coolers, mounted in the upper portion of an engine compartment and in direct communication with a forced air flow. Circulating air is drawn into the engine compartment from the rear, is carried over the engine and is blown out through the heat exchangers to cool the liquid within the heat exchangers. The housing of a centrifugal fan is rigidly coupled to the engine block and the fan is also directly coupled to the engine flywheel. This allows for closer tolerances between the fan and its housing which results in higher efficiency because this dual coupling to the engine inhibits differential vibration between the fan and the housing. Interconnection between the heat exchangers and fan housing is via a flexible bellows and an air diffuser.
