Abstract
A wheel protection system for moving a hose or cable on a working surface away from the wheels of a movable device, such as a portable welder. The wheel protection system includes a separate wheel guard positioned to at least partially surround each wheel of the movable device. Each wheel guard is mounted by a resilient mounting structure that allows the wheel guard to deflect upward upon contacting an irregularity on the working surface. Each wheel guard is independently mounted such that the device can be used on an irregular surface.
