Abstract
An improved wet abrasive blast machine with remote control rinse cycle enables a pilot operating the apparatus to control remote switching between blast and rinse cycles directly, for example from a nozzle of a blast hose or from a panel. A first and second hydraulic circuit and a pneumatic circuit are controllable via communication with a control circuit which is operable remotely to direct a configurable pilot signal between various valve states. In a preferred embodiment, the control circuit is powered pneumatically via a branch circuit fed from the pneumatic circuit. Switching between to configurations is effected by directing an air pilot signal between airflows interior to a series of valves. In an alternate embodiment switching airflows between configurations is effected electrically.
