Wet abrasive blast machine with remote control rinse cycle

An improved wet abrasive blast machine with remote control rinse cycle enabling remote control of blasting operations between a rinse cycle and a blast cycle, said improved wet abrasive blast machine comprising:

• a first hydraulic circuit communicating waterflow to a blast pot, a slurry hose, and a blast hose;
• a second hydraulic circuit communicating waterflow to the blast hose to bypassing the blast pot and the slurry hose;
• a pneumatic circuit communicating outflow of air through the blast hose;
• and
• a control circuit comprising an air pilot signal directable to enable remote switching between the first and second hydraulic circuits and to cease operations of said first and second hydraulic circuits and operation of the pneumatic circuit without deactivating action of at least one pump pressurizing said first and second hydraulic circuits nor action of a compressor feeding air to the pneumatic circuit;
• wherein immediate cycling between a rinse cycle and a blast cycle is controllable remotely, and by a pilot operating said blast hose, to rapidly switch between blasting and rinsing operations when actively engaged in surface cleaning.
