Water Exiting Under Abrasive Hopper
Water may spill out of the fitting that is located at the bottom of the Abrasive Hopper. This is refereed to as a Backflow in the water jet industry.
Check: was the Pump Box on when it was supposed to be Cutting? You should clearly hear the sound of the Pump Box turning on when you start a Cut.
Root Cause: If not, the Pump Box is not receiving power or signal to turn on.
Corrective Action: Make sure to connect the Pump Box to an AC power source with the Pump Box Power Cable. Also, ensure the Signal Cable coming from WAZER is plugged in. Before resuming, you must clean out the Abrasive Hopper and Abrasive Hose. Follow the instructions in Maintenance > Maintenance Procedures > Cleaning the Abrasive Hopper and Abrasive Hose.
Check: Did the Nozzle come in contact with the Material you were trying to cut? This can be checked by powering off WAZER and seeing if the Nozzle is rubbing against the Material.
Root Cause: If yes, crashing the Nozzle into the Material you are cutting and not maintaining the correct offset can result in a backflow.
Corrective Action: Identify why the Nozzle contacted the Material. Is it an incorrectly leveled Cut Bed? Was it a Pop-up? Was it Material deformation? Identify the reason for the failure and correct for it. Before resuming, you must clean out the Abrasive Hopper and Abrasive Hose. Follow the instructions in Maintenance > Maintenance Procedures > Cleaning the Abrasive Hopper and Abrasive Hose.
Check: Did the inlet water pressure dip during the cut? If you have a large water consuming appliance or even a utility sink on the same water line as your WAZER it can cause a dip in water pressure.
Root Cause: A a large water draw will dip the inlet pressure which is then reflected in the high pressure after the pump. While this isn’t a big deal most of the time if it happens at the wrong time, like a pierce, it can cause a backflow.
Corrective Action: Identify large water users on the same circuit and make sure they are off during a cut
