WAZER Pro High Pressure Performance Check

Prevention is better than cure. When the high pressure system performance decreases, the cut result is directly affected. This article introduces some quick checks which jointly reflect the performance and status of the high pressure system, so any potential problem can be quickly detected and addressed.

Required Tools

Flashlight (recommended)

Spare Parts needed

Contact WAZER Support for any replacement parts

Procedure

Pressure Check

Remove any cut materials from the cut bed

Go to “setup and maintenance” > “maintenance” > “nozzle purge” or “tank cleaning” or “water level set up”

Follow the UI screen prompt to engage the high pressure system

While water is being ejected from the nozzle, take a look at the high pressure gauge located on the front panel of WAZER Pro

Check if the needle stays in the green zone of the gauge.

If the needle is below the green zone, take a picture and contact WAZER support.

If the needle is constantly in the yellow zone, take a picture and contact WAZER support

If the needle goes up to the red zone, turn off WAZER Pro immediately and contact WAZER support.

Orifice Flow Check

After checking the operation pressure, we need to check the orifice condition.

Sometimes the pressure may be staying in the green zone, while the orifice is damaged and cannot deliver good cutting.

Remove the abrasive hose from the side of the cutting head

Move the cutting head to the upmost position, lock it in place, and unscrew the nozzle guard.

Pull down the nozzle guard. The guard will not move out side to side as the nozzle length keeps it in place.

Pull down the plastic collar and nozzle tip into the guard. This will give you enough space in order to move the nozzle tip and guard out of the way.

With the nozzle tip out of the way, we can view the stream of high pressure water directly leaving the orifice.

go to Setup & Maintenance > Maintenance > Nozzle Purge.

Observe the orifice stream leaving the nozzle assembly.

The stream must be focused and concentrated.
The flow rate must be maintained during the testing phase, any pulsating or throbbing flow indicates a pump issue or input water flow restriction.
An exaggerated spread could be caused by a clog in the nozzle or broken orifice.
Uneven Distribution of Stream could be due to a broken orifice

Suction Check

Open abrasive drawer and remove the Abrasive Hose from the Abrasive Catcher.

Navigate to Setup & Maintenance > Maintenance > Nozzle Purge and start the routine while keeping your water on. Make sure to keep the abrasive hose plugged into the side of the nozzle.

While the Nozzle Purge is running, place your finger over the end of the abrasive hose.

You should feel a suction strong enough to stick the hose onto your finger.

If you do not feel any suction, it could be down to:

Clog or restriction in the abrasive hose
Pressure instability
The nozzle tip is not fully seated into the nozzle assembly after the orifice check.

Leak Check

After all the checks listed above, open the bottom left and bottom right stress skin panels, left middle panel

Trace the water hose from filter canister, to the high pressure pump, to exterior high pressure hose fitting.

Check for any leaks or pulled water near any fittings.

Then move the right side of the WAZER Pro, check any leaks near the filter cartridge and damper valve.

Move on to the banjo fitting. Conduct another nozzle purge, pay attention to the Banjo Washers. Make sure no stream of mist coming out anywhere around the banjo fittings.

Next Time

Paying close attention to the operation pressure during a cut is a good habit. The needle of the high pressure gauge is a good indicator of high pressure system performance. Contact WAZER support if you see any abnormal behavior of the needle.
