Overview

We have a WAZER. Here is a quick overview:

The WAZER is a table-top waterjet cutter. Waterjet cutting uses a mixture of high-pressure water and an abrasive, it has the ability to cut through many materials. The WAZER is limited only by the repository of materials that are currently available on their online Material Library. In order to set up a cut, a 2D design must be created in an outside program (Solidworks, Illustrator, Fusion360, Inkscape, AutoCad, Onshape, etc) and then take a DXF or SVG file and upload it to WAM which is the slicing software. WAM is browser based and its use is outlined in the WAM Software Guide. The WAZER uses a relatively constant stream of abrasive, so we charge $3.25/min of runtime. The runtime only includes time that the actual water jet is running, and does not include stuff like set up and alignment. WAM will tell you how long the waterjet will actually need to run for eaach cut.

Anatomy

The WAZER has two main components: the main unit and the pump box. The pump box is the smaller enclosure on the right and is responsible for pressurizing the water that comes out of the building’s water system. The main unit is the larger of the two and contains the cut bed and control panel. The main unit is the only part of the WAZER that needs to be interacted with, the pump is fully controlled by the WAZER and should not be messed with.

The main unit has several parts to be aware of:

Wazer Central Parts

The Abrasive Hopper holds the garnet sand that is mixed with the pressurized water at the cutting head.

The Enclosure holds the cutting bed, water, used abrasive and material.

The Control Panel is the main interface through which the Wazer is operated.

SD Card Slot

The SD Card Slot is where cut files are uploaded to the Wazer.

The Power Switch is located underneath on the right side.

Operation

The WAZER will not turn on unless there is a certain amount of water in the tank (about 2/3rds) but should not be attempted to run unless the water level is within ¼ inches of the top of the cut bed.

In order to run, the water supply from the building’s plumbing MUST be turned on otherwise the pump box will be severely damaged.

Detailed Procedure

Step One: Check water levels

Step Two: Turn on water supply

Specific Water Supply Reference

Step Three: Prepare abrasive system

IMPORTANT: At no point should any abrasive material be physically added to the inside of the main tank, abrasive needs to be completely dry when it is mixed with the high pressure stream of water inside the cutting head.

The buckets with the metal handles need to be carefully removed and emptied before each new cut.

Step Four: Plug the pump in

IMPORTANT: Be sure to remove the Abrasive Hose End from the Cutting Head and move it somewhere that it is unlikely to get wet.

Step Seven: Refer to the WAZER Software SOP to ensure that your cut is ready to go.

Step Eight: Insert SD Card, from the Main Menu go to “Select Cut File” and navigate to your file.

Step Nine: Lift the Nozzle and Home the WAZER

Step Ten: Fasten Material

Step Eleven: Nozzle Height

Step Twelve: Check Cut Extents

Step Thirteen: Ready to Cut

IMPORTANT: DO NOT, UNDER ANY CIRCUMSTANCES OPEN THE COVER OF THE WAZER WHILE IT IS SET TO CUT.

If the cut stops for any reason or throws up an error, get a manager before trying to move on and fix the problem yourself, even if the error seems minor.

Step Fourteen: Shutdown and Clean-up
