- Max cut size 1“ (at 65A) -

Members need to supply their own plasma consumables - these are available for purchase at the front desk.

**Do NOT cut stainless steel on this machine** - hot metal operations on stainless steel can produce hexavalent chromium, which is highly carcinogenic.

Top up the water in the water table if there's >5mm of open space to the top of the slats

Roll the trash bin by the plasma over to the sink, fill it, return to CNC plasma, and slowly pour water in the center of the water table using the included bucket.

Ensure a good nozzle and electrode are loaded in the torch head

Disconnect the THC wire and unscrew the head

Verify the amperage rating of the nozzle (45A or 65A printed on the side)

Replace electrode and/or nozzle if the wear pattern is not symmetric

Screw down the head until it gently stops, then reattach THC wire

Turn on the Hypertherm and ensure its amperage setting matches the nozzle rating

Turn on the control box and use Mach3 to move the head free of your work area

Load your material and attach the ground clamp nearby

Draw the curtain behind you to protect other members from arc flash

Create/edit an existing tool for Material Type & Thickness by referencing the [Hypertherm Torch Operator Manual](https://www.google.com/url?q=https://drive.google.com/file/d/1cVR8hSIFpbJe9-G18MAgyezId-ENfhoz/view?usp%3Dsharing&sa=D&source=editors&ust=1676742581134637&usg=AOvVaw1IO5f0tY43Aa8oXN4MrMF7 "https://www.google.com/url?q=https://drive.google.com/file/d/1cVR8hSIFpbJe9-G18MAgyezId-ENfhoz/view?usp%3Dsharing&sa=D&source=editors&ust=1676742581134637&usg=AOvVaw1IO5f0tY43Aa8oXN4MrMF7")l to your Material Type & Thickness:

Feed Rate

Pierce Delay

Pierce Height

Cut Height

Import your plasma .DXF file as “new part”

Select your part

Create new “Plasma Cut” Operation (Operation>Plasma Cut)

Select the layer that contains the vectors you want to cut

Choose Contour Method

Outside Offset is typical for jobs with a mix of closed/open profiles

Enter the feed rate based on your material type and thickness

Configure lead-in and lead-out settings and press OK

Verify that the cutting preview shows the appropriate direction & leads

To prevent the cutter from crashing into parts that flip up during operation, go to Options → Job Options and ensure the Rapid Clearance field is set to 3” or larger (a higher value takes longer to touch off when starting a cut, but is less likely to crash on already cut pieces)

Run the Post Processor to create your .TAP g-code file

Hit flashing red “Reset” button to clear Emergency Stop condition

If the button does not reset when clicked, check that E-Stops & Proximity Limit Switches are unlocked

Select “Reference All Home” (wait until all three axis lights are green)

Zero X, Y, and Z axis

Load your file (File>Load G-Code)

Jog the machine head to the left/front corner of the desired origin (arrow keys)

Before zeroing, make note of the coordinates so that, if you need to restart mid-cut, you’ll have the exact location to return to

If prefered, select ”MDI Alt 2” to manually jog to the nearest whole number for your desired origin

Zero X and Y on the left/front corner of the desired origin

Zero Z with torch approximately ¼” above the material surface (page up/down)

Trace the job location using jog/arrow keys to ensure your file fits where desired

Safety Check:

Identify nearest fire extinguisher

Ensure E-Stop is easily accessible

Put on appropriate eye protection

Select “Cycle Start” to begin cutting

Turn off the control box

Turn off the plasma cutter (Hypertherm)

Remove any remaining material from the table

Detach the ground clamp and store it clear of the water table

If using your own consumables, remove them from the nozzle and replace them with a spare from the workstation table.

If using one, **remember to take your flash drive with you!**
