Step 1. Build main table assembly using LH and RH side assy and 2 x centre beams.
Note:
Ensure white dots are at front when assembling.
Ensure ground is at, if need-be use shims to ensure table I level.
Ensure white dots at front
Fit 4 x Allen key bolts, nuts and washer at points show per each corner

Step 2. Fit main centre beam assy
Centre beam comes ed with rail & motor and torch holder & motor.
Locate each end bracket onto side rails ensuring torch holder is towards the front.
Fit 4 x Allen head bolts, nuts and washers - DO NOT TIGHTEN YET
You now need slowly bring centre beam forward so each side motor bracket touches the front
arms of frame.
Once both are touching now ghten the 4 x securing bolts -
This ensures table will be square.

Step 3. Fit cable support arm
Fit the cable support beam using the 2 long allen head bolts, buts and washers to the front le leg of main table.
Step 4. Fit table slats
Fit table slats as per picture above, ensure gloves are worn to avoid injury.
Note: Picture shows oponal water table and support beams ed.

Step 5. Fit torch to torch bracket on centre beam
Torch head comes with bracket ed as above
Fit torch bracket to mounng point on centre rail. Note: Do not overghten bolt B as this can cause restricon to electrode
movement - See below
Aer ng torch bracket to centre torch mounng - move the
centre electrode up and down, when pushed up and let go it
should move down quickly, if it is slow to move down, slacken
of the boom right bolt B on torch bracket unl it moves freely.

Step 6. Fit wiring to CNC Controller
CNC Control Box

Connect two wires from centre torch bracket to point A -it does not maer which way wires go as they are
not polarity dependant.
Connect two wires from safety stop buon on console to B -it does not maer which way wires go as they
are not polarity dependant. Note: Fit safety switch to console rst so wires go through hole in console.
Connect the 4 x motor plugs into sockets which are all colour coded - locate by using alignment lugs on plug and socket, then
turn the end ring E on plug to screw it into socket.
Connect parallel cable into socket C and connect 240v mains cable into D - DO NOT PLUG INTO MAINS SUPPLY YET

Step 7. Console Setup
Put PC and CNC control box on rear stand of console.
Fit monitor to console using mounng points and bolts supplied.
Fit CNC control box onto console using points and bolts supplied A.
Fit Stop switch to console using points and bolts supplied B.
Fit Parallel port cable from CNC console to parallel port on PC.
Plug keyboard, mouse and monitor into PC unit

The CNC table, console and PC assembly is now complete, all you need to do now is connect the CNC interface cable A to
rear of R-Tech Plasma Cuer, then setup the Plasma Cuer as per the owners manual instrucons supplied with P50HF.
Now refer to guides on how to use the CNC soware to start cung.
