My CNC Plasma Table's Water Pan | Fabrication & Install
HTML-код
- Опубликовано: 25 янв 2022
- Following the building of my CNC plasma cutting table, the final thing was the fabrication and installation of the water pan. This video shows how we fabricated and installed the water pan, which is a vital part of the plasma cutting table.
The main reason for the water pan is to trap the harmful fumes, sparks and smoke that are generated by the plasma cutting process.
Reducing the harmful fumes from the air around the plasma cutting table, makes for a safer working environment, which is a good thing.
The water pan is 1500 x 1500 x 100mm and is made from 3mm mild steel. The slats are 50 x 3mm flat bar laid on their edge and they're curved to prevent excessive damage during the cutting process, should a cut ran parallel to and on top of a slat.
The water pan holds approximately 225 litres of water and it's my intention to use a plasma cutting additive to reduce bacteria, rust and corrosion.
A shout out to Luke at Swags Engineering, who cut and folded the water pan, as well as cutting the slots and folding the slat frames.
Luke is located at Unit 11, 21 Hurrell Way in Rockingham. His email address is: swagsengineering@gmail.com

Great build series!! I love the use of simple materials to build the frame and the X and Y axis rails. I’m looking forward to building my own table soon and I’m looking for any and all ideas and your series pretty much ticked all the boxes. Thanks for the videos. 😃👍🏻👍🏻
Thanks for your kind words, Stephen. I now offer plans and a parts list for the table I built, so if you're interested in purchasing the plans, feel free to email me at rmhyde58@gmail.com
Excellent!! I will do that. 😃 Thank you!!
Good one
Thankyou.
Great job Rusty! Thanks for the movie.
Cheers Frank. The water pan also made cleaning the dross off the underside of the pieces, much easier, which is a nice bonus.
I like the idea of having the three way ground on there as well.
"Here's one I prepared earlier" ĺove it mate, awesome job mate.
I added the magnetic base earth clamp and used it today....much easier to use than the standard earth clamp that ends up half submerged in the water.
Thanks Jim. I had the table cranked up today, cutting out metal garden chooks!!
Super job!!!!
Thanks Michal...glad you liked the video.
Rusty, thanks. for your video. I am just putting together my own DIY plasma table and noticed the CAD software your using is the same one I will be using as well. Thanks again. Great Video.
Thanks for your comments, Geoffery and I'm glad you enjoyed the videos. The MyPlasm software is easy to set up and use, which is a real bonus.
Great job....👍
Thanks Vince.
I really like the design of your plasma table. Did you build it yourself? I am thinking of building one.
Hi Ron, yes I built the table myself. If you 're looking for some inspiration for your own build, check out the build series videos on my channel. If you have any questions about my build, feel free to get in touch, ok.
Hey Russel...always nice to see yours video
Is your water pan made stainless steel or from mild steel.
Thanks.
Hey Michel, nice to hear from you. The water pan is made from 3mm mild steel, as are the slats and slat frames. They've all gone a bit rusty, but nothing noticeable at present, after 2 years of use.
Great looking machine! If the slats are perpendicular to the open end of the machine, it should be easier to slide material on/off the table.
I'm looking to install a teflon strip across the top edge of the front rail, to help with sliding a sheet on, but I see what you mean about having the slats running up and back, instead of across the machine, as they are now.

"Do a google for "Ball Transfer bearing"
For the long term you can use a engine hoist with a 4 way spread bar to load heavier sheets.
Keep on keepin' on!
The other option I'm looking at is to install a gantry trolley and chain block, running from the front to the back of the shed, so I can unload a sheet of material from the trailer and load it onto the table.
@@RustysMetalCutSignsDesigns That's my plan as well when I add onto the shop for the plasma room. Currently I use a stinger on the fork lift.
Hi Rusty,
Where did you get your water bed cut and folded
I want same size water bed but struggling to find place in WA that can cut 1.7M wide ( size of bed plus sides to be folded up)
Hi Milos, Luke from Swags Engineering in Rockingham fabricated the water bed for me...here's his details:

I hope he can help you.
Hey Russell! I have been looking around at wiring the electronics up for these tables and some of the instructions call for grounding the table directly to the earth, not back through the power source. Is that how you have yours?
Hi Frank, I've connected all the earths and cable screens from the field devices, back to a common grounding point inside the electronics cabinet. I've tied that common ground point to the earth point from the incoming AC mains supply.
As for the table, the frame, water pan and plasma cutter's ground clamp, all go back to a common point on the frame.
The electronics cabinet and the table frame ARE NOT connected together.
I was thinking of tying the frame's common grounding point to an earth stake in the ground, but was advised against that, because the earth return path for the plasma torch should be back to the plasma cutter...ie. the electrical circuit wants to go back to the origin, which is the plasma cutter itself. So that's how mine is connected.
I'm about to make a mobile 'console' that will contain my laptop, a screen and the electronics cabinet. It won't be able to move very far because there's not a lot of slack in the cables from all the field devices coming back to the electronics cabinet.
I know there's lots of tables with the electronics cabinet mounted on the side, and that's where mine was going to be mounted, but I'd rather keep the 2 items electrically isolated from each other if I can....so that's how I'm going to do it. Hope this helps. If you have any more questions, you can always email me at rmhyde58@gmail.com
Thanks for the reply! That pretty much goes along with what I have read about grounding the shielding and field components back to the common in the electronics box. I think the difference between your machine and others machine is the triple work lead lug. Most would just run one lead back to the plasma cutter as normal. I wonder if the triple lug needs to be isolated from the main frame . Then a cable from the main frame directly to the earth. I am not in any way saying that your way is incorrect. I’ll check with a local electrician for the code on that when the time comes. Thanks Rusty!
The reason for the triple work lead plate is to make connecting the various ground leads easier than having them all attached to a single bolt. This way, I've got the ground lead from the cutter on one bolt, the earth strap from the water table to the ground plate on one bolt and the work clamp and work magnetic clamp on another bolt. All the grounding is to one common location on the table, and this is connected to the ground connection on the cutter, making a solid return path. So far, it's working as planned and I'm not having any issues with EMI with the electronics cabinet.
Could you tell me why you end up 100mm deep waterpan? What differend it make if it is 70mm? I make my plasmatable body ready and i am wondering how deep i should do the waterpan.
Hi Markus. I made the water pan 100mm deep because I'd seen other tables with water pans this depth. The deeper they are, the less often you have to clean them out, I suppose.
100mm is also the height of my Y axis frame rails, so I wanted to keep the top of the water pan and slats level with the top of frame.
I suppose you can make the water pan any depth you like, but I wanted as much water under the torch as possible, to make sure I captured as much of the fumes, smoke and sparks that the plasma cutting process creates. I hope this helps.
Hi rusty where abouts did you get the linear rails from ?
Hi Daniel, I bought pretty much all of the equipment online....,mostly from ebay. The linear rails I used were HGR20 guide rails with HGH20CA bearing blocks. Mine are 1500mm long but they are available in a range of sizes to suit your application. Hope this helps. If you need any more info about the build, feel free to email me at rmhyde58@gmail.com
FYI, I noticed in previous videos and the last segment of this one, the audio is very harsh when you are in front of table facing the camera. I don't know if it is a different microphone or simply the different orientation, but it is quite jarring and unpleasant when it switches... Again, great videos, keep up the good work and have a great day!
Thanks for your comments. The audio is something that I'm working on but thanks for bringing this to my attention.
Hey survivethewalkingdead, I've been doing some testing of the audio and found that if I place the lapel mic further away from my mouth, the audio sounds more 'normal' and not clipping. Appreciate you bringing this to my attention.
Hey Russel are your tips lasting long???? my unimig 30 tips are not lasting that long and im only cutting 3mm mild steel
G'day Ian, I've probably not cut that much yet, in order to wear out tips. I have replaced 1 tip and electrode (the original ones that were in the hand torch when I got the cutter), not long after I started cutting on the table, but since then I'm still on the 0.9mm tip and I've cut some 1.6mm mild steel and some 3mm aluminium.
I've got more 1.6mm mild steel to cut so before I start, I was going to check the condition of the tip and electrode....which I suspect the tip might be on the way out.
What state you in.....I'm in WA.
@@RustysMetalCutSignsDesigns ahhh ok. I'm from nsw. I have used plasma's for over 10 year's being a metal fabricator and this plasma just seems crap to me. Only way to get nice cut's is slow the speed down. Be interesting to see what you're machine does when cutting 3 or 5mm sheet 🤔
I've got some small items to cut out of 5mm mild steel so I'll have to change the tip, anyway. I'll let you know what settings I use.
Hey Ian, what cut chart are you using for setting up your table to cut various thicknesses of material. If you send me an email (rmhyde58@gmail.com) I'll forward you a cut chart I got from the Langmuir Systems forum relating to the Razor Cut 45.....I know you're using a 30 but it's got settings up to 30 Amps for thin material.
Can you send me a list of all the components that I need please that would be so much appreciated
You're doing such a great great job
If you send me an email to rmhyde58@gmail.com I will send you the parts list.
Whats the purpose of the fluid? It splashes water everywhere and on the computer.
The water bath is there to trap the fumes, sparks and smoke that are produced from the plasma cutting process. Breathing in these fumes isn't good for your health.
The water also aids in cooling the metal, especially when cutting thin gauge.
