Don't try this at home: Wiring a plasma cutter for CNC | Hypertherm Powermax 30 XP

Today we're rewiring a Hypertherm Powermax 30 XP plasma cutter for use on a CNC plasma table. Don't do this. It's dangerous. It's also easy, and it works great.

Great video as always. I may never make a CNC plasma cutter, but I definitely enjoyed seeing you making one and explaining how to (not..) do the same

[@stevensmart8868]

Great safety notice at the beginning. And awesome video.

[@AtomicSaunders]

This video is wonderful. I would really like to thank you for taking the time to make it. It clearly, and concisely explains how to wire up a RAW voltage connection for langmuir system plasma table. I was having trouble for days trying to get my system working. I spent hours combing over message boards, and help pages that were helpful but led m down rabbit holes without solving the issue.. This video helped me to retrace my stems, taught me what to check for, what each system does, how to tap into them, even how to use a voltometer to check for continuity. After and during watching this I was able to track down my system problems and immediately start cutting.... Thank you so much for making this. You made my day.

[@jerrydemas2020]

If you want a DIY air dryer. Use a whole house water filter housing filled with Fresh Step Crystal kitty litter. Put it in the air in line of the air compressor. The crystals won't change color when getting saturated, but you can put a small hydrometer in the housing so you can see the gauges Jerry in Pa..

I’m excited to see your experience with this machine, I have been in the market for something like this

As usual another great video James. I have my Crossfire over a year now and love it. Using the PrimeWeld CUT60 successfully. I'm running Mach3 (I don't like being "locked-in" to a manufacturer's control system) on my shop-floor Dell Optiplex 780 PC. Built my own CNC controller and integrated my own Torch Height Control (THC) using the RobotT3T and built my own floating head Z-axis. I 3D print my machine torch holders in PLA (they last about 1-year). Great machine the Langmuir Crossfire, and they have a great and very informative and active forum.

My handheld unit I already (Eastwood VersaCut 40) have IS high frequency unfortunately. Given your level of experience with F360 and CNC I expect your setting up of the post processing should be pretty quickly accomplished.... let's see some cuts, James!

I looked at one of these tables 2 years ago. I was at a welding class (with someone that is big on youtube) He had the table and reviewed it. He had nothing good to say about it, but his standards are probably far above what my needs are. You make a good point, chances are, anything that doesn't meet your needs, you are plenty capable of correcting. I'm excited to see what you do, maybe it will come back on my list again! BTW, I would go with the Hypertherm 45, why? 15 more numbers of course!

[@visionforge1254]

Just wanted to point out you probably should have a separate air dryer, either a large desiccant dryer or refrigerated air dryer as you will still get moisture in the lines. I've destroyed dozens of plasma torch heads and rusted many many parts during sand blasting even with an inline filter at the end of the air line, an air filter mounted on the plasma cutter and another filter at the compressor. Dedicated air dryers make a night and day difference.

[@joeldriver381]

Woohoo! As of the posting of this he was not dead.

[@cjtroutt8092]

Hi James In regards to plasma cutting you might want to invest in line desecant air dryer filter it will prolonged your Consumables and results will be alot better in the long run. I built my cnc plasma table. I am going to get in the future a refrigerator dryer. This will help with moisture in the air.

[@bobuk5722]

Hi James, I suggest sheathing the red and black HV leads carrying the torch height info. Over here they would be double layer insulated and I think it would be wise to guard against mechanical damage. Spiral wrap? BobUK,

[@Clough42]

Not a terrible idea.

[@yngndrw.]

I believe the wire used in multimeter leads is double insulated as part of the CAT III rating.

Another outstanding tutorial and dialog. As you rightfully explain, no mater what it is; or how simple it seems; SAFETY, SAFETY, SAFETY 1ST !!!!! Check, double check and check again.....a body part or your life aren't worth the chance.

I suggest that you rig up some ventilation... Even with a water table, CNC plasma tables can smoke you out quick... Don't ask how I know that :)

how does the 30 Air work with the X fire? enough air that it keeps up?

[@erikmoe2361]

@@matthewhagans4372 I'm still trying to get the settings right. One thing I've learned about the Air is you have to adjust the pierce delay to give it enough time to ramp up the compressor

[@trialnterror]

I have a cutmaster 42 by victor. Doesn’t have a Cnc port so I need to first tap into mine to fire like you mention. Then I have a thc like you mentioned that I need to hook up! From what I hear is if you use a thc and a floating head attachment that’s the best way that way you would not need a ohmic sensor. Also I’m up in the air if I should use millrights supplied board that runs UGS or one of the following 1. Myplasma 2. Masso 3. Centroid acorn (which I currently run on my Bridgeport but they are currently in beta on the plasma. If they release it soon this may be my go to board)

They should provide some 3-way Wago connectors with their kit instead of the crimps.

[@jesusisalive3227]

[@H34...]

Phew that was close, I did this at "home" a few years ago. Luckily it was on the older powermax 30, not the XP, so it's ok right? Cool to finally see someone else do this, and their approach. Mine didn't have one of those voltage dividers since the cnc was shop built, but it wasn't too hard to build and I shoved the circuit for it into the case so that it didn't bring the high voltage outside the case other than torch/work clamp... Then I got lazy with the height probe circuit ("ohmic" or contact probe) and brought it outside the case anyway because space inside the plasma case was getting tight (it's almost like they don't want you shoving extra circuitry in there?) and I'd already installed and wired up a 6 pin plug and would need a 10/12 pins at least to shove the probe circuit inside the case, and I couldn't be bothered. I'm glad I did this way since the probe circuit tends to blow a chip every now and then, and having it easily accessible outside the case ended up being very useful. The probe circuit for me went in with the rest of the control electronics Side note for anyone following along at home the powermax 30 (not sure about the XP) actually has two relatively beefy leads in the torch. I believe the second one is for the pilot arc, and if memory serves you can only connect one of them to your voltage divider, the other will have a pretty much constant voltage with regards to the work clamp regardless of torch height.

[@cncdavenz]

Its good to have a new toy in the shop :-)

[@ocAToccd]

"Don't do it... It's easy but don't do it" 🤣🤣 Clean install 👍👍 I actually have the 45XP for manual cuts but when I bought it I intended to put it on a table (not yet had the time in almost 2 years... But it's on its way 😍) so I took the CNC package with the mech torch and the preinstalled communication module and added the manual torch... In Belgium it was cheaper than buying the "manual package" and add the mech torch and the module (and you then have to install it yourself...) Good machine by the way 👍 What I found odd on the 30xp is that the filter is inside the box... On the 45xp it is recessed but accessible from the outside (with tiny hands... But still...) And it needs cleaning every now and then... Are you "allowed" to open the box to clean the filter?

[@OmeMachining]

Great project 👍😃 a cnc cutter, laser or plasma do make allot of things sooooo much easier 😃

[@swolebro]

RIP to your beautifully clean workshop. If you can put an exhaust hood over the machine, in addition to the water table, I'd strongly recommend it. You should also build an electromagnetic vise with some MOTs for holding pieces while you knock off the dross - it's a massive timesaver.

[@scottwillis5434]

Any suggestions on what a good exhaust hood would be like? CFM, style so it won't be too much in the way, how high should it be...

[@davidhaywood9071]

Several things: First great video and clear explanation of what you are doing I love watching your videos. Second, do you have a connection with Langmuir Systems that benefits you when I purchase one of their systems? Third, I like the computer setup you have and I must have missed your video where you discussed the details of the one you’re using. Would you be able to provide info on the details of the Asus you are using?

Thanks for the video i followed the video to the tee but with one expected because i dont have that part and my question is if i dont have that part which the high frequency device that you connect to the electro negative and electro positive ( ground ) I tried it but could not get any conductivity .

[@yngndrw.]

It's great to see that these cheaper Hypertherm units can be used for CNC. My only complaint about the THC kit that you used is that the voltage divider is external - I would have liked to see only low voltage signals leaving the Hypertherm unit's case. (Aside from the torch, of course!)

[@somebodyelse6673]

Who do we know that could re-home all the guts into a new, custom made case? Heh, James could do that so well that a factory tech would be wondering when that model was made...

[@Clough42]

I'd probably go the other direction. The circuit inside the THC is very simple. It would be pretty straightforward to make a version that fits inside the case. Hmm...

[@frigzy3748]

My line of thoughts was maybe figure out the schematic of the HV regulator inside the unit and tap into the torch voltage before it becomes HV? Say, input of an op-amp as oppose to the output.

[@tjnak]

Hi James, why not wire in a switch on the front for the fire control manual vs CNC? that way the ghost in the pc won't be tempted to toast you when using it manually :)

[@scottwillis5434]

Good idea, one issue being 'oops, I forgot'. One thought is putting another switch on the CNC mount: if the head is not in place, the CNC cannot fire it.

[@AmateurRedneckWorkshop]

Great video. My 2 cents worth by all means use it every time with water. Otherwise it will deposit metal powder all over your shop. I have been told that if you put some borax in the water it will not rust so bad. Oh and like some of the others suggest you really do need an air dryer. I can assure you that water will get to the torch otherwise.

[@Clough42]

I have a box of 20 Mule Team sitting on my kitchen counter as I write this.

[@senselessinductor7921]

The Powermax 45 I have has an integral CPC port and has a voltage divider on the main board wired to the CPC. (I'm still wary of non divided current going towards my systems control box on my CNC, so I would have still used a divider circuit) *I also made my own CPC cable, because they're using off the shelf parts you can get at digikey... The problem with Hypertherm machine torch operation from the CPC, is that the wiring of the torch to the connector is different, and is required. (They built a failsafe wire that isn't in a hand torch, and is wired to different pins. So either you pay their high priced fee for a machine torch (about a grand) Or you hack your hand torch, and make it much harder to use as just a hand torch. I opted to use a lathe to make an acetal housing for a custom connector (the brass fitting is the real challenge bit, and the DIN pin alignment and indexing SUCKS) Then I could purchase a machine torch head from eBay, and then proceed to make my own lead for it. (It even offers the ability to use better and more robust materials for the lead...) --- Instead of their high priced machine torch, I opted to buy a lathe, and make my own connector... Glad we can all hack our stuff and make it do what we need it to.

[@court2379]

While you were at it you should have rerouted the power switch to the front panel, instead of the idiotic place on the back panel... Never understood why they put them there. For when you are using it manually you could have installed a safety CNC disable firing switch so you know it cannot be set off. Thanks for showing this. It is close to what I would be likely to setup. On your power, it doesn't matter if you only have 100A, you can install much more output than available because they are not likely to all be running at the same time. So the only real limitation would be the wire size to the plug.

[@tidesign7625]

Just a thought, $2000 to $4000 might be a good investment to upgrade the 100 amp panel to 200 amps. Consider Square D as a panel. It's only 2 cents worth.

[@Eggsr2bcrushed]

Depends on if the utility company is willing to change the neccesary equipment, even if it comes at cost to James.

[@scottwillis5434]

Does that include the utility upsizing the pole transformer and running bigger feeder wires?

[@tidesign7625]

It’s been my experience that the incoming conductors (wires) do not need to be upsized. All that is needed is maybe a meter change and a new 200 amp main breaker panel be installed be a qualified electrician, and of course a permit is required.

[@mabmachine]

I think you are running THC 1.1 and 1.2 is current. You've probably already figured this out but the post file needs to match the THC control version.

Do things in this order: 1. Unplug, remove cover 2. Use voltmeter rated for 400+VDC, with good insulation on the leads, to verify that lethal voltages are not present 3. Touch anything inside Someone I know once touched the inside of a camera strobe that had been off for two weeks. His scream was clearly audible at the other end of the house. Perhaps battery-powered camera strobes are a special case; storage capacitors should have bleeder resistors -- and 'should' is not the same as 'do, and Purchasing didn't get crappy ones that failed, and the assembler put them in place, and the terminals didn't corrode, and they still work'.

I knew LESS THAN NOTHING about electronics. But a few of his videos and explanations of circuitry… It got me tinkering… The next thing I knew......three years later..... I had my own lab doing component level board repair for industrial clients. And I specialize in test equipment repair/calibration & metrology. I’m just as busy and happy as I ever was doing full-time woodwork.....And I’ve learned an incredible amount of things… And have skills I never thought I was capable of! you KZbin folks and especially creators like yourself… have an insane amount of influence on your audience! Sorry to ramble… I know I’ve left this comment on a few of your other videos but I would just really love it if you could make a few more circuit board and troubleshooting related videos. The few electronics videos you’ve shared with us have been awesome! especially the video last year where you were troubleshooting the DMX amplifier board. That was a very insightful and information packed video! It would be awesome if you could do a few other videos showing quick troubleshooting of circuit boards. Nothing fancy.... just some broken power supply or other board/circuit commonly found in industrial and consumer level products.… show us how to troubleshoot and find common faults. I constantly have clients and friends ask me to teach them… But I’m not good at explaining things. I try to encourage them to go online and watch a few videos. The only videos I’m aware of on KZbin that give a good and quick general overview of troubleshooting… Are on the “diode gone wild” channel. He has a few videos troubleshooting power supplies… And within 30 minutes pretty much explains how to find and test every common problem. Other than his videos… There is a HUGE VOID and quick and easy troubleshooting videos on KZbin. Someone would have to watch 100 hours of content just to grasp the basic ideas of how to find and test issues. I love my test equipment and professional gear like they are my children… But 90% of the boards that come through my shop… Could be quickly and easily tested and fixed with less than $100 of tools. Including a decent but cheap multimeter, a $30 in circuit ESR tester, and a $25 CHEAPO Oscilloscope. There are some really nice tools and pieces of kit that can be had extremely cheaply. One needs to recognize their limits… But its the golden age of decent and cheap test equipment and tooling.

The solution wasn’t proper wire/cables, wiring practices/management, grounding, and adequate power sources.... it was to remove all accessories and just make more money. Snake oil. Cheep. Shameful.

Just cause the house is 100 amp only is no sign you cant put a 50 amp in the garage just a little common sense and don't run everything at the same time Stop playing with sheet metal toys and go 45 XP with a Duramax machine torch. CPC connector is ready to rock.

I know you will but please cover all of your tools ways! Yuck, plasma smoke is gross.

[@billstanley4819]

It’s not only gross but unless I’m wrong it is black iron oxide…which is an abrasive. Very bad for machine ways. I keep my plasma cutter in a building that is separate from where my machine tools are located. I also have a 36 inch exhaust fan above it.

[@kylebracht]

@@billstanley4819 that's what I was referring to. Its equivalent to grinder dust and emory dust in my opinion

[@Clough42]

Good tip. I'll probably end up running it at the other end of the shop. Not a lot of light over there at the moment.

[@kylebracht]

@@Clough42 probably best. Maybe wipe your ways before using your machines for good measure. Even a large fan blowing out the door might help. But yes, from experience, that dust goes evvverywhere

[@celiturbo]

@@Clough42 An hour of running a 40amp plasma in a 3 car garage left more dust/grit on everything than a day of sanding bondo/primer or all the over spray from painting a whole car. If you have a clean shop, you do not want to run it in there without taking serious measures to manage the literal fallout first. I roll mine out to the driveway winter or not now, I dont have neighbors though, and still have to clean the dust up or it rust stains the driveway. Stuff Made Here, did a downdraft setup that seemed to exhaust it out well.

[@new-kids-on-the-block]

Everything you do nice and then you do a bad job with those f****** connectors😏 you should have used a wago or something

[@ma-is8vh]

Where did you get the wiring to modify it??
