Hello Larry. Many thanks for video!

Nice video with very good tips. Thanks!

BEEN Super Helpfull so glad you shared this video, Thanks

Great job sir ,thanks !

Thanks a lot. Very good video. I need your help. I have Chinese cnc with hypertherm powermax 65. Suddenly from yesterday no arc coming. I didn’t change anything except power and speed. Even no error on the display. Please Need you help. Thanks in advance.

thank you, nice work!!!

Hi. I saw your video, it's excellent. Thanks for the input. Right now I have problems with my THC, but I think it has to do with interconnection. since the voltage arc is not yet received by the THC. If it's not too much trouble, could you provide the connection scheme? I use a similar THC and a powermax hyphertherm 85, apart from a cnc controller of the same brand. thank you, I hope you read my message.

Doctor buenas noches,buen dato el que has dado ojala hubiera mas gente como tu,bueno soy de Peru y tengo algunos problemas con la coneccion de mi THC que compre, para empezar el controlador es el mismo solo que el inversor que tengo es del otro modelo,si pudieras dar algunos datos de como hiciste para conectar el inversor con tu maquina plasma,te lo agradeceria y la programacion de THC,de antemano te agradesco la tencion prestada.

Hey,thanks for the video but i got problem with my SH-HC30 that is the torch does not Automatic lifting up during the cutting

Thanks for shearing.

Hi Larry, thanks for the information and contribution, I have a similar problem, the plasma that I am using is Chinese from the BP brand and the CNC is also Chinese, the torch makes a point and the arc is lost, however it continues to send air, continuing to move. Please your help.

Hi larry, thank you for sharing this valuable info. I have the same problem i have start fire model XPTHC-16 virsion connected to hypertherm powermax ×125 the plasma machine most of the time stop in the begning of the cut or in the middle of the cut and i recive these two diffrent notificaton in the screen 1- ARC BK and sometimes ARC detect failure i tried to follow the same steps u do and i have found the bord for J1 and J2 but it is in diffrent situation J1 2 wires are connected to it one for work + and other is for Elector1 and J2 two wires connected to it one for Start2 and the other is Start1

Is your Hypertherm outputting 50:1 arc voltage ratio? Or is it 1:1? An arc detect failure sounds like it is getting to weak of a signal (I bet your hypertherm is set to 50:1, and the controller is also 50:1, which would result in such a small signal it would nearly be undetectable.) Example: your cutting with 100 volts. if you divide that by 50, your Hypertherm would be outputting 2 volts to the START THC controller. It then is also dividing it by 50, which would be .04 volts - much to small to be detected. Check your card, and your plasma source. only one should be doing the 50:1 signal.

Larry I have a Chinese cnc plasma with the chinese plasma unit as well. It has the xpthc-4 height controller. I cant get the starfire to fire up the plasma but the height controller will wen ya use the arcon button. Would you have any idea if im doing something wrong or they havent set it up. Thanks

Do this thc have both cut height and pierce height setting or can only set pierce high at start of cycle and adjust cut height by arc volt?

Siguiendo con la pregunta Sr Larry,el tema pasa por que mi maquina plasma no es americana es china y no se como sacar los dos cables que van al inversor,gracias por la atencion prestada.

Hi Larry ...maybe you could help me, your Vedic was very helpful. I have some of the same problem, I have no information on wiring diagram at all. Would you be able and willing to show me a diagram on wiring the 85 hypertherm to to the height controller to make it fire? Any information would help, thanks Quinn

Hi Mr. Larry and friends, can someone help me, because I want to check if my stepper motors is good, I have same controller of yours, but I trace the wire frok stepper drive to 15pin port plug XDIR+ and -, they put opposite, what will happen if the DIR + and - put in opposite?

hello, I have the exact same set up, I used to run a hypertherm 1650 powermax and everything worked great, now I changed to the 85 and I´m having the same problem, do you think the 1650 is set up different than the 85? any answer would be appreciated . thanks.

i have a the same controller and all of a sudden I got a >W+ symbol next to my auto/manual sign on the screen. This has disable the movement or starting of an operation. The manual says "X/Y+ limits, two positive axial travel limits connected in series, high priority. Please jump the signal to 24v ground if not use" . Does anyone know what this means.

Hi Larry! I have a newer version of this THC - the SH-HC31. I downloaded the manual for both versions but it’s barely understandable and the main part - settings makes no sense. Do you know what the values correspond to? I mean U, b, E, H, L, P and d? And how to set them properly? It looks like you’ve got it sorted out entirely. Many thanks for your help!

U: plasma mode, range 30~250 C: flame mode, range 3~30 E: sensitivity, range 1~10 b: initial location height/pierce, range 1~20mm H: maximum adjustment speed when auto cutting, 5~50 L: initial adjustment speed when auto cutting, 1~20 P: up/down speed in manual mode, 20~80 d: auto adjustment speed ratio (the bigger the value is, more slowly the speed adjusts)

My torch damge fully assembly video shear sir

So I am connecting Hypertherm 1/50 to 1/1 jp1 soldered on the board and 1/1 if I choose to run high voltage directly to the board then I solder 1/50 jp2 on the board. I think the Chinese thought people would not read the manual and input 1/1 voltage and they would have to replace that toasted item. Most people don't RTFM.

You can run 10,000 volts over a wire thinner than hair without burning out. As long as your current is very very low. 300v with very little to no current drain will not hurt it. Nor will it hurt a person. Unless that wire is thick and can deliver more current.

What controller are you running in conjunction with the thc ?? Looked at the StartSH controllers.. and they hade a bunch of them. =)

Thank you for the comment. No, I purchased the Hypertherm Plasma source here in the USA. It is a 220 volt - however they do offer a 480 volt version of it I do believe. It would be a three phase cutter, which I do not have in my shop. If you have 3 phase power, go for it.

I see, so if you are using sheetcam & Mach3, then you will are currently not using a START THC - since that would be your controller instead of Mach3. I use Mach3 on my CNC routers - but it doesn't allow for corner slowing or anything specific to plasma cutting. If you are only cutting 14 gauge, you most likely would not benefit from a THC. I turn my THC off when cutting that thin of material since my speed is so high I would not benefit from the THC. Hope this helps!

OK, that is what this video is covering. you need to make sure you are 50:1 out from your Plasma source in order for this mod to work. if you are 1:1 out then you need the THC to be 50:1. make sense?

Hi Larry, fellow sign shop and guitar builder here. I have added the same thc. From what I gather the unit is just turned on and off by the controller and it controls the height by itself. Is that correct? So there is a subroutine that allows this to start, bump the plate then the torch fires up?

@graffix

6 жыл бұрын

Kenny Grisham sounds like we have a lot in common my friend! As for the question, I hope I can answer correctly. The thc reads the voltage of your plasma source, and adjusts the height of the head to get the perfect voltage required to cut perfect. It is a one way communication from your plasma source - the THC deciphers the voltage and moves it up or down accordingly. You have to input the voltage parameters in the THC itself in order for it to float correctly above your steel. The process of it moving down and tapping the steel is only to set the ‘zero’ point of the steel. I hope this helps. You can give me a call if you need more assistance. A private message is all I need with your phone number. Happy jamming/sign making mister!

Kenny Grisham no, there isn’t anything between the two. There isn’t a ‘subroutine’ so to speak. The system functions the same whether or not you even use your head controller. Sounds like you need some more tweaking with the parameters, or perhaps it’s not wired right. I will email you.

Larry, thanks for the video. It's literally the only one I could find about this THC. I just bought this unit and am wiring to a breakout board and using Mach3 to control. Do you have more info on the 15 pin connector? The instructions are saying to connect pins 12 and 13 to a 24v source to control the Z up and down. Do you know if those pins are actually output pins? I'm completely lost as how to manually raise and lower the Z axis. The Chinese instructions are pretty vague. Appreciate any input or wiring diagrams/videos!

@graffix

Nicholas Newton the manual up and down on the actual z-axis is controlled via two methods. The first is your mechanical mode on the machine itself, the second is on the THC. The THC is controlled manually by your START software. Unsure on what pins. If you are converting to MACH3 for a controller you will need to replace the breakout board altogether I do believe. I had to on my router. I can say that it isn’t necessary, starts system is perfectly proficient for most applications. I am glad you found the video handy, like I said - there wasn’t anything out there for support. Good luck!

The pin out for the THC is strange, the only thing I'm stuck on is getting the Z axis to move.

Hi Larry, my name is Alejandro and I work for a metalmechanic plant in Chile. Thank you so much for taking your time to make this video and posting it on the web. It has been of great help for me and the company I work for. We have exactly the same CNC and THC, and the same plasma cutting machine Hypertherm. Without this video we wouldn`t be able to make them work altogether. I have a question for you (if you don`t mind): the CNC has 4 ports on the back: the first one (from left to right) is for the power supply, the second one is for the THC, the third one has two pins and the fourth has three pins... in which one should we connect the Hypertherm plasma? On the third or on the fourth port? We are having troubles figuring it out because the interface cable from the plasma has 7 cables, and none of the ports on the CNC has seven pins (they have 2 or 3) Any information about how to connect the plasma to the CNC would be of great help. Thank you so much for your time and help!!!

I am not 100% sure what your question is - but you will need to purchase the arc signal control cable from Hypertherm in order to connect your CNC controller to your Hypertherm plasma cutter. You can open the panel of the welder and hard wire them in if you prefer. Two signals are the arc signal cable (+/-). You will have to mount these on the ground of your torch, and the other on the positive. I hope this is what you are asking. THanks for watching!

Shane, the actual THC has a controller in the CNC control box. The wiring that goes from there to your THC is typically a 15 pin, or some light gauge data transfer wire. So I am guessing you are needing the wiring from the plasma source to the CNC THC controller in your panel. It's simple - if you have a voltage divider card built into your plasma cutter, you will come off of it with the positive wire. The negative comes from your ground clamp wire. So locate that on the inside of you plasma source and tap off of it. If you do not have a voltage divider in your plasma source, you will come off of your actual torch cable that goes to your plasma torch. You can locate it easy in your plasma source and tap off of it with some automotive wire (12, 14 gauge). That would send a 1:1 signal to your THC controller. That is the easiest way to do it, but be careful, that wire will be carrying some Volts since it's not divided (up to 300 volts - enough to make you piss yourself.).
