I just tested mine and that is normal as long as all the o rings are doing their job. I would replace them just to ensure. Does it drip coolant at all? I would remove the torch and inspect make sure the insulator is not cracked. They are known to fail. Old age, over tightening consumables, torch collisions. I bought my table from a manufacturing company the table was in use daily. They got a few years out of them. But they did need to be upgraded attached is the recommended replacement interval for my machine. Yours is probably the same

Thanks , the fact that the cooling was coming from the side ( horizontal) it seems normal . But the cooling liquid parallel to the electrode in the picture made me think it is not normal but I'm not sure because I never tested a good working torch like this , but as you say it is normal, it means I have a loose o-ring or just some filters to change in the system.
Thanks for the reminder , there is an analog of that table you attached in maxpro 200 Manuel , with compenent element reference and when to change it.
Thanks for your response, I will post here if we found a solution to this.
For now we ordered some o-rings and filters.

Torch body

From the picture I took yesterday, new consumables after 15 piercings.
Arc ignition is from the side of the electrode now , not from the center , why is that ? It is because of the cooling liquid interfering with this process ? ( The cooling is not conductive , how it can affect the arc ignition!? I don't know).

15 pierces… sounds like your doing better. Is this a new setup? Or had the machine been running in the current environment for a long time? Not sure how many arc hours your machine has on it but has any of the recommended replacement items been replaced? Adjust gas pressures and test. Try unscrewing the retainer cap a half turn, run with THC off an test

Today in work they changed an element in the I/O PCB that I attached in the picture, I guess it is a diode, ( I don't understand these electronic elements, correct me if I'm wrong ) , after changing this elements , the plasma started working perfectly. So the cooling liquid on consumables and gas quality wasn't the issue. Thanks anyway for your tips and advices .

Interesting.. I learn something new everyday. Glad to hear your back up and running! At least the machine got some preventative maintenance in the process

Me too , I have many questions now about this electronic elements and the relationship between the wet consumables, as I tried not cleaning the electrodes and I let them wet for a day off in weekend, after that I tried to cut but same error 0-20 , I got one piercing or more only after cleaning the wet consumables.
Now the plasma is working perfectly and it doesn't matter wet or not wet consumables.

Seems the main deal there is the coolant will break down over time and become conductive leading to hard/ failed starts. Makes me wonder if coolant break down over time leads to internal part failure making things work harder fighting for an arc. Wet seems fine as long as it’s not contaminated or conductive. Ahhh so much to learn. Post any follow up findings you learn along the way. Any tips and tricks go a long way.

I will be posting if I noticed something else.
For now the plasma is working perfectly, not missing a single piercing.

That's great to hear, glad you were able to get it resolved.

I wonder if you have an idea on this ?
I'm searching for documentation in internet that explains every element of the ignition console for hypertherm maxpro or analog of this hypertherm but I couldn't find it.
In the picture I noted in a red circle the spark gap in the ignition console ( in the hypertherm manual they noted to check this for 0-20 error).
But I'm not sure about all this. It is weird that there is no in depth training courses or documentation for hypertherm plasma in internet, knowing that it is leading company in the world in this field. Maybe there is such kind of documentation in the internet somewhere. I don't know.

No I have no experience or information to share with you on that. I can understand why they wouldn;t make this information readily available on the internet however if you can your hands on the complete service manual (not operators manual) you will likely find ,ore information on that and testing procedures.

Hi.
Do I understand correctly that there was no spark on your two SG1 and SG2 elements named "Spark gap electrode"/discharger when there was no ignition? or it was, but there was no arc ignition on torch.

My coworker took a video of it before they change it , I need to ask him about it , I'm not sure if there was no spark there , but after changing these two elements, the plasma started working perfectly. But in your second video I see the plasma arc light on the plate , in my case there was no plasma arc at all when the machine fails and gets 20 error .
I don't know if we are facing the same problem , you can change these two elements, I don't know what they call them exactly, they cost very cheap.

Possible cut height, gas, grounding issue. Mine will do that if my IHS isn’t set right or cut/ pierce height is set incorrectly. I must have my arc fail setting lower then yours, mine will only attempt to fire once. Yours tries multiple times

MaxPro200 error 20: The epilogue

The high-voltage hose breaks through.
The spark has a breakdown voltage of 3500-5000v.
Check the hose with a breakdown device.
We inserted the high-voltage hose into a rubber hose with a larger diameter.

I'm glad that you finally solved it.
What is the purpose of the rubber hose ?
