Plasmatorches are as good as their electrodes and ulifetime

a limited life of the electrodes for a given power level and torch size has limited the use of torches in commercial applications.
Another important factor is that in most industrial torch applications, the replacement of worn electrodes results in significant lost operating time for the process. Hence, longer lasting electrodes are desirable even with somewhat added cost for such electrodes.
During normal direct current operation on copper electrodes with the upstream electrode being the anode, the life of the upstream electrode may be less than about 100 hours and the life of the downstream electrode may be less than 300 hours. Oxide particles coming from the upstream electrodes tend to cause unstable torch operation. Copper oxide is stable at high temperature. These small particles enter the gap between electrodes, causing periodic short circuits and damage to the gap area. Reversing the polarity does not avoid the problem. Torch operation on alternating current alleviates the gap shorting problem somewhat but the electrode life of the two electrodes is merely made substantially equal at about 200 hours or less.
The objective is to extend electrode life 

Plasma torch with extended life electrodes
did we succeed in this ?
the long delays seem to suggest we didn t got it completely right and that we are still experimenting .
So are we ready for industrial roll out or not ?
we will find out soon enough .
I hope pyr proves me wrong .

The village idiot is attempting to imply that it is smarter than all of you incessantly. T-Chick you fail miserably on a daily basis. You are like "Side Car  Bob".  A multibillion dollar company is factory testing the torch because they are what, bored? You want them to call you and pet your bald head and say, theee, there little one, we've got the physics data on the ...more

Unloved Casanova ghost., we are trying to talk about the role electrodes play inthe performance of torches. pyr must overcome  the challenge of the melting electrodes if they want to proceed to industrial production. Suitable Torches stable and reliable 24/7 just the opposite of you . the result have to be reproducible 24/7. i don t say pyr can t come up with a solution . what i see ...more

Please let's ask Peter to explain this. This is a legitimate question from shareholders. How often anode and cathode need to be replaced if the plant operate 24/7, and how to replace 
Comment by windywolf on Mar 25, 2022 8:40pm
You have every right as a shareholder to ask any question you like pertaining to the subject. So why dont you send a email to Peter and ask him that exact question? If you do. I would much appreciate you sharing Peters reply with the rest of the board. Thank you. go pyr.

Peter mentioned in Q &A that torches are plug and play whereas the plant doesn't need to shut down to replace or maintenance etc.   The after sales service should provide great revenue source.  https://www.pyrogenesis.com/products-services/plasma-torches/apt-hp/ Cathode: up to 1000 hours Anode: up to 500 hours Long and strong PYROGENESIS

It may just be a cost of doing business just like having to order more fuel to power what fuels their current torches. If PYR's torches are cheaper to operate the current torches they will buy. Try filling up your car with gas the fuel costs must be unbelievable let alone what the cost will be when their governments bring in carbon taxes to get the companies to change. It's all about ...more

You’ve been in this equity long enough and should know the answer is ALREADY known. It was ALREADY discussed lonnnng ago with the electrode life span. Peter has answered it in one of his MANY interviews. You are diligent.. You’ll find it.
