Looks like the electrode was not centered somehow. Which makes perfect sense after seeing the cuts. The arc was no where near the right shape as it was trying to blast out the side of the nozzle.
Make sure you aren’t over tightening the retaining cap.
I wanna see inside the nozzle too now.
I noticed that too!
I wonder if it was improperly installed.
Silly question but was it installed correctly?
Before everything is tightened down, there will be a little play before the nozzle sits perfectly along the swirl ring. It’s possible that you tightened things up and the lip of the nozzle was caught forcing you to think everything was correct.
When everything is seated correctly, the electrode will be perfectly center behind the nozzle.
Just a thought.
I say this because when I played around sorting things out, I noticed it too upon my first installation.
Man, at this point, anything is possible. I have tried finecut consumables about 4 times with the same result. I cant recall having bad cuts with the regular consumables.
Maybe I am psyching myself out at this point expecting to fail with the finecuts and sabotaging myself.
Before I cut this pattern agaIn, i am replacing all of the consumables and start at square 1. I will pay extra attention when installing them.
For kicks, play around with assembling the consumables.
Just place the swirl ring, electrode, and nozzle in the retaining cap and you’ll see how they “fall into place” allowing them to self-center.
LoL it sucks when the indicators point back to you being the problem. I’ll mess around with it until i get it right. At least now i no longer feel like I’m cursed with the finecut setup.
People have made worse mistakes.
I read somewhere that Hypertherm says to finger tighten and then back off an 1/16th of a turn. They do not want those consumables snug. You don’t want them rattling either.
Don’t feel that we are looking at you in that regard. We have all done things that we don’t necessarily want to recall. It is all part of the process.
Thank you for the photo. This nozzle is in oddly bad shape . what is going on with all the abrasions on the surface of it ?
did you try to clean up the end of the nozzle somehow?
How much cutting was done on this nozzle?
Is this a picture of a 2nd nozzle ? or the same nozzle blurred. it looks defective. offset hole like others have mentioned. Or maybe parallax?
how many finecut nozzles were in the pack? do they all have this offset defect?
@TinWhisperer the 2nd pic in your response is the electrode. No i did not try to clean it up. Like I said, scattered was going on trashes them. They were new at the beginning of the cut.
hard to tell from the angle
this is a different electrode then you used with the 45amp standard consumables?
I would contact Hyperthem and get them to send you non defective product. send these pictures to them.
Just ordered 500 worth of consumables from baker gas this morning/night. I’ll have to check over the electrodes carefully .

Yes. I swapped out the tip, electrode and deflector.
We were thinking it was installed slightly crooked. Are you thinking the hafnium was not centered in the electrode to begin with?
I think the inside of the nozzle shows where the electrode was contacting it indicating it was crooked.
Well the only mistake I can recall that I ever made was a pretty small one. You might remember I spent a hour messing around trying to get my table to cut and could not figure it out. So I called tech support and they said they would have to think on it. Come to find out I never plugged the air in. I did call them back and told them to quit thinking about it, that I solved it all on my own!!! (who needs tech support)Listen, to anyone reading this I am not trying to Toot My Own Horn, but Toot Toot
yes. if not that electrode should work fine with a new nozzle.
I guess if we got a good enough macro photo you could see the discoloration showing the hafnium isn’t centered.
