Powermax 85 sweating

[SRdesign]

My last cuts I ran it at least 20 minutes nonstop before letting the power unit have a break and cool down. It was an extremely hot muggy day and I felt the torch body after a wide open, torch on full time 150 some volts according to my screen. Like I mean all the stops pulled all it would do. I could put my hand down by the retaining cap no problem. I started this idea December 2021but never bothered posting before cuz I thot it was just a flaw with my machine. Also thot some folks would think I am fooey

Thank you for the feedback!

For whatever it's worth, I cut out 4 ears 1 3/4" thick, 4 at 1 1/2" thick, and 2 that were 1" material. Around 7 hours arc on time running wide open on that project. No problems with torch overheating as of yet.

Interesting results and how it works to improve 1” to 1.75” thick material cutting yet for ROKCRLER it did not help with thin gauge materials. It would be interesting to know if the cut heights and how the nozzle moves in his case with fine cut consumables comes into play here.

I'd be interested in hearing @jimcolt advice on this.

I have since removed the added o-ring and went back to OEM setup as i did not find much improvement.
I did however PM the table and torch with new grease/bearings/o-rings and cuts are good again.

only issue i have is 20ga-26ga galvanized... i hate the stuff...but money is money.

That is freaking incredible. I cant even do near that good on 1" with my powermax 85. That blows me away. What was the IPM?

I set it at 2.5 ipm as a starting point, ended up using 4-5 ipm. I discovered a 75 cent powermax upgrade one day a year or so ago from frustration that i will try to post when i have time.It will make yours cut like mine. I will probably post it in the hypertherm section tho.

I like what you've done there.
If you are considering adding an oxy torch, take a look at this chart:
https://www.koike.com/documents/Product ... -13-21.pdf
Scroll down to 106d7 tips (I use these) and 1 1/2" plate is cut at 18 IPM
Yes, they run at 100 psi of oxy, but use less volume than normal tips.

Thanks plasmadon, some reason the links dont seem to go anywhere tho, I am interested tho. What setup do you have, did you set it up on your own table, and how do you work touchoff and height control? I am looking at using sensor rings... not sure what folks do and use.

I have a normal chinese made one, with the Fangling controller.
It came with a torch, I modified it to have the valves on the controller instead of at the torch (5x10 table)
I also bought quick couplers ($100) to quickly put the torch on/off.

I don't know of anyone running an automatic THC on Oxy, been in many shops, and all do it manually,
it's not nearly as critical as with plasma.

follow the link, go to gas equipment, then to cutting tips, then to lower left "Literature"
i can't figure why the linky doesn't work, and can't figure how to edit a post after I post as well.

I addressed it:

surely you can see the main website of "www.koike.com" ?

Does anybody know how to get the the mounting sleeve off. I want to clean in there. I took the three little screws out and do not want to force it. I cannot even get to the wire connector for the cap sensor switch as it is illustrated on page 6-11.

I had taken mine apart and here are some images. after the 3 screws you push the outer housing toward the tip (nozzle) end.

[TJS]

Thanks Tom,
I did not unscrew that small collar. Maybe that is why I cannot get it apart.

[acourtjester]

I took my apart to make it a short machine torch, did not like it so put the center extension tube back in the torch (full length machine torch).
you may need to loosen up the cable clamping at the other end of the torch so the housing can slid back on the cable.

super sujet qui va certainement me réconcilier avec mon PM85. j'ai des coupes médiocres sur du 15mm , je pensais a un manque d'air a la base de mon installation mais certainement que cette astuce pourra bien me solutionné bien des tracasseries. dés que possible ,je teste cette possibilité.
merci pour vos retours .

great subject which will certainly reconcile me with my PM85. I have poor cuts on 15mm, I was thinking of a lack of air at the base of my installation but certainly this tip could solve a lot of hassles for me. As soon as possible, I will test this possibility.
thank you for your feedback.
