How thick are you cutting? As thick as I can and still get acceptable cut quality!
How big is your table? 96" x 180"
Why the upgrade? Bigger, faster, better!!340058 :)

That sheet is 96" x...

I'm thinking of updating from a PM85 to the PM105, my 85 is about four years old with a little over 200 arc on hours, is there any updates or improvements coming up in the next couple months that...

Bill is spot on on his recommendation!
I have switched from an Thermal Dynamics A120 to a Hypertherm Powermax 85, I would estimate at least 50% better consumable life!
No regrets there!

I have been looking at these for while and it looks like a good way to transfer those hard to draw cardboard templates that come in.
Has anyone had experience with them? Are they as simple and...

I will have to second that!
I went through the same thing with TD, I wouldn't say junk but no where near what the Hypertherm Powermax 85 is!
I would say consumable life is more than 4 to 1, more...

Have you tried going back to the 100 amp parts? I have had similar problems with the 85 amp machine and I think some times it is just a bad set of consumables. Change them out and all is well.

My...

Yes, the pause is before the torch off command.
I am using a modified MP 3000 post.
It skips the tab and then sits with the torch firing for the programmed delay. This is a fairly recent...

Thanks Jim, I will get you something later today.
I will attach a picture of a 3/8" a36 part I cut last night, 45 amp, with tab.
I will also add the code from that part.
This has not been a...

Thanks Jim,
I can't help but think there is something else causing this as this doesn't seem to be a wide spread problem.
As you can see from the last pictures even with a pause at end of cut it...

Thanks for the reply Jim,
I am using sheetcam and Mach so Torchmate tech won't be much help. Also this is not limited to stainless as I have the same issue with steel but not as bad.

This...

Jim, if I remember correctly don't you use a Torchmate machine? Have you experienced this problem on your machine or does Torchmate have a provision for a slow down function?

I didn't have this...

Today,s update.... These pictures were cut with a .5 pause at end of cut. All else the same as before. I honestly can't see any difference.
I will contact Les from Sheet-cam to see if there is a...

Thanks for the replies, It looks like I will have to live with parts tabbed in as Sheet-cam has no provision to slow the cut speed at the end of the cut.
I have a .5 sec. delay programmed at the...

I have been having this issue for a while now and finally have some pictures that show the problem quite clearly. This is 1/2" 304 stainless, cut at 85 amps, 34 ipm. travel speed. As you can see...

Thanks Jim for the informative reply with little info!
I don't know much about it other than it is coming up for auction soon.....
I'm sounds like it's way out of my price range even if it could be...

There is a AKS ACCU-KUT machine with a Hypertherm HPR 130 coming up for sale soon and I am looking for input on this compared to a Mach 3 controlled machine with a Powermax 85.
I know it's a step...

Part tab update.......
In reading through the forums on CNC Zone I stumbled across a thread by stout about angle
kerf cuts and realized I have been having kerf problems for a while also. So on
a...

No, nothing like that..... It looks like the arc just jumps over the last bit on the bottom leaving an uncut tab.

Yes I do have a delay in Sheetcam.
I don't have tip saver or antidive. (MP 1000C)
This happens as the cut passes over the original cut and into the lead out area.

I am using a machine torch with the correct consumables listed in the manual.
I have not had good luck with the maximum speed settings, but the recommended settings seem to be spot on!

I was...

Thanks Jim, I have CandC controls using Sheetcam for programming.
I have tried lead out and no lead out with little success, it still jumps to the lead in cut area leaving a small tab.
These parts...

I have been having problems with parts not cutting off completely. It looks like the plasma flame jumps over a small tab of steel at the bottom of the cut as it gets to the lead out, leaving it...

"If you had a Hypertherm...I could offer much better advice!" True statement!

But if he had a Hypertherm he wouldn't have these issues!

I can safely say that because I have been there and now...

WSS,
As you might remember I had a TD A120 and the best I was able to get was around 300 pierces on 3/8 ar plate.
I'm not trying to sway your decision........ but I just changed out a nozzle and...

Hmmm...... I understood it to be Z axis speed.
None the less I think we're on the same page!
I typically set the Z plunge rate close to the same as feed speed and have close to a 45* lead in....

Neil, If you don't mind me asking...... "With 7 IPM on the lead in"...
How or where in Sheet-cam do you set that?
Or are you referring to "plunge rate" ?

Thanks, Steve

Millman, I don't remember what cam software you use? Is it Sheet-cam or something else.
I am anxiously waiting for a report on the dome loaded reg. too. This is something I would like to do in the...

That cut was done ccw on the outside. I bumped the feed down as it was cutting till it cut through then readjusted the volts till the height was right.

I had just done an order of parts all 3/8"...

"Your Powermax65 will cut 3/8" material at up to 78 inches per minute"

WOW..... not here.

New nozzle and electrode will not cut through at 68 ipm. I just tried it.
The book lists 68 ipm as...

Sorry, I guess I didn't define it too well. 3/8 a514 (T1) plate clean surface.
Cut specs out of the book for 65 amps.
My machine is a Koiki 1200 converted to CNC control using CandCnc THC.
It...
