Need Help!- HYPERTHERM PM1250 cut chart input

[WSS]

I am putting together a bunch of cut charts for the HP PM1250. It will include mild steel, stainless steel, aluminum and the fine cut chart. These charts will not include part numbers for consumables (maybe later on a separate sheet). I am looking for info such as cut height and any other proven ideas to put in the empty sections at the top and bottom (text).

It would be nice to hear input from users here on the Zone. I will try to get these up in a week or so, provided the info is clear. I will put it in a zip file and post them here in this thread for those who need or want them. I will include both a regular facing and "mirror image" files for paper or transparency printing. They will be under letter size to fit most printers.

Jim Colt, please chime in if this is a good idea or you have some input. I won't ask if your ideas are proven (lol).

Edit: Added CNC Zone logo to chart.

WSS,
It's interesting. Do you have pdf file?

Mongkol,
A pdf is no problem. That is the kind of input I am looking for. I had not thought to save it as a pdf. I will post it next week as a pdf as well.
Thanks! WSS

Any other ideas? How about pierce height and delays? Should I go by the manual? I would like to get this finished this week some time.

WSS,
I agree to add pierce height,pierce delay,cut height,air pressure for the kind of material.
Other?

Monkol,
OK, I will add the pierce heights according to the HP manual. I'll get them put together this weekend and PM a pdf to you. It should be about six pages. I will remove the color from the background to work better as a pdf, unless you have a preferred color? I generally use blue for LP oxy torches and red for acetylene torches. I am not sure if plasma has a reference color?

Its a good idea....however you can download these charts from the Hypertherm website right out of the operators manual for each system...they are in .pdf format.

I would suggest leaving part numbers on the consumables. It is very hard to tell the difference between say a 40, 60 or 80 amp shielded nozzle if you don't have a part number for reference.

It would ge nice to see what Hypertherm recomends for the pierce heights. My manual doesn't even mention pierce heights.... Why did Hypertherm leave out such important info? I just learned that pierce height should be 1.6 to 2 times the cut height; But, I haven't seen it in a chart yet. Thanks, Aj

[WSS]

AJ,
Can you put together some info regarding the pierce heights? I just realized it is not there! I see the cut height but not the pierce heights. And if possible some info on delays? I can modify if needed but it would be good to nail it on the head the first try. I would need it for aluminum and SS as well if possible. I also have a fine cut chart to put together as well. So I may be further off than I think.

THANKS for any input!!

here is a chart i will use when our table is up and running. I will have to experiment with heights and modify the chart when I am sure of the specs.

I'm wondering what Hypertherm system you have? My manuals for both the Powermax45 and the Powermax1000 list pierce heights. Perhaps you have an older manual from before they were on the list.....let me know and I will check it out.

The rule of thumb for pierce height: 1.5 to 2 times the recomended cut height.

I've just downloaded the other "powermax 1000, 1250, 1650" manuals and basicly they are all the same. They leave out the pierce information.

The Powermax 45 seams to be an updated manual with pierce info in it. It also goes a step farther and explains how to optimize cut quality and explains torch height and taper. This was nice of the Hypertherm guys.

Hypertherm recommends a pierce height 2.5 times higher than the cutting height on the Powermax45 reguardless of amp and thickness of metal.


I wish Jim would put his 2 cents in and give us the rule of thumb on pierce heights for the 1250and 1650 machines.
