Looking for a printable cutting chart for Hypertherm 45

[Danno]

I'm finding lots of charts on the web, but it seems like the settings are all over the map. Could this be because they are for different Hypertherm models?
I would have thought that the settings would be fairly close from one machine to another, but I'm finding charts to be 20 volts different for the same material.
Anyhoo, I'm sure the chart in the Hypertherm 45 manual is probably the most accurate, but I would like to find one that I can print off to mount on the wall beside the computer that has my CAD and Sheetcam programs.
If it's in colour, I may even put it in a frame !!
Thanks, Dan

I just used a couple pages from the .pdf version of the PM45 manual from Hypertherm's website. Printed them off, laminated them back-to-back, and keep my "cheat sheet" on a shelf under my table.

Edit: This should be the one. https://www.hypertherm.com/Xnet/libr...170&format=pdf

Thanks Carl;
Good idea !! I was going to scan my own manual, but this is a whole lot easier.

You can actually copy the files and save them on your computer from the .pdf files of the Powermax45 manual.

Hypertherm also has an "xnet" site that is accessible by our customers....you will have to register for the site ....but there is a lot of detail on the site...including downloadable cut charts. Here is the link: https://www.hypertherm.com/Xnet/login.jsp

Thanks Jim;
I downloaded the charts from the Hypertherm website, but have one last question !!
I notice the settings are different for "Sheilded" and "Unsheilded" consumables.
Am I missing domething here ? I thought the consumables were all the same except the front deflector. I realize that on my machine torch I need to use the machine deflector because it doesn't have the extended tip.
Not quite sure what they mean between sheilded and unsheilded though !

edit;
I looked through the manual, and found that there's a listing for both shielded and unsheilded consumables. What's the advantage of unshielded?
Makes you wonder why thay would even bother to make the 2 different types unless there was a major advantage one over the other.
Is Unshielded even available in North America?
Thanks

The only advantage to the unshielded consumables is that they make the front end of the torch a little more "pointy".....which for some 3 dimensional cutting applications benefit from, ie., the torch can get closer to the work in tight places. The disadvantages of unshielded....a lower energy density, softer arc, worse edge angularity, shorter life, thinner piercing capability.

For 99.9% of the applications....use the shielded consumables for mechanized cutting.

-The shield electrically isolates the nozzle from the plate allowing for thicker piercing.
-The shield minimizes double arcing in the event of a plate collision....saving the integrity of the nozzle
-The shield's inside shape works in conjunction with the nozzle shape to create a conical secondary flow pattern than inproves nozzle cooling and increases arc energy density...resulting in longer nozzle life and squarer cut edges.

Conical flow and shield technology are pateneted by Hypertherm....and are a major breathrough in air plasma cutting technology.

I've used unshielded consumables on my Powermax 45 (the PM30 parts). They cut nicely on thin stuff, but last probably 1/4 as long as the 45A shielded consumables do.

It was fun to try, but I'm not really going to use them any more.

Thanks for the reply;
Up to now I've been using the unshielded chart without even knowing.
I was piercing at .200 and cutting at .080, and had good results. I will try the recommended pierce at .150 and cut at .060 on my next job.
