The best way to get information, service or to get questions like this answered is to contact Hypertherm directly. There is a Technology Update Addendum for all of the HPRXD systems (the 130, 260, 400 and 800) that you can download by going to the Choose your region and language | Hypertherm website , then clicking on downloads libray (top of page), then choose the system (HPR130XD) then go to manuals, then the technology addendum.....which can be downloaded as a .pdf. This manual has the newest cut charts for the thin stainless capability, as well as other enhancements for higher powered cutting. In the meantime I will check with the mechanized plasma group at Hypertherm to determine why this info was not shipped with your system.
If you send me a direct email at jim.colt@hypertherm.com I can email a copy directly....it is about 2 megabytes.
