VI used hot rolled as it was cheaper, but cold rolled cuts better and there is no mill scale to clean off, its slightly more in cost but it’s made up with the cut quality and less time to finish clean.
Those settings are a base that they mention in the set up and not what will yield any quality result.
If you look at the post I did on .105 cold rolled, you can see there is a long cut followed by direction changes then quick direction changes.
Speed typically slows when the cutter changes direction and so might kerf widths and results. The 70 ipm had almost 100% retention of the 0.031” Kerf width through the turns of the cutter so I use that and the rest of the settings all the time now on .105 cold rolled steel.
I design all my artsy stuff in INKSCAPE. when I have the design finished I create a filled circle the same size as my test cut result, in this case 0.031”.
I then run that circle around the entire design to give me an idea if there will be cut width issues and clearance issue. If so I can tweak the sketch/designs lines using the node editor and negate any width of cut issue before I run the file on the cutter.
You can also up the ipm speed and AMPS to get through the cut file faster On thicker stuff but that’s another test cut palate.
70 ipm yielded fast enough cut result and great quality.
I have some 18 & 20 gauge cold rolled on the way and will be running the .6mm consumable ,test cuts on both.
I buy all my sheet from online metals.com
I have numerous metal supply shops around as I’m in RACE CITY USA area in N.C. BUT NONE HAVE COLD ROLLED in the gauge I use?
Go figure. And LOWES IS over priced for tiny sheets, let alone anything of decent size. And where there steel comes from I’d guess CHINA
I buy 24x24” sheets or a 24 x 36 they fit perfect on the table.
You have to take the table for what it is.
It’s a hobby table/ light commercial table for a small business as LONG AS YOU, take time to dial it in and do the maintenance on it regularly!!! and realize without THC your quality is solely dependent on your effort to maintain and dial in the cuts with testing that is specific to your Plasma cutter.
If you buy a better quality Cutter like a Hypertherm you’ll get better results but still need to dial it in and run test cuts time and time again.
I’m very happy with my table and the results with my RAZORCUT45!
Just takes test cuts. To dial it all in and you get awesome cut quality …
