I’m running a primecut60 . Cutting 16 gauge at 30 amps using .08 tips in an IP60 torch. Of course I read that most people are cutting this at 175-200 ipm. My question is about very fine detail and small cuts. if you were going to cut something as small as a 1/8th hole how much would you slow the cut speed down for that ?
I wouldn’t try to cut a hole that small (or smaller that 5/16 inch for that matter). The pierce hole (and hardened steel) will mess up the accuracy. If you want an accurate hole ‘drill’ a ‘peck’ to mark the center of the hole and drill it out later with a real drill. There are plenty of examples on the forum. Search for Drill and Peck…

True for mechanical parts but okay for artwork where the work hardening of the hole edges and any mis-sizing due to sloping sides to the cut won’t really matter. But for anything you’re looking to put a bolt through the peck & drill approach is the way to go.
Yeah Im referring more to art work. Just trying to figure out how much to slow down for tiny details.
These were cut out of 16g cold rolled with a cut60 at 100imp, 30 amps with 40amp sheilded consumables. Not super detailed but some parts got pretty tight.

Those look great. Im just starting with my table so i have alot to learn. Do you have any general feeds and speeds you can share with me? Im starting with the chart included with the primecut but i seems to need some adjustment.
I too am just getting started. I made my tool list in sheetcam with the book specs as a base line and figured in would dial them in as i go. 16g is the only one in have changed at [ has to make some Christmas presents lol ] so i have feedback other that the 16g. Lots of guys have more knowledge than me fortunately so im sure someone will chime in.
