I finally found the link (Razorweld Cut Chart), but honestly, the chart was not easy to use, and I didn’t want to risk wasting a $100 steel sheet trying to figure it out. I ended up using the cut chart provided by Razorweld and posted by MO-Hacker, specifically for this cutter. (Razorcut 45 cut chart) Our max ipm is 300, but I cut mostly 10ga Mild Steel anyway. By using Razorweld’s chart for “optimum travel speed” (0.50pd)(98ipm), I get perfect cuts every time. Which is awesome, because the basic settings provided by Langmuire’s tutorial videos made terrible cuts, and half the time didn’t even pierce.
Edit: I’m actually having some trouble with my pierce delay today, but other than that, everything is perfect using Razorweld’s chart.
