IJDid you un - screw your tip on the torch and check your nozzle and electrode?
Your settings are plenty slow and high enough on the Amperage to cut .185”
45 A would cut 1/4” steel and thicker…
Once you check your consumables can you manually fire the torch with MACH 3?
I’ve found through testing with the RAZORCUT 45 that .070” - .074” torch height has worked extremely well for me.
Also with 45A setting I’m assuming your using at least a .9 or 1.0 consumable nozzle as well ?

Picking a material thickness and running a cut test I’ve found is absolutely essential in getting any type of quality results.
I’ve now got my machine and consumables
Recorded for the 4 material thicknesses I cut most often
