For some reason the plasma isn’t making a clean cut through the material, I’m using a 45 amp tip to cut on 3/16 material, it is cold where I’m at so the weather might be interfering with my air but other than that I’m at a loss.

You need to look at some posts people have made and see what information they shared so that someone can try and help
Lots of reasons, and you’re not providing detailed information, troubleshooting you’ve done, checklist you’ve gone through (or not).
I cut lots of 3/16" and it’s always clean and dross free with a 45 amp consumable set.
Please provide more info.

Without guessing about everything that is possible (work lead attached to metal, air is sufficient both in volume and dryness, plasma cutter working correctly) lets get some details:
The more information that you can supply, the better we can try to help. We need this:
• any recent changes: new electrical equipment, generator problems, circuit breakers tripping, flickering lights
• Do a sample design, something simple like a 2 inch x 2 inch box with a 3/4 inch circle in the middle of the box. Manufacture the gcode and attempt to run it on your setup. Report your results and share the gcode.
• metal thickness/type: you state 3/16…assuming steel
• work lead attached to shiny/clean metal
• work lead, torch cable, THC cable and printer cable to the enclosure are not touching/crossing paths nor coiled up
• copy of the gcode of your test file: I notice you have your kerf width set at “0”, why???
• photo of how your torch is mounted
• photos of your consumables
• photo of your VIM box so we can see what leads and connections are used
• What plasma cutter are you using? Are you using OEM consumables? Are they standard or fine-cut consumables.
• What is the brand of the consumables (not the machine they are labeled for)
• air quality and quantity (pressure gauge at the plasma cutter), what methods of drying employed. You need 6 CFM @ 90 psi and it needs to be dry.
• Smart Voltage on nominal voltage
• Have you had any successful cuts with the current setup and metal type/thickness?
• Can you fire the torch manually thru FireControl?
• Is there any connection issues with the IHS contacts in the z-axis carriage?
• Are you using a laptop and is it plugged in or running on battery only? Fully charged?
• Cut height: have you measured what your cut height actually is when you set it at 0.06 inches for normal consumables and 0.14 for Hypertherm SYNC consumables?

Alright, few things I can mention seeing your F3D file.
Unless you own a Hypertherm, many plasma cutters will not pierce through 3/16" with a 0.5 pierce delay. My PrimeWeld CUT60 would need 0.7 or 0.8 second pierce delay to cut through 3/16" and it was only after I switched to a Hypertherm that I can use 0.5 second.
Second, your speed of 85ipm might be too fast for any machine running a 45 amp consumable set.
Have you dialed in your machine at all?
Lastly, and this is just constructive criticism. You should steer away from using Face Contours for profile selection.
You should choose geometries yourself, implementing different rules for lead in/outs for the best possible cut quality. In short, using the same rules for all geometries can leave some to exhibit “burn” marks on a lead in or out. I often cover this subject when I do Zoom meetings with people and after they learn that, their cut quality becomes significantly better.

It was the air pressure, ive had issues with projects not finishing due to the kerf width being to big so it was set to 0, since then ive changed it to its correct value i just forgot to switch it for this project, thanks for the help.

Good deal. Thanks for reporting back.
