Severe bevel on cuts

1

don’t know whats going on… when I first started cutting I cut 3/16" and 1/4"steel like butter…but now when I cut any parts out, I get severe bevel . the only thing ive changed is my compressor. ive upgraded from a 20 gallon to a 60 gallon. any help would be appreciated

Is the bevel to one side of the part? (top or bottom)/
check the torch for squareness
torch might have been bumped inadvertently
also, what psi are you running?

3

its straight and 90 psi

4

My money is on an angled torch. I think there was a link on here somewhere but I cant seem to find it about squaring up your torch. Its something that changes constantly with consumables being swapped out. Unless you have a machine torch.
How are you squaring off your torch to the table? Also , double check to see if your gantry (X) is level. Mine was like that at first and as much as I tried to square the torch , it was constantly cutting thicker metal to one side …until I fixed the gantry.
Hopefully somebody else can chime in. I know its frustrating to get everything ready, designed, and cut only to find out you have a small bevel on your piece .

possibly swirl ring reversed? I wish they were marked.

Swirl ring?? Don’t know what that is…

Check the torch and is square… I adjusted my x gantry cause the torch was higher on the outside.

any improvements?

The Swirl ring is a brownish ring that goes around the electrode and rests against the tip inside the nozzle. It has to be oriented in a certain direction… you have a 50/50 chance of getting it right. lol I get it wrong sometimes and it does affect your cuts for sure. Here is a great video that a member posted. Very informative Plasma consumables, maintenance and such. Video inside

swirl ring info is @3:18 in video. May be the issue

Have you tried a new plasma cutter tip? My problems with bevel cuts have always been from tip wear. An almost imperceptible defect can cause a lot of issues. 90 psi sounds high for most plasma cutters without internal regulation.
