I usually use mdf and acrylic sheet but today when I tried to cut a cork, there was a flame and it burnt the material pretty bad so I will probably not use cork again.
But the problem is that when I cut an acrylic sheet which I use, it flared again. I don’t know why it is happening since I never had this problem before.
Should I be worried or it is just normal to see flames like this?
I will attache the video I took.
Any advice would be appreciated.
