Recently got the .08 consumables from primeweld for my Cut60 as I’ve been using 1.0 Amazon consumables.
First time I used them, there was a weird screeching sound and the cut was jagged along the edge, like a serrated knife. Very uniform jagged edge and it led me to think perhaps something with the swirl ring but it was gone the second test I ran so I let it be.
Fast forward to today and I change consumables and I’m having a similar issue, almost sounds like if you’ve ever let air out of a balloon slowly by stretching the end and making a squeaking sound. Also the arc is changing colors quite a lot during the cut. I also ran this cut as a dry run just to make sure the table itself isn’t making that noise. Not sure if I will have to deal with this every time I change consumables?
