Made an adapter

My TIG torch is 5/16-24, and my carbon fiber TIG cleaner brush is M6x1. I tried it out today and it worked well.

Do you just dip the brush in acid (or Surfox)?

Run low amperage of AC (like ~30A)?

I’ve been thinking of this.

I have a gallon of commercial cleaner coming, I dipped the brush in Ospho for the test. The cleaning machines run at about 5 amps if I'm not mistaken. I tried up to 10 just to see, it gets pretty sparky at 10, and have the HF start off.
