I don’t know the reading at that setting, it was obscured by a post on the cart. We should note that number here. Current setting should also point (mostly) up, about 25A for most thinner material, like 16gu plate. |

Ideally you want the height of the cut head to be about 1.5 times the thickness of this gauge above your material. |
