Jim,

Previously you stated that the bolt holes have to be a cut a good amount larger than the bolt size. What sizes were cut on the sample that is displayed in the picture with the bolts sliding through your holes. I am cutting with a Powermax 125 on 3/8'' plate creating 1/2'' bolt holes and would like to know what kind of over sizing I should expect to have to implement. Additionally, should I expect to see better cuts while using the higher (125A) amperage settings on the power supply or with the lower (45/65/105A) settings?

Thanks.
