nice tool - and good score with that weird unbrella mount.
What is the conductive path to the workpiece when showing the TIG welding at the end of the clip?

Thank you. There's a small set back, the magnet is not completely flush with the base. Which allows the base to make contact with the table and create a conductive path. Thank you again. hope this makes sense. ��
