Dust and dirt need to be periodically removed from the following parts of a welding power source?

Ohms Law states: , where R=resistance, I= the current through a conductor and V=voltage.

A given static load on a weldment will not cause failure of the weld.

The presence of dust and dirt within the spark gap will the voltage required to jump the gap.
