Where did the last name Lytle come from? Where did the last name Kerr come from?  English and Scottish: topographic name for someone who lived by  a patch of wet ground overgrown with brushwood, northern Middle  English kerr (Old Norse kjarr). A legendâ¦ grew up that  the Kerrs were left-handed, on theory that the name is derived from  Gaelic cearr 'wrong-handed', 'left-handed'.
Flux is the presence of a force field in a specified physical medium, or the flow of energy through a surface. In electronics, the term applies to any electrostatic field and any magnetic field.
A bare metal wire is used in conjunction with a separate flux. Flux is a granular composition of chemical and metallic materials that shields the arc. The actual point of metal fusion, and the arc, is submerged within the flux. (Process is also known as SAW, or Submerged Arc Welding.)
