4 Electricity will always follow the path of least resistance to ground. WHY SHOULD WE GROUND?Electricity will always follow thepath of least resistance to ground.Proper circuit grounding will keep electricity from using your body to get to groundGrounded Circuit Requirements:Path is continuous and permanentAmple capacityLow ResistanceCircuit parts are bonded together
5 WHAT DO WE GAIN?Provides personnel safety - #1 priorityProvides a stable signal reference for instrument accuracyControls Radio Frequency emissions & Electromagnetic Interferences (EMI’s)Provides a discharge path for short circuits and lightning strikes

33 BURNDYWELD USES AN EXOTHERMIC PROCESS TO JOIN COPPER PROVIDES A SOLID COPPER IRREVERSIBLE BONDWILL NOT LOOSEN OR CORRODE AT THE WELD
34 EXOTHERMIC PROCESSThe exothermic process is a simple, efficient method of welding copper to copper or copper to steel.This process uses a high temperature reaction of powdered copper oxide and aluminum.Reaction takes place in a graphite mold.Mold will last for 50 or more welds with proper care.This system is very field friendly, since it is light and portable and requires no outside power.
35 THE SEQUENCE OF STEPSOpen mold using handle clamp, and insert the conductors as desiredInsert steel disc into the mold cavityPour powdered metal into the mold cavityClose the lidTap powder container to add the starting powder to ignition pocketUse flint device to igniteBrush and remove moldMOLD
