, B) electricity flows from the positive cathode to the negative anode.



C) electricity flows at random between the anode and cathode.



D) electricity stops flowing once the arc is established ANS >>> A



2. The SAW fluxes are ANS >>>



A) classified on their own. They have their own separate designation.



B) not classified. Only the wire is classified.



C) classified in conjunction with the welding wire forming an electrode/flux
designation.
