An experiment was made as regards the relation of the sectional area of the electrodes and the thickness of plates to arc welding current.<BR>The results are as follows : <BR>(1) The current increase or decrease is proportional to the sectional area of the electrodes.<BR>(2) And the current varies practically by <I>a</I> (<I>e</I><SUP>-<I>bx</I></SUP><SUB>1</SUB>-<I>e</I><SUP>-<I>bx</I></SUP><SUB>2</SUB>) where <I>x</I><SUB>1</SUB> and <I>x</I><SUB>2</SUB> are the thickness of the welded plates, <I>a</I> and <I>b</I> constant.<BR>From these two results, author has made a diagram which gives the suitable current in electric arc welding using any size of electrodes and plates.
