Abstract
As the supplemental work to the previous paper, the electromagnetic force, which is included in the measured arc force, is estimated by some experiments and considerations. Then the measu-rements of arc force in MIG arc with Al, Cu and stainless steel electrodes are described. (Figs. 6, 7, 8). The results are discussed in relation to those given by other investigators. Some consideration is also made on the nature of arc force.
