In this study, the heat source characteristics of arc plasma in GMAW using 100% CO2 shielding gas. In particular, arc temperature, Fe vapor concentration and electrical conductivity and metal droplet temperature of a YGW11 wire electrode were measured by optical emission spectroscopic methods. The plasma temperature reached over 8000 K at the center of the arc plasma. The droplet temperature near the arc root was higher than other areas.
