Abstract	This paper presents the influence of the main parameters of the GMAW welding process on ingot iron sized 300 × 125 × 3 mm$^{3}$, with a 1 mm separation between edges and without any bevel preparation. Three gases were used in this research: CO$_{2}$, C15 and C25, with the purpose of studying the shielding influence of each of these gases separately in the welding process. In this research different power ranges were used with the purpose to assure the quality of the surface finish on the bead and the minimum penetration on the plates. The influence of the welding torch’s direction of advancement (forehand or backhand) for positions PA, PC and PE were studied together with its influence on the power source. The position which needed the least energy was the PA, followed by position PC and then position PE. The forehand advancement direction required more power than the backhand advancement direction for all positions. The influence of the gases from high to low on the width of the root bead and face bead was C15, CO$_{2}$ and C25. This work would be useful to evaluate the influence of the welding parameters on a welding procedure specification with the GMAW welding process.
