A welder should know the meaning of polarity, and recognize what effect it has on the welding process. With few exceptions, electrode-positive (reversed polarity) results in deeper penetration. Electrode-negative (straight polarity) results in faster melt-off of the electrode and, therefore, faster deposition rate.
