Stick Welding Tips, and a Few Techniques, Do''s and …

Stick Welding Dc Positive or Negative: If the goal is to achieve the deepest and high penetration, then the DC Positive or the reverse polarity should be used for stick welding. In this process, the electrodes attached to the positive pole and workpiece attached to the negative pole produce much heat with the high velocity to weld into the metal for a deeper penetration level.
