Polarity results from the fact that an electrical circuit has a negative and a positive pole. Direct current (DC) flows in one direction, resulting in a constant polarity. Alternating current (AC) flows half the time in one direction and half the time in the other, changing its polarity 120 times per second with 60-hertz current. A welder

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.

Differences Between Welding Brazing and Soldering - …

The differences between welding, brazing and soldering are 1) the type of materials being joined 2) the types of filler materials used 3) the appliion and process tolerances 4) the amount of heat applied to the base materials .
