What does DC+ stand for in FCAW-GS terminology?

• A. Direct Current Electrode Positive (DC+)
• B. Direct Current Electrode Negative (DC-)
• C. Alternating Current (AC)
• D. Direct Current with Ground

Answer: (A)

Direct Current Electrode Positive means the electrode is the positive terminal, so the current flows from the electrode into the workpiece. This polarity concentrates heat at the electrode and its flux coating, which helps melt the filler wire and keeps the arc stable in gas-shielded flux-cored welding. In FCAW-GS, using DC+ is commonly chosen because it promotes consistent metal deposition and a smooth bead, especially on ferrous materials and when reliable metal transfer is desired. If you used the opposite polarity, more heat would go into the base metal, altering penetration and bead shape; alternating current wouldn’t provide a fixed polarity, and grounding isn’t a polarity setting in this context.
