About this document
Welding Power Characteristics Explained by Hazim Hamdan is a document available to read on EtoBox.
Constant current welding has better arc stability but is more sensitive to voltage variations. It is suitable for manual welding. Constant voltage welding can maintain a consistent arc length but the wire feed speed must continually adjust to maintain current. Constant voltage is less suitable for methods that typically operate at lower voltages. The magnetic pinch effect occurs due to the magnetic field at the electrode tip constricting the electrical flow. It allows for cleaner metal transfer in GMAW. T
