WebAug 4, 2024 · What Is Stick Welding. Shielded metal arc welding (SMAW), also known as manual metal arc welding (MMAW or MMA) is a welding process that uses a flux-coated electrode to join metals. An arc forms when the electrode tip comes into contact with the workpiece. Fusion takes place as both the rod and workpiece melt, forming a weld pool … WebVoltage varies as a result of changes in arc length. With CC output, current is your preset, controlling variable and voltage is simply measured (typically as an average value) while welding. If you tried to weld with the SMAW process for example using CV output, current, and the resulting melt-off rate, would vary too much.

WebCV welding. For SMAW on CC sys-tems, however, the arc voltage is determined by the arc length, which is manipulated by the welder. As arc lengths are increased with SMAW, the arc voltage will increase, and the amperage will decrease. Arc voltage also controls the width of the weld bead, with higher voltages generat-ing wider beads. Arc voltage ... Shielded metal arc welding equipment typically consists of a constant current welding power supply and an electrode, with an electrode holder, a ground clamp, and welding cables (also known as welding leads) connecting the two. The power supply used in SMAW has constant current output, ensuring that the current (and thus the heat) remains relatively constant, even if the arc distanc…
