Electrical Power for Arc Welding 241
Electrical Power for Arc Welding explains the basic principles of electricity and the effect that electricity has on arc welding processes. Electricity travels in closed circuits. A basic circuit consists of a source, path, load, and control. Current is the flow of electricity. Voltage is the force that pushes current through a circuit. Resistance opposes current flow, but also makes it possible for electricity to perform work. Electrical work is called wattage. In welding circuits, the resistance of the arc converts electricity into light and heat, which melts the base metals.
After taking this class, users will have a foundational understanding of electricity, electrical variables, and how electricity is used in arc welding. This will prepare users for welding, since every welder must understand basic electrical concepts to work with the arc and the welding equipment that produces the arc.
