This course introduces students to computer-assisted drafting techniques used in electronics. Students will learn the basics of AutoCAD, including drawing, editing, settings, plotting, dimensioning and layering. Laboratory time will be used to practice these techniques and apply them to electronic pictorial diagrams, schematics, printed circuit board track, layouts and technical literature illustrations. This course covers the basic principles of AC and DC circuits. These principles are used to study the operation of electric arc welding equipment.
Emphasis also is placed on the troubleshooting of commercial arc welding equipment.
The student will participate in classroom and laboratory exercises in the study of the basic concepts and laws of alternating and direct current circuits. The course will include the study of Ohm's law, and half, full wave and bridge rectifier currents. The effects of high and low frequencies will be studied in relationship to welding practice. This introductory course explores the use of common tools for constructing electronic devices. The safe use and applications of hand tools and power tools are stressed through the construction of projects.
