Robotic welding allows welders to create more consistent and higher quality welds. But, it requires you to understand the terminology associated with its programs. Watch this module to review terminology associated with robotic arc welding and the weaving process.

In this animated object, learners examine the design of a ladder circuit that provides manual control to a water pumping system. Students also study modifications to the circuit as the complexity of the system increases.

In this animated activity, learners examine how a voltage is induced into a conductor when the conductor cuts across magnetic flux lines. They also view the four factors that determine how much voltage is generated. A brief quiz completes the learning object.

Learners examine the counter-reset function of a programmable controller and how it is used.
