The learner will understand and be able to apply the common welding variables of the GMAW process.

In this animated object, learners examine an analog closed-loop feedback system that uses potentiometers to control the position of a gear rack.

In this interactive learning object, students view a basic wheelchair and identify its parts in a click and drag exercise.

In this interactive object, the learner reads an explanation of how various shielding gases are used in GMAW and FCAW. An exercise completes the activity.

Students view a video that shows the correct methods for starting a GTAW weld pool and adding filler. It focuses on the two problems that many students have – adding filler too soon and angling the torch so that the filler melts prematurely on the filler rod. Note: This activity is 3.6 mb.

Students view the operation of a process controls system and examine the components and their function to prepare to work with the actual system.

Review your understanding of fumes and particulates safety in welding.
