Advanced VFD and Electrical Controls Training for Third-Year Service Apprentices
Our third-year Sheet Metal Service Apprentices are strengthening their electrical and HVAC controls knowledge through advanced, hands-on Variable Frequency Drive (VFD) training.
During this exercise, apprentices wired a momentary push-button switch into a holding circuit used to start and maintain operation of a VFD. They then configured the control sequence so that once the drive reached its commanded speed, an output signal energized a 120-volt indicator light. This provided a clear visual confirmation that the system had achieved the intended operating condition.
The project challenged apprentices to apply electrical theory while developing practical skills in control-circuit wiring, VFD operation, relay logic, sequence of operation, electrical schematics, and system troubleshooting. Students also practiced safe testing procedures and verified each stage of the circuit before placing the system into operation.
By combining modern HVAC technology with realistic troubleshooting scenarios, our apprenticeship program prepares students to confidently install, service, and diagnose today’s increasingly sophisticated building systems. This productive training develops the technical ability, problem-solving skills, and attention to detail required of highly qualified service professionals.
Precision in Practice: Third-Year Apprentices Master Press Brake Operations
Our third-year Sheet Metal Apprentices are advancing their fabrication skills through hands-on training with the press brake—an essential piece of equipment used to form precise bends in sheet metal.
Under instructor supervision, apprentices practice safe machine setup, proper tooling selection, blueprint interpretation, accurate measurement, and bend sequencing. Every exercise reinforces critical safety procedures, including personal protective equipment, machine guarding, pinch-point awareness, and proper material handling.
This advanced training combines classroom knowledge with real-world fabrication techniques, helping apprentices produce accurate, high-quality components efficiently. By learning to work safely and productively with industry-standard equipment, our apprentices are developing the technical skills, confidence, and craftsmanship required to succeed in today’s sheet metal industry.
Safety, precision, and productivity aren’t just lessons—they’re the foundation of a highly skilled workforce.
