Soldering is a time-tested method for creating durable, conductive electrical joins — but only when carried out correctly. Poor soldering practices can lead to weak connections, cold joints, or even safety hazards. That’s why understanding solder composition, flux, tools, and proper insulation techniques is essential for technicians who want to deliver safe, professional repairs.
In the latest addition to our training course on Wiring Harness Fundamentals, you’ll explore the different solder types, leaded vs. lead-free alloys, and the role of flux in achieving clean and reliable joins. This module also covers soldering irons, tips, and supporting tools like heat sinks and desoldering equipment. By the end, you’ll have a solid foundation for making repeatable, high-quality solder joints in automotive applications.
This module will be the latest addition to our growing library of over 390 technical training videos, covering the following key areas:
