If you want clean, strong welds, it starts with understanding the process properly and how your MIG welder makes that happen.
MIG welding is often seen as the easiest process to learn, but motorsport fabrication places very different demands on the technique. In this module from the HPA Practical MIG Welding Course, we cover how a MIG welder actually works, why shielding gas matters, where flux core wire fits in, and how the automatic wire feed creates the molten weld pool.
Understanding these fundamentals gives you the foundation to produce stronger, cleaner welds and avoid the common mistakes that hold beginners back. If you're planning to weld a roll cage, modify a chassis, or work on critical motorsport components, this course builds the skills you need.
