Learn to weld in one episode! Tucker and Travis teach their friend Taylor the fundamentals of flux core welding while repairing a trailer with the portable Lincoln 90i FC. We cover PPE, surface prep, machine setup, dialing voltage, and beginner bead techniques (circles, half moons, zigzags)—then put it all to work in the field. In this hands-on tutorial, you’ll see:• What welding is and why it’s so useful for real repairs (farm, ranch, trailer, and shop). • How the Lincoln 90i FC works (gasless flux core, wire feed, ground clamp) and how to load the wire. • Essential PPE: auto darkening helmets, FR welding jackets, gloves, face shields for grinding. • Surface prep (grind out old welds, remove spatter) and attaching a solid ground. • Settings & technique: voltage = heat, test beads, watch the puddle, control with small motions. • Field practicality: runs on a standard 120V outlet and flux core is less sensitive to wind.
