1968 Barracuda Notch 340

Here's a tip: my eyes are 60 years old so they don't dilate as quickly. Here's a sequence of what is happening with this type of sheet metal spot welding with an auto lens ( highly recommend):
1. Ready to weld, protective lens is automatically off. Work is lit via shop light. ( though too much light and the auto shield will engage)
2. Weld arc contracts pupils, even after lens automatically shields vision. Even with lens on full, my eyes are still like " oh ****" and im semi blinded.
3. Arc terminates, auto lens instantly off, pupils begin to open and my next step here in this instant is to " see" the red glow of the spot weld to ensure the next spot welds' placement is on the joint. This instantaneous step used to be no problem but has changed with age, now Ive found a way to squint/train my focus during an arc, to better see the glowing weld in between arcs.

This enables a pace. Pace is important even if im doing 3 or 6 spot welds at a time because that first spot weld is colder and usually clunky, the next 2 or 6 in succession are always laying better, on point, and over the joint because I'm tracking the placement in between arcs and making tiny adjustments based on the vision of the glowing weld after an arc . If I did one spot weld at a time stopping in between, the placement is never as good and its chunkier because it's colder which generates more gaps and more grinding. For me, the first welds placement always has a certain amount of guess work. There's a half inch nozzle in the way and somewhere a tiny wire will show itself. Tracking this via " glow" in between arcs really works well for me.
