Spot Welds
You don't need the machine, but it's nice. The alternative is a series of holes, cleco size, about 3/16" drilled or punched in the fender skin. Harbor Freight has a flanging/punch that does a great job at a reasonable price, but you may be able to rent one - maybe even better. Install the holes about 1" apart, clamp and start skip welding filling each hole as you go along. This also works for welding the other seams on the panel.
Keep the metal cool by blowing cold air on the welds. You should be able to put an ungloved hand on the surface and it not be as hot as a cup of coffee. That's my son putting his son to work.
Primer & high build
painted - both sides were done the same way
