Good eye sight or glasses to magnify, I have prescription lens just for welding they have the reading part for the whole lens , not normal bifocal.
I Also use a cheater lens in the helmet ( cheap couple bucks at weld shop)

Good fit up is your friend!!!!!!! I like to have no more than .015 gap

Start out just running a puddle on a scribed line, no filler.

Cut a one foot square of 18 ga. Scribe lines 1 inch apart, When you can run the puddle and keep a consistent bead width for a foot long weld on all scribe lines, then make a a new square and do the same but now add filler.

Since the sheet is thin the puddle goes almost through, so very little filler is needed, the filler is more than half the thickness of the sheet.

Bead width about 1/8 th to 3/16 inches. Not an even ripple pattern just dab about every 3/8 to 1/2 inch.

A tall bead is no needed and will need to be ground off later!

I do the same with the glasses, My trig-focals don't work. Magnifiers too. Now I'm trying bicycle headlights to light things up a bit.
