Last thing I welded was a stand to hold a stainless steel sink
(which was used to mount a new garbage disposal to grind apples
for making hard cider).
I used one of those corner magnets to hold my 1' square tubing in
place, and I also noticed that it had a pretty liberal idea of
"square". So after the first few I figured out that I should
check them with a real square (a 2'x2' carpenter square),
tack them into place, and then check again after doing the tack
weld to be sure that I hadn't moved the work during welding.
I had a couple joints that were too far out of square or poorly
aligned, so I beat on 'em to break the tack weld and did 'em
over.
Once I had it all tacked together with square-enough joints
I checked the fit of the sink and welded it all up.
