In several of the welding books I have it says you need to insulate

With O/A-welding, that's sometimes right. Only when I was trained at, we
had a kind of grating. just several upright flat irons, distanced about
1" apart and welded in a frame.
Looks like your first project? :-)

Later, I never needed something like this.
