Arc or Mig?

Colin Furze does it on his tunnel and bunker build.

Along with all those videos of no helmet welding in Pakistan.....

I welded it with 6013's - as I managed to beg/borrow enough mat and rebar for the job - plus I did not have any tying wire

For your application 6013s should be absolutely fine.

It's not as if it's a road bridge that's cyclically loaded.

Nothing beats the safety squint

Gotta watch it with rebar, if it's from china it's got assorts of other stuff in it that doesn't like being welded to qualify as a alloy (cheaper to import).

If the bolts in cones are preset in the concrete, you will need to get all the feet on in exactly the right orientation on each upright, or laying out will be a pain.
Id mig it too, as its quicker, but a stick would work just as well.

Bolts are not preset. Pour 400mm concrete, bolt uprights to concrete, pour another 700mm of concrete. Total amount of concrete is 1.1m3 per upright. (6 uprights in total)

These are what steel framed buildings are normally put up with. The footings are poured to to a level, and bolts preset in the concrete. The cone allows for a bit of wiggle. A ply wood model of the foot is used for laying out. Once set the shed is assembled, then levels checked and steel shims used under the feet to get level spot on. The feet are then concreted in when the floor is poured.

As much as I enjoy his antics, and he is getting results...

I am not 100% I would use anyone who thinks "you know, maybe, just maybe I should consult an engineer about this project" only after he's under-mined one side of the house he lives in with his wife and kids as a reference on good practice.

But then, the back did fall of my parents house as a kid, maybe I'm just sensitive about such things and unfairly judging him.

A lot of his antics are just for show. Scratch under the surface and you have a good engineer and fabricator who really knows his stuff. I am, sure a lot of planning and design went into this behind the scenes!
