I did a lot of welding outside using flux core wire (NR211) and my IGBT welder, worked a treat.

For me personally I wouldn't go back to using gas (Argoshield etc).

It does need to be reverse polarity for flux core wire.

Welding gases are all inert - non flammable.

So no need to worry about where it's stored. The only issue can be breakage of the gauge if it topples over but that's about it.

My acetylene welding gas is REMARKABLY inflammable but I know what you mean, all welding shielding gases are inert!

Kind of....
Alot of gas mixes have a small percentage of oxygen making it active, (mag) rather than mig.

I think they all have less oxygen then the surrounding air though?

So in the event of a fire, you would be better off opening the bottle in the shed rather than dragging it away from the flames!

I'd be dragging it away because it was too damn expensive to lose!

I remember there being concerns over a bottle that had leak down completely over night in the workshop the contents of which had gone into the pit ?

Yea, Argon and c02 are heavy and will sink.
I expect a normal size welding bottle could fill an inspection pit easily enough.
You'll probably notice if it's c02 but might not be able to get out.

Argon, not so much chance of escape.
It's a high-end slaughter house gas. Used because the animals don't realise they are dying...

I'm talking from a technical standpoint, that the shielding gas can be classified as active with the addition of oxygen and other gasses,
Not that anything is flammable thus making a mig welder a flamethrower

did you pick that up from a old farm barn property in shropshire by any chance?

it looks familiar. deceased owner?

i might be wrong but the scratches on the case look like a old friends machine.

It was from Stoke way, I guess if it is its changed hands a couple of times till me. Do you have any pictures of your friends machine?

Unfortunately not,
