Default Opinions on Victor SKH7A J series light duty torch for sheet metal work

I was looking for opinions on the Victor SKH7A light duty torch for sheet metal work. Any pros or cons when working with 18 or 20 gauge sheet metal and welding up to 1/4 steel? Looks like a variety of tips available

Good torch. AKA J27 / J28.
NOT J100 style, so tips will not fit.
AKA "aircraft torch" for welding thin sheet and tubing.
16, 18, 20 ga steel weld very well.
Widely used during WW2 for welding airplane 4130 chromoly tubing airframes.
And aluminum sheet.
And stainless.
And magnesium.

If I HAD to, I might could weld 1/4 inch steel plate with it, using largest tip I could find, and maybe with a hot plate under the part to help heat part,
but not on a cold day in a cold shop at 32F. For sure.
