Yes; I did decide to buy the auto darkening helmet that Lidl were offering, as I'd heard the supplied mask was pretty useless.
I got a few minutes this afternoon to get it going and have a try (hey, why not rush something you've never done before eh?). Anyway - I did suit & boot up, gloves, plus mask. Loaded the 0.9mm wire that came with the machine, put both dials at 12 o'clock (middle settings for wire feed speed and power), and had a go at laying down a bead on some 25x6mm mild steel bar:

OK, so I was moving too fast. Second attempt:

Not completely appalling.
I then grabbed an offcut of more 25x6 and tried to tack it on, then ran a fillet:

I went too fast for the middle section, and basically laid down nothing, so went over the whole lot again more slowly. The middle run of fillet isn't absolutely terrible I guess, but the start and finish are pretty ropey. It does appear to have held together though.
Having never even picked up a welder before I'm reasonably pleased; nowhere near as scary as I thought it would be, but I do now appreciate the level of skill required to balance the wire feed speed, power, travel speed, torch-to-workpiece distance, and rolling/circling motion to lay down a good bead.
I understand that this welder really isn't suited for anything over about 5mm, so having run it nowhere near full power I'm surprised it worked that well on 6mm material - but then I assume the weld probably won't have penetrated that far into the material.
But, a promising start. And plenty of pigeon sh*te splatter as promised
