I managed to run my thermal arc 175 on 300' of extension leads, I had to turn it up to 150 amps on the dial to get it to behave like it normally when set to 110 amps
Can't help with a copy of the English instructions but If you have the Google lens app you can take a pic of the French instructions and it'll translate them for you.
On the subject of ways to die, Has anyone seen the Russian lathe accident video? The one where he's turned to red mist, I won't post the video but it's gruesome.
I had a LED floodlight stop working due to water leaking into it and the sparky who was changing it noticed it felt hot so he switched the power back on and stuck an amp meter on it and it was drawing about 4 times the power than it should draw when working normally.
I'd imagine any sort of breeze or draft is going to cause problems at that low flow rate. I normally try and make sure there's a reasonable draft when I'm welding.
Here's a pipe set I removed from a car with a failed turbo. Someone had covered the gasket in sealer and almost completely blocked the oil feed to the turbo
Should be this gasket on that engine

What kind of arc length are you using, I had similar experience with contamination like that when I was learning from letting my arc length get too long while moving along.
I've used normal 14mm mild steel rod as a handle on one of my vices, I probably could bend it if I wanted to but I wouldn't put my vice under that kind of pressure. I'd also be afraid of what would happen to me if something broke while swinging out of it that hard.
I was drilling some 40mm thick mild steel plate and hit a spot where it seemed to be a lot harder, all of the sudden the drill bit just flew about 10mm into the plate accompanied by a puff of black dust out of the hole. There was some sort of inclusion in the steel but I don't know what it was.
