I'm interested in a TS100 soldering iron as a decent starter iron and a light one that doesn't take up too much space. It doesn't come with a power supply though, presumably to keep it flexible as it can take 12-24V input (max 65W usage). So I found this 24V power supply to go with it.
Here's the power supply purchased separately:
My question is whether this device is grounded and if so how, or if not, is it safe to use or does it risk shorting out into the user? I would think it is not grounded since most AC/DC adapter barrel connector power supplies I find are only 2-prong (is it necessarily only 2-prong). In that case, I'd hope the device is insulated - how would one check that?
The closest thing I could find to a spec sheet for this iron is here: https://imgmgr.banggood.com/images/upload/2015/11/TS100/TS100%20Soldering%20Iron%20Instruction%20Manual.pdf It mentions a ground screw and connecting a ground wire to that. Does that imply that for safe use of the device, I'd need to - in addition to the power supply - have a ground wire clipped under that screw and connected on the other end to a reliable ground like copper plumbing pipes?
