TS100 doesn't function properly when earthed

[TheBay]

I bought a TS100 because it was on offer, I paid £30 for the "Brown" upgrade version with a couple of tips.
Handy for portable use etc and can use on a home made battery pack.

It's a great iron, however I think some are missing the point with this iron, paying £50 or more for it then another £50+ on power supplies and things,
this no longer becomes good value for money and the money would be better invested in a soldering station instead, especially if it's used just on the bench.
And then there is taking in to consideration the intricacies of its quirks regarding grounding.

You are right. Silly of me suggesting a $50 power supply!

I don't understand something about the conclusions in this thread. It is suggested that all is well if a properly grounded DC supply has its negative connected to the ground of the device.

OK so far. Now, I wonder, wouldn't be all OK if one directly grounded the negative and the device manually? (I mean even if the PSU is cheap and non-grounded initially)

Hello, I am contemplating buying TS100. I currently have a 3 prong laptop PSU, is it safe to use with the TS100 providing ground? Sorry newby question...

For those considering power bricks:

MeanWell GST series does not have -ve DC output connected to earth ground and should be avoided for the TS100.

The medical grade GSM B series is only 2 pin so do not get that either.

However the medical grade GSM A series does have -ve DC connected to earth ground, so that is good.

I think the MeanWell GSM90A24-P1M should be good.
