I have one too, I like the idea of it but can't solder with it. For any serious work I use my old transformer iron that has enough power to melt the solder.
I've had a similar experience as a child. I live in Germany and found this voltage switch on a hair dryer. My thoughts were like: Switching it to less couldn't possibly hurt, could it? Well it could. It was super efficient though but only for a few seconds before it self destructed.
Current is not controlled here, resistance (aka the soldering iron) and voltage are.
Power = Voltage ^ 2 / Resistance. Double the voltage, that quadruples the power. So you only want to plug in 25% of the time to get the equivalent power of 120V.
But it might not melt at double power? Maybe the extra heat helps, I can't find a resistance/temperature curve for a soldering iron...
Ok. I was acountless on lemmy for a long time, your comment made me finally register. Thanks!
So, yeah, with double the voltage you get 4x the power.
But you you put 4 times the power at 50% of the time, you get only 2x the power. And the other half of the time, you get 0 power. On the average you get the same power output.
I had to think about it too, lol. This is an equation for DC/instantaneous power, and if you want to get into AC math, this is more like a square wave. Averaging the power out over time doesn’t necessarily work with the equation, as you figured out, as it doesn’t when you try to measure AC (sinusoidal) power by average voltage or whatever.
If my company fired people for trade show cock-ups we would change the entire staff every couple months. There is a lot of stuff being moved in a short time period, shit is stressfull and you're working at a diminished capacity at least a week aferwards. As long as the stand is not on fire during the show, all is good.
there's the STEM bell curve. XKCD shows the axes as 'how well your computer works' vs 'how well you know computers'. that is accurate.
but if you've ever known serious engineers who didn't just live boring white collar work-home-work-and-some-marvel-shit lives, you'll have seen things that make this look mild.
edit: and it gets really crazy when you're talking about a civil engineer. closest thing you'll ever find to an eldritch location.
I think there's another one, where the right side references operating systems, and another without the graph that's along similar lines. long runners sometimes return to the same wells, I guess.
New manufacturing hack unlocked: Install 240v outlets at workstations and fire half of the workforce. Golden parachute and douchey, hand-wavey TED Talk, please!
Yes, and they actually have a working thermostat, so they aren't complete garbage to solder electronics with.
Gas powered soldering irons are great for soldering stuff like copper water pipes. But even soldering through-hole components with them is a pain in the ass due to the temperature instantly evaporating all your flux. Soldering SMD components is near impossible with them
I like the pinecil, usb-c powered soldering iron with temperature control. If you are not doing anything intensive any fast smartphone charger will power it.
Afaik it is a safety thing that is handled differently in different countries.
Uk and their colonised countries have this. The reason is that the fuses are in each plug. But no (or almost no) fuses in the power grid of the house. In Europe most countries have a single GFCI and several fuses for power grid sectors in a single place in the house where the power comes in.
I assume the switches on the power outlets are for turning off a switch because there is no GFCI in the house.
I think in the UK at least this view might be a little outdated - every house I've ever lived in has had GFCI sectors across the house, or had to be updated to have it when work was done.
Reminds me of the time when I helped install some 120 VAC ceiling fans and the electrician* wired them to the 220 VAC line. They spun like a helicopter trying to take off.
*Worked for the local electric utility, we trusted him, foolishly.
I had the opposite problem, I brought a soldering iron from Europe to Canada, and despite using a step up transformer, it just couldn't get hot enough to melt the solder!
Seriously, many soldering irons don't have a switch. Fancy soldering stations have switches, temperature dials, etc. But basic ones are just a resistive load wired directly to the plug.
I've only seen outlet switches in the UK, unless you plugged into a roof lamp outlet where the switch are by the entrance door, but then you need a plug like these (at least here in sweden)
I'm an engineer that's been in that sort of situation. If it's planned, you have the tools. Unfortunately, sometimes these things happen and it's not planned. At that point it's taken what you can get. A cheap fire stick will still do the job better than no fire stick.
