content: Okay, so I am aware that this has been talked about about and it had been made clear that if you do want to use a US model here in Australia, you need to use a step down transformer.Still for months now, I have not been able to let this go, you know there must be a way.Now I should point that I am not someone who really know all that much and I probably have it very wrong, but...Now I have access to a hakko 808 gun, and I can say that it dose not have a transformer, the only place where one could be houses the pump. So how on earth dose it work, well I think and this is me, that the heating element runs at 240v like a cheap soldering iron. Along with the pump its self also runs at 240v.With that in mind, I looked up Google and found the manual, very easily.So I have this for you to look over:Heating Elements:A1228 - 100v/50wA1233 - 110v/50wA1234 - 120v/50wA1235 - 220v/50wA1236 - 230v/50wA1237 - 240v/50wPump esse:B1729 100-120vB1835 220v/50HzB1836 230v/50HzB1837 240v/50HzB1838 220v/60HzTemp Contro:B1738 100-120vB1814 220-230vB1815 240vP.W.B Motor:B1744 100vB1808 110vB1809 120vB1811 220-230v/50HzB1812 220v/60HzB1813 240v-50HzMotor with Capacitor:B1737 100-120vB1831 220v/50HzB1832 230v-50HzB1833 240v/50HzB1834 220v/60Hzhttp://www.jameco.com/Jameco/Products/ProdDS/568173UsersManual.pdfNow, after I had gone over all of this, it comes down too a few options, spend about the same as a local hakko 808 or more importing and then swopping out the electrical parts, but then its pretty much a waste anyway, since you might damage the desoldering gun.Unless you can pick up a hugely cheap one, say $100-$150 AUD including shipping, its possibly not worth itSo buying one local would end up being better anyway, or look at buying the cheap knock off desoldering gun, the S-993A, just Google it.Anyway, let me know how wrong I am.

content: Not entirely sure what you're after, but as I see it, you have two basic options.1. Buy something made for your mains voltage (whatever make and model; new or used).2. Use a stepdown transformer with the Hakko 808.

content: 120V autotransformers are cheap.It's only 70W and isn't continuous duty so you could probably get away with a wall wart sized 240V to 120V adaptor.

Would this cause any issues?

content: 120V, 110V all are in the allowed range for the devices. Not a problem at all.

content: Quote from: SeanB on December 26, 2013, 07:29:13 amThe other thing is, someone said this was a 75w device, yet it was listed as a 50w device. It sound like it might be worth spending the extra $10 and get a step-up transformer which is 200w, then just getting the 100w, which was one of the things I was thinking about. The other is just wasted the money and spending $500 for one, but then I do not get the kit that goes along with it.

content: The manual said it's 70W and the element isn't powered continuously so 100VA and 110V should be fine.http://www.tortech.com.au/step-down-transformer-australia/new-range-usa/100w-economy-step-down-transformer-240v-to-110v-converter

content: Dont get the s-993, or the variants. The motor is not built right. It may be built for msx 220vac, china mains. The pump motor could not last on 240vac 60Hz mains.
