content: Does anyone know of a source for the heater part of the Hakko 707 desoldering gun??Or is there something that can be used instead of the original part? Perhaps another Hakko heater???Wally

content: ...but maybe a few hours digging deephttps://www.aliexpress.com/item/32979065317.htmlmight give you something to try. I have no clue if that item works but it might be the start of a trail that leads you to a compatible part? I used the search terms "ceramic desoldering heater".

content: Thanks for the repliesAlex's suggestion might actually work, it is about the correct wattageThe 707 does not have temp sensor...not a big dealWill investigate further.Drawings with dimensions might be helpful, don't see any dimensions on the Hakko manual drawings either.However dimensions can't be too far off...or could they?At this price might be worth a try.https://www.manualslib.com/manual/1186329/Hakko-Electronics-707.html?page=7#manual

content: Rather than kludge in a different heater, I think it might make more sense to replace the whole gun with a ZD/Pro'sKit/Yihua gun.But then I would ask if your Hakko vacuum pump is working well enough to make that worthwhile, since that is a real weak spot in the 707.

content: Sure, the 707 is pushing middle age now, it's been around for what, 40+ years?I guess anyone still using one is not using it for commercial production... I assume it's a hobby tool now.Guess it depends how much energy,time, and money he wants to put into it. At some point a modern tool makes more sense.As for the pump, the flapper valve thingy turns into a buttery substance and it fails. I have made a few from a silicone kitchen mat. Works well enough. I'm not reaching the same vacuum as the datasheet says but my Commodore 64 can't tell the difference...Here's a PDF I made of the dimensions I usedhttps://drive.google.com/file/d/1mpJc4Xyw8l8JnnZhL2fQx4KkgRQubvAt/view?usp=sharingSorry about the colors and line widths.edit: I suppose I could mail one out, PM me.

content: How different is the 707's heater with the next generation A1008 used in the 470's (802 gun)?Dumpster rescue of a Hakko 470, needed a new heater A1008 or A1029 which are discontinued. Instead, I did the heater retrofit (conversion from 802 to 809 gun) to A1313 heater. So you need a new sleeve, nut, tips, and seal for the conversion. Pics below for ideas etc.The A1313 heater (which is a generation after the A1008) they increased wattage, bigger diameter and added the longer tube. The 470's controller board looks at heating element resistance for temperature sensing, there is no dedicated temp sensor.What I find is the base is not worth that much, despite having the monster vacuum pump. It's the guns that get dropped and broken and are worth almost all of the money. Many surplus 470's for sale... but missing wand. I thought there were Hakko gun knockoffs though on Aliexpress under"Yihua 948"but you'd have to change the controller to use them, they are 4 wire heaters. Or look atProskit.Hakko A1014 Valve Plate fits many models FM-204, FR-400/410, 470, 470B, 472D, 474, 484, 701, 702, 702B, 703B. You can still buy them.

content: I know there's a Hakko valve plate that looks just like the 707's but it's like half the size and thickness of what's needed.

content: Quote from: floobydust on May 17, 2022, 07:13:40 pmThat is much smaller than the 707's valve plate. There was someone in a previous thread who claimed he got it to work in a 707, but I don't understand exactly how:https://www.eevblog.com/forum/reviews/help-with-hakko-707-desoldering-make-my-own-valve-plate/msg284696/#msg284696

content: Here's a baffling findhttps://www.aliexpress.com/item/1005002540648888.htmlI have no idea what these are used for. Maybe these come in different lengths.

content: Resurrecting an old thread, but I'm also on the hunt for a Hakko (or anything that will fit) heater element for the 700 and 483 desoldering stations.I have recovered two of these from my old employer, they were being dumped (probably for good reason) and both the guns have dead heating elements.Wally, did the AliExpress element above work? (If you tried it)Happy to try anything that will physically fit and kludge the rest.

content: I'm now in a similar situation. Has anyone been able to source a replacement heating element for the HAKKO 802 de-soldering gun? I converted one of my stations to the 809 heater and other necessary components, but continue my quest to find a replacement or workaround for the HAKKO A1029 element used in the 802 gun.

content: Reopening topic here. What's the voltage supplied to the heating element. I don't have the station in my possession as I am considering buying one without a gun from a local repair shop. I did get to look at the inside briefly and it doesn't have a transformer. Could it be powered by mains voltage? The manual only species a 60W heater.

content: I wouldn't buy a 707 these days. There are so many other options that don't require a time machine or endless guesswork to get working. Plus all the consumables.And where are you planning on getting a gun?Page 17 of the manual shows a diagram and there's only a board between the mains and the heater. A light dimmer, essentially.Also make sure you're not getting a Venturi pump version. IDK if they made the 707 in shop air but who knows.
