The 120l/m versions will not enter in stand by mode once put in stand too?
Yes they do (stand has magnets in it).
They just don't go as high on airflow, which isn't an issue IME (low airflow for components, higher airflow for heat shrink or softening stickers type of stuff). So I don't seen any need to go for the higher powered models (1.2kW or 1.3kW versions at a LOT more money), unless you're working on boards with many layers that use large power & ground planes.
Even then, you'd be able to get an 861Dx + an inexpensive preheater for less than the more powerful brethren anyway and have the same capabilities (or
very similar if there's a short-coming due to the 1kW rating of the 861 models).
Regarding working under a microscope, see previous post.
BTW, JBC makes such things readily available. And although they're not horribly priced for what they are, they're not inexpensive either. Much less expensive to DIY your own (rivets are a quick, easy, and inexpensive way to attach the two ends together).
...[snip]...i use a IR bottom heater at 160ºc, without a nozzle the airflow is barely noticeable at 23l/m, thats why i'm thinking get DA or DE, in this case 200l/m. But i don't need the 200l for sure.
Agreed.
FWIW, my unit appears to have the same handle (and presumably heating element) as the larger 1.2kW & 1.3kW versions. Definitely some time passed between your and my units manufacture dates. The sticker on the rear states it's a 1kW station. And though I've not tested this to be certain, I've not found the need to purchase a Kill-A-Watt to confirm this, as it's handled everything I've thrown at it (with or without preheating).
Regarding preheating, I tend to err on the side of caution though. So if I even remotely think the board could warp or the station can't handle it, I set it over my cheap-o preheater first (I figure
"why not, I have one" mentality
).
Why Angled nozzles are ridiculous?
For what i have understand nozzles are all compatible except for DA verson right?
Angled nozzles aren't ridiculous at all IMHO. Just not absolutely necessary, even when working under a microscope (see above). Just use the microscope for inspection after drag soldering.
If you're absolutely dead-set on using hot air under a microscope however, the angled nozzles will make things easier, shields or not (DIY or purchased). Regarding blowing parts out of alignment/off the board, the trick is to reduce the airflow; magnification or not. You don't need high airflow settings to melt the solder (actually the lower the airflow, the closer the air is to the set temp as a general rule). So I find higher airflow is only useful for heatshrink tubing and removing stickers (you'll warp plastic/remove paint if it's set too hot
).
861DE (200l/m) has the same nozzles as 120l/m versions. Seems that particularly DA has thicker heater and different nozzles.
From what I've seen, there's no difference other than input voltages and plugs regarding the 861 models from what's currently being manufactured.
wraper's Quick 861 has a different handle, and presumably a different heating element than mine as well (his looks the same as that used on the 957D for example). While mine has the same handle as the more expensive 855 & 856 models (these use an element cartridge that includes the stainless steel outer tube). Found the 220/230/240V replacement element for these on aliexpress for $63.
That said, do keep in mind his has served him well (and is continuing to do so).
So regardless of the particulars of the handle (NOS or right off the assy. line), it will perform well.
What are the WD DW and DS differences? Only the plug?
IME, the DW version is for the US market (110V input = different transformer + different heating element). While the DA or DS models only vary in regard to the plug (both = 220V input).
