RMA stands for "Rosin Mildly Activated". No clean stands for, well, no cleaning required. In the red it specifies what each is good for.

The only differences I see with the RMA variant are:
-Needs to be cleaned as it's more tacky and prone to corrosion if not cleaned up.
-The "solids content" is higher at 18% rather than 4% with the no clean variant.
-It's suitable for manual tinning to restore solderabilty.

I guess you get what you pay for right ?
This is the 998D soldering station i just unboxed.
And im so glad i checked , the earth was not even attached in the hot air gun,
and was not even soldered or crimped it was just placed between the metal and the casing to try make contact, im guessing that's why there was wire pieces there..
Main case of unit not earthed, but outta part of transformer is. the soldering iron seems to be ok tho, and the iron is earthed..
Got a bit of confusion with fuse tho, in the pic its brown which is live that appears to go direct into fuse, center piece, but when i connect multi meter for continuity on live of plug to fuse it beeps out, but if i connect to neutral of plug and outta of fuse holder it gives me a reading of, .087 on continuity is this right ??
Also as you can see they love a bit of Hot glue
And was also wondering why that transistor also did not have a heatsink ?
If you could talk a look guys and tell me whats up/what the deal is that be great thanks

They have earthed the laminations on the transformer. They should have centre-tapped it to earth. That way, in case of a fault, you only get 115v RMS AC instead of 230v.
You may find that the earth may not be connected due to earth leakage tripping RCDs. Pretty dangerous though if you don't have RCDs in your consumer unit.
Them Chinese eh?
Try one of those death-daptors they throw in to adapt euro 2 pin to BS1363 UK. You can plug the earth pin into the live, resulting in the whole appliance becoming live!
RCDs ??
how should it be earthed i dont wanna turn it on now :S
Simple sketch or something be great budd,
Unit is still open waiting for advice so
EDIT Oh rcd your talking about the trip plugs
Last edited by Canna,
The trip plugs are MCBs... Circuit breakers. RCDs break connection in case of an earth fault only
That earth Crimp goes to the laminations and one to solder iron and one into hotair which i repaired earlier,Should i earth From the crimp or the other post on the lamination to the case, shell ?...
How should this be earthed,
And know our main circuit breaker in house is fuse only..Ya know the four prongs with the fuse wire between.
Im either thick as shit or im still unclear what to do to this unit
https://www.screwfix.com/p/masterplug-rcd-adaptor/63731 that no good then ?
You need the lowest impedance path to earth.
So, a good earth wire (we call them CPC in trade. Not in trade any more though! But can`t imagine much has changed since I packed up) from the metal on the nozzle (however you attach it) to the earthed point on the transformer laminations. So you have a good connection (put both ring terminals on there) The housing looks plastic and the switches look plstic, so this is classed as double-insulated. So no need to earth that. Anything metal that you can see, that you can touch, should be earthed. And check its earthed with a multimeter at least, in the absence of an Earth fault loop impedance test with a proper low-impedance tester like a Megger or a Metrel or something. Over the top? Maybe. But you can`t trust that device at all until it is earthed.

Crap man. I wanna pick your brain! College educated? Or self taught? I'd love to learn about rework stations. I've soldered for many years. Just high school classes. Can you recommend a good learning path for a 41 year old?
Practice practice practice.
No college in the world will get you experience.
Get old boards. Any old boards and practice. Reflow / remove ICs anything.
We will get you swapping TSOP48s in no time
Its what i thought thanks budd.. i was going to ground/earth the case anyway, which is metal btw. You just threw me when you said about the lamination. rcd and mcb..
Both ring terminals ? you mean on each end of ground wire or are you talking about grounding the other post on the t******...<
.Thank you for the reply, il ground this out and if you dont hear from me after tonight ya know i died and i dont reccomend this station
--------------------- MERGED ---------------------------
Exactly how i see it hands on not pen on paper

Same post as the other one. Immaculate clean connection. Get that red shit off there. Go as tight as you can with that nut. Make sure all ring terminals are soldered or crimped with decent gauge wire. I`ve seen people just put the cutting side of a pair of pliers on them to crimp. Do NOT do this. Solder them instead in the absence of a proper crimping tool.
Yep check and check mate was going to do it good anyway... The red shit i believe is to keep the connectors together , even tho they have locking tabs that got me a little too
Hate to think all the other people who didnt open theres and check stuff out

More like some sort of loctite to stop them laminations from buzzing. Cheap nasty transformers will buzz like a 20 stone bumblebee I`m betting if you loosen them nuts.Yep check and check mate was going to do it good anyway...
