The supplied USB-C PSU is not earthed (2-pin) and so capacitive coupling leakage is occuring onto the USB-C connector shield. This is directly connected to the probe tips. Here in the UK we are on a 240VAC supply and so I measure double what Northwest get, i.e. I get 110VAC measured (BM786 DMM) between mains socket earth and the probe tips. If this is a worry then try and find a different USB-C PSU that is earthed, or use the barrel jack to on the iron to a bench PSU.......thats what I am evaluating right now.......or go ahead and try earthing the Sequre PSU USB-C shield connector (subject to safety checks). Note: My JBC soldering iron tip is earthed due to having a mains earth connection
@@IanScottJohnston Wasn't NorthWestRepair also seeing leakage from his bench power supply? He did a follow up video where I thought he used the barrel connector connected to his bench power supply and saw similar leakage or am I just cornfused like usual? ;)
@@bblod4896 It looks like Sequre realized this. I looked on their site and they do supply different styles of tips. To my surprise, they actually have a set that is for IC removal! Each side has a flat plate. I do find that the tips are really expensive, however. Still, this is a really nice device. I have a hot tweezer set, but it's a lot more bulky. But still, these have been excellent.
Watched northwest fix video on his he had a follow up video about the voltage leak of 50v AC and high DC plus not being grounded they may not be safe also the temps are out by 20c on his
The "paddle" shaped tips are good for larger joints and IC's. I haven't seen this style C210 tip available elsewhere so be sure to pick some up if you think you might need them. Only problem is loosening and retightening 8 grub screws, two of which are blocked by the opposing tip. I tend to only use the 3 screws that are easy to access, they should consider 3 instead of 4 and orient them appropriately. The tips fit firmly into place, the screws only prevent rotation. Standard tips are C210-IS and around 2.1+/-10% ohms. C210-K are also an interesting option, I bought some but did not use them yet.
If I get a psu with a ground prong into the wall will it fix the voltage leakage (there was a great comment here addressing this but it disappeared, typical youtube, their auto-deletion of comments for God knows what is utter nuts)?
Thumbscrews for the stand would make sense if its a portable tool as indicated by the carry case, that way you wont need the screw driver... on another note how much current leaks from the tips?
C210 tips seem to have a very limited selection available, at least of the cheap ones. There seems to be 3 standard ones. Had they used C245 there would be a LOT more choice. Could use some of the blade/shovel tips and use them for removing 14 pin ICs, etc. edit: Looking in to it more there are some other tips but nothing larger than the 3.4mm knife.
Well, I need to correct this. Sequre now has their own special tips for ICs. 3 and 5mm wide ones with a square end and they show an angled end one as well but don't list it for sale (yet?). Edit. YIHUA seems to sell the same set including the angled one.
You could have changed your current max value to 5.0A to make use of the 100W power supply. I wish the sleep would give a beep warning. When trying to remove larger parts like alum caps, the wait to heat up can cause the sleep to occur before unsoldering is complete, embedding the tips into cooled solder without warning. I increased the sleep time because of this. I prefer brass sponges too, but not for such small fragile, J-shaped tips. I have been using a 140W power supply 28V/5A, but there is a quirk with failure to bootup on 28V, so I have to set the max voltage to 20V before shutting down. Richard (LER) had the same problem and was convinced his charger was bad! Sequre was very responsive to my concerns and are seeing if a firmware update can resolve this. Funny how unfluxed SMD components make handlebar moustaches after you reattach them.🤐
Check AC from tips to ground
@@ovidiu7290 no issues there, at least on my USBC supply
@TheDefpom Hi, did you use an oscilloscope to check it?
Northwestrepair Tony checked this tweezers and he got some conserns about them.
Happy New Year
He doesn’t use what he opens

Very nice, but looking at the tips, it's definitely intended mainly for smd de- soldering.
Agreed. The tips look round. I'd prefer a flat tip.

I ordered one + extra tip set

The new year celebrations will commence shortly, please stop work at once!
I never stop working.... I am ALWAYS busy, even if I don't want to be.... I was writing code for someones website 5 minutes ago.
@@TheDefpom The various AI apps write excellent code.
you did put 325°C !? how did you did that? everyone else says its only by 50°C steps
@@simonspeaker in the video I show how to change the step size, I guess you didn’t watch that bit?
Interesting piece of equipment. Thanks for the review. Happy New Year to you and your family 🎇🎆🎇🎆🎉
how to update firmware when it shows v16.00 ready? thank you and happy new year.
