Is The Iwiss 3220M Ratcheting Crimp Tool Any Good? | Voltlog

- Опубліковано 10 жов 2022
- High quality PCB Services pcbway.com Join me in this video where we take a closer look at the IWISS IWS-3220M ratchet crimp tool which can do very small crimps like: JST-SH, Tyco D-1000, Molex CLIK-Mate and others. Is this tool any good? I’ll test it by trying to crimp some JST-PH connectors. And I will be comparing with the previous IWS-2820 non ratchet crimping tool that I reviewed in Voltlog 425.

#IWISS #Crimp #IWS-3220M
I have a couple of popular videos on my channel where I take a look at some affordable crimping tools, the most recent one Voltlog 425 where I looked at the IWISS mini 2820M, this is a dual action crimping tool, meaning that you will have to crimp first the insulation then the electrical connection, it’s cheap, it works but it does require a bit of extra work, a bit of extra attention for correct positioning of the crimp on the die, careful applying of force and a bit of practice on the user side to get a usable crimp.
My viewers recommended in the comments that I should also take a look at the ratcheting crimp tool from IWISS which is isn’t that much more expensive but should be easier to use, less fiddling, will crimp both parts of the crimp at the same time, won’t let you apply too much pressure which would crush the crimp so overall it should provide a better user experience and better crimps, at least in theory.
The model number for this is IWIS-3220M, comes in similar packaging, once again, there is some great information on the packaging itself, the list of supported crimp types, list of wire size vs the correct slot on the die as well as a bunch of tips & tricks on how to get a good crimp. This tool is rated for AWG32 up to AWG20 wire size in sq mm that would be 0.03 up to 0.52 sq mm, for my particular use case this is the range of crimps and wire sizes that I commonly use at my electronics workbench.
By the way should you decide to get one of these after watching my review there will be some links in the description of the video with places where you can order this tool so check them out.
Construction wise, like I mentioned earlier, this is ratchet type crimp, quite a weak spring action on the mechanism, I would have preferred a bit more force in the spring they use but that shouldn’t affect the quality of the crimps. There are rubber handles which feature this lock here to prevent them from sliding on the metal handle, that’s nice attention to detail. You would have to watchout to not get your fingers caught in the ratchet mechanism which sits here on the handles.

Thanks for the info. Ill be getting one soon for my car repairs.
A possible reason for the non-ratchet is if your insulation thickness means it would be better to use a larger die for the insulation and a smaller one for the wire, it's not really an option with the ratchet.
That's a valid scenario, thanks!
3:45 No idea what you mean about the jaws... Iwiss clearly claims on the product page that those are wire-EDM cut dies, NOT the poorly-detailed cast ones that countless cheap tools come with. This is supported by their two-layer construction: although EDM as a process can cut stupidly complex shapes, WIRE-EDM can only cut vertically through the entire workpiece so it could not make the stepped double-crimping dies as a single piece (while die casting could) - hence the two separate layers of the dies. As for the tool, I bought one from a local store, delivered the next day, after your original video - and I'm quite happy with it.
I don't know much about metal fabrication techniques but one thing is for sure this is not a CNC'ed.
@@voltlog Well yes but actually no. Wire-EDM _IS_ typically a CNC process. Think of it as a "bandsaw" that can cut in any direction because the "saw blade" is not flat but instead a very thin continuously spooled wire, which cuts with an electric spark immersed in a non-conductive liquid instead of teeth. Oh, and the trajectory of the wire is typically CNC controlled. It can cut fine details no endmill can ever hope to, because the wire is ultra-thin. But due to its "bandsaw" cutting style, as I said, it can only cut through the entire part in a straight line, ie. no "steps" in height are possible. At any rate, I for one find the detail of the dies quite good, far better than any cast die.
@@voltlog It’s obviously CNC-machined using EDM, just as Attila said. It’s not stamped. You can see the machining marks inside the jaws as lines from front to back on each half of the die.
This tool is the one I use at home for JST XH contacts, and it works quite well. They’re almost as nice as crimps done on the original JST tool at work. But without a locator, it is of course far fiddlier to use.
Dzięki. bardzo wartościowy materiał. Dla porównania chętnie obejrzałbym test zaciskarki YE-013B(R).
Good timing. I have one of these on the way from AliExpress.
Good choice!
If i use this tool which slot do i use to crimp
JST ZH 1.5mm with 28awg pvc wire?
JST-PH 2.0 with 22awg Silicone wire?
Great video, but you missed one very important part on the crimping instructions.
The die is made of 2 halves, one half is lower than the other half.
It’s important to tell people to insert the connector in the die with the lower side of the die on the side of the connector that will crimp the wire rubber isolation, while the higher part of the die, will be on the naked wire side of the connector.
EDM does the magics. I got a Cinlin-Crimping-tool with cheap jaws and paid additional >11€ for the EDM-jaws (watch out: they must fit). The cheap 2549 doesn't work, but the EDM works perfect. This IWIS-3220M have EDM-jaws.
The 2820M is also a nice tool. This can be handy to use thicker insolated wires.
I use a PA-09 similar to the non-ratcheting tool you had on the video. One common problem I have is the crimp getting stuck in the tool, maybe because I'm applying too much pressure. Did you have any issue with the crimp getting stuck in the tool?
Yes crimp will get stuck on this ratchet crimp tool.
This is my biggest annoyance when crimping connectors. Getting them released without destroying them can sometimes be really tricky.
Haah, I was going to buy the cheaper crimping tool in this video a while back. I was apparently in a hurry though so I did not read the description well enough and instead I got the wire stripper tool you mention on this video, or at least something very similar. Ah well.
In that case I would recommend going for the ratchet type shown in this video because it will make your life easier.
This seems to be basically the same as the generic SN-28B crimpers I have. However, I need to crimp JST-XH and dupont mini-PV connectors. I have read that this is not the correct tool for the job. Does anyone here have experience with this? Thanks
I'm pretty sure it will do JST-XH just fine.
@@voltlog Very well, thank you for your reply!
@@I967 I have lots of experience with XH and Mini-PV, using both cheap and official tools.
SN-28B is unusable for XH or Mini-PV. It’s for small spade connectors (…28B == 2.8mm spade). The jaws are simply too thick for either of the small connectors you have.
The IWS-3220 is what I use for XH, I think it works quite well for them. (Not as good as the original JST tool at work, but still a good crimp.)
Mini-PV and clones are picky contacts to crimp, since they need the rolled (circular) insulation crimp, which VERY few crimp tools have. Honestly, I recommend being patient and waiting until you find a used official tool for cheap on eBay. (Or a really similar official tool for a similar contact. At home, I use an original tool for AMPMODU MOD IV contacts that I got on an auction site new for $60, and it’s wonderful.)
@@I967 I don’t know if you’re familiar with the eevblog forums, but I have a big thread there titled “Affordable crimp tools for small connectors (Dupont, etc.)” that goes into various crimp tools for DuPont contacts.
Yeah, good to see you convert to ratcheting
Please see my comment on RevC tasmota underfloor heating
mini version is more versatile. I crimp faster with old mini version
I didn't see any crimps that I would consider "good" or satisfactory. Junk.
Yeah, not a single crimp he showed was even remotely acceptable. But as someone who owns that same tool, I can tell you that it does work well, in skilled hands, for many small connectors. The tool is definitely not as good as original tooling, but it isn’t total junk like so many cheap crimp tools I’ve tried. (I have a bin full.)
