Is The Iwiss 3220M Ratcheting Crimp Tool Any Good? | Voltlog #431

When it comes to crimping small connectors like JST, Molex, or Tyco, having the right tools can make a world of difference. In his latest video, Voltlog takes a closer look at the IWISS IWS-3220M ratcheting crimp tool, which promises an easier and more consistent crimping experience compared to traditional non-ratcheting tools.

One of the standout features of the IWS-3220M is its ratcheting mechanism. This not only makes the crimping process more user-friendly but also helps ensure consistent crimps by preventing over-crimping. The tool also features a dual-crimp design, allowing you to crimp both the insulation and the electrical connection in a single action – a significant time-saver.

During his testing, Voltlog found that the IWS-3220M did indeed offer a notable improvement over the non-ratcheting IWISS mini 2820M he had reviewed previously. The ratcheting action made it much easier to position the crimp and wire correctly before crimping, and the dual-crimp action streamlined the process.

However, as with any budget tool, there are some limitations. Voltlog noted that the precision of the crimping die might not match that of more expensive professional tools from brands like Molex or Tyco. Additionally, finding the right die size and ensuring the correct wire insulation thickness is crucial for achieving a good crimp.

Overall, Voltlog recommends the IWS-3220M for hobbyists and those working on smaller projects. While it may not match the performance of high-end crimping tools, it offers a significant improvement over basic non-ratcheting tools at a very reasonable price point.

Hello everyone and welcome to a new InTheMail the series that will touch both your passion for electronics and your bank account at the same time.

We’re gonna start with this interesting looking controller type module. So we got what looks like a big switching device here that probably needs a heatsink. Well this is a beefy triac, it can do 100A and can also withstand 1000A non repetitive peaks. We’ve kinda started from the wrong side, from the output but that’s what stands out from this module. We have an opto-isolator which has a triac output driver, separating the two sides of the board. Let’s check the clearance on the back, they have something like 3mm clearance in this area. If I were to design this, I would have done it with at least 5mm, I don’t see the point of extending this ground poor so close to this track which is on the hot side.
