I've found the PA21 can be used on a VERY broad variety of sizes of pins by using the above four step process. If you need to do a fair bit of crimping of JST type connectors, or Dupont, then this tool is definitely worth the investment.

I liked the IWISS tool so I purchased their PEX pipe crimp tool, another winner, I can get into areas my other tools can’t. The cheaper ones didn’t even have a forming/dimpling bump in the top of the jaw as shown in the pictures above, where the terminals are formed to curl back down and into or across the wire being crimped.

It is important that the electrical connection is gas tight without any voids between the wire strands and the terminal. You also clearly and intelligently divided the article into sections, giving the reader the ability to go straight into what was most important to them. At this point it’s a good idea to give a firm tug on the contact and wire to test that there is a solid mechanical bond. Art of Connector Crimping” about my article where he pointed out that I am not the first person to come to that conclusion. Finalize crimp by giving it another good firm tug test, and if needed it’s handy to have an eye loupe magnifying glass around to provide a visual inspection, watching for any loose stranded wires or improperly seated crimps.This is the best of the bunch by some distance, it is more expensive than other types of generic terminal pliers but the quality of the crimp is superior.

At the same time, I will say that I personally do not like ratchets, nor do I like crimpers that have each station with the dual width "stepped" slot for performing the bare and insulated crimp in one operation. As a result, your viewing experience will be diminished, and you have been placed in read-only mode.The perfect crimping tool for the JST family of connectors, including the JST-XH connectors widely used in 3D printing or CNC and laser engravers. Ah, looked at the wrong datasheet; but interesting one says to use the same dies and the other says it cannot do it.

I get nice crimps with a single pass for both insulator and conductor, but the crimp terminal needs to be inserted precisely. The first thing that I will say about the crimping process is that you should consider not doing it. I just believe the four step can deal a little better with things like a wire that is too small for the connector, or too large, and/or a broader range of connectors, or etc. If you are reading along crimping a different contact for a different connector and your pull test fails try jumping to the next size down on the crimper with a new contact to see if that fixes your issue. There is no single crimp tool for all terminal types, and what works well for one individual may not necessarily work well for you, and that has a lot to do with wire type, brand of terminal, tension setting of the crimp tool being used, the level of polish on the dies in use, and probably most notably, the speed with which the crimp cycle is executed.If you see somebody in an online video using a crimp tool and obtaining satisfactory results, keep in mind that that person's circumstances will not necessarily be the same conditions of use for you.
