How To Crimp JST, Dupont, Molex With ONE Inexpensive Tool! Tips and Tricks!

Check out the link below for a very similar tool to the one I am using in the video. As an Amazon Associate I earn from qualifying purchases (at no extra cost to you): Engineers Precision PA-09 ► amzn.to/43BUl8Z IWISS Mini Micro 2820 (Also Similar) ► amzn.to/3JfvHAJ IWISS Mini Micro 3220 (Also Similar but with ratcheting mechanism) ► amzn.to/3oFjATZ If you're in Canada, you can get it here for less: ► www.princessauto.com/en/8-in-wire-stripper-crimping-cutting-tool/product/PA0008731028 If you're in the US, search around on Harbor Freight for the same tool! FYI for those who have suggested, or are going to suggest, to adjust the ratcheting crimper... I did try it recently and it still over crimps my JST connections. Maybe it is the style of JST terminal I am using, or maybe it is still the crimper, either way the result is a mangled terminal. Thanks for the suggestions though!

[@akashsaini100]

yes thats true ... i had to order both of these for dupont and other for jst

[@BozesanVlad]

The first tool doesn't have 2 (two) sizes on both parts of the places where you see only one? (for example 0.5 on one side AND 1 on the other side, or 1.5 on one side and 2.5 on the other side) Just asking..

[@roughwaves]

Damn! 1:04 This is the first time an 'inexpensive common tool' actually panned out for me. Hopped down to the Princess Auto ten minutes down the road a picked myself up one of them for 30CAD. Worked great, thanks for the vid!

[@EmbraceMaking]

Glad you were able to find the tool!

[@johnlucas2030]

It helps to put the empty terminal in the crimper jaws and push down lightly so the wings hold it in the correct position. The crimper can then be held in one hand, the wire inserted with the other and crimped without the terminal falling out.

[@keithkamps77]

Just a heads up there is an adjustment on all ratcheting crimpers to increase or decrease the amount of pressure applied.

[@EmbraceMaking]

Haven't played with mine but I'll look into it!

[@BTom16]

I didn't think of clipping the long tails of the insulation arms but I had the same issue with the arms sticking out after crimping. My solution was to crimp again, from the other side. This worked well. The crimps in general, however, did not work well. I had a 60% success rate using the same blue ratcheting tool you have.

[@BozesanVlad]

Doesn't they have two sizes, one on one side, one on the other side, so you have to be careful to not enter in the other half (given that you put in only the wings for insulation and the wings of the wire in, not more)? Just asking because I just got one similar tool and want to know how it works.

[@baileyvolkert]

The connectors with the long wings are designed to wrap around a silicon insert to seal the back of delphi style plugs. They are too long to crimp the bare wire or the wire insulation.

[@k_c_chen]

Not sure how I came across your video. The Princess Auto tool is very similar to the Engineer PAD-11. In their tutorial video, they crimp the bare wire first by having the long wings flush against the tool. When you insert the wire, the insulation also lines up flush with the wings. After crimping bare wires, use the next larger size to crimp the insulation tabs. Just a different perspective and might save time trimming the wings/tab.

[@EmbraceMaking]

Thanks Kenneth, I think it depends on the size of the insulation. Larger wire insulation can probably accommodate the bigger wings/tabs with the inexpensive crimper. Either that or it is possible that the knock off JST terminals just have unnecessarily long wings/tabs. Entirely possible as well.

[@c--b]

Just picked up the crimper from princess auto, and it works great for XH connectors, thanks for the recommendation!

[@EmbraceMaking]

Great to hear!

[@MarcellusSchneider-p3y]

The die set of the Mini Crimp tool appears to be an offspring of Engineer PA-09 from Japan. I have one and it works great!

[@scoot77777]

Nicely done!🎉

[@EmbraceMaking]

Thank you! 😁

[@StevenCookFX]

I have 2 crimpers. One for blade and standard crimp connectors which will not crimp properly if you try to crimp backwards on it. Otherwise it is good. The other crimpers are ratchet type and work well but are not like the ones you have. When you have a crimper than crimps both insulation and bare wire end make sure your not putting it in backwards. It appears in the video that you are using the crimpers backwards. It should not flake off.

[@acutabovefurniturestudio]

What tool would you recommend for a molex sabre with 14 awg wire?

[@madorax251]

hello i want to ask for your advice for crimping tools that are good and easy to use. do you think this type is iwiss iws-2820 or this is IWISS IWS-3220M

[@EmbraceMaking]

Looks more like iws-2820 ... the second one has the same dies but fewer sizes but looks to be a nicer overall tool with ratcheting mechanism

[@madorax251]

@@EmbraceMaking Which one of the two types do you think is easier to use?

[@EmbraceMaking]

Both will be the same in terms of ease of use. The ratcheting one might allow you to adjust the max crimp force though so that would be a nice feature to have

[@IanHolden]

You're using the wrong crimp die for the racheting crimper. The SN-28B crimp die has 2 different size jaws on one crimp, the one handles the wings, the other handles the actual crimp. The crimp die you're using there only has one level and is really meant for a different connector without the wings.

[@EmbraceMaking]

Mine does have a stepped section for the wings... and it still crushes them...

[@Zvika777]

Thanks, After long time of frustration.. found out eventually, you can adjust the crimp pressure by changing position of the pin with the bolt on the crimper.. made better JST crimp :-)

[@EmbraceMaking]

Great tip!

[@nonix3470]

Hi thank you for the little advice on clipping the wings. I couldn't get a solid crimp with my ratcheting tool until I have clipped the wings. :-)

[@EmbraceMaking]

Glad I could help! Thanks for watching :)

[@JoshuaTilton]

Cutting off the wings that were your major complaint against the ratcheting crimper seems to be an unfair comparison...The ratchet crimper is also adjustable for strength.

[@EmbraceMaking]

I haven't been able to adjust it to get it to work properly. It could be that the terminals are not true authentic JST but a chinese replica... so I'm not 100% sure if they are dimensioned identical to the original JST. In either case, this has been working great for me.

[@ronhobyak9902]

When buying pins - What is meant by "B-WIND - Right Payoff" and/or "D-WIND - Left Payoff" ?

[@tookitogo]

I think it refers to the unroll direction of the whole roll. (That is, with contacts on carrier strip, if the carrier strip is facing you, is the spool on the left or right?) Unless you’re buying whole rolls to use on automatic feeding crimping equipment, it doesn’t matter. I recommend buying loose (bulk) terminals for hand use anyway, since it saves you a lot of work, and potential damage to contacts.

[@adamsireii3825]

Can you recommend me molex mx 150 crimping tool

[@Perplexer1]

That particular ratcheting style crimp tool isn't suited for those small 2.0 or 2.54 mm pins. The jaws are too thick. They are for Dupont pins. For the smaller pins you should use SN-01BM or similar crimp tools with 4 mm thick jaws.

[@hondaguy9153]

You can dial down the pressure on that ratcheting crimper.

[@MachuBaxter]

The PrincessAuto link no longer works

[@EmbraceMaking]

Hm looks like I can't find it on their website anymore sadly. They do have this "professional" crimper with many dies... hard to tell from the picture if the right one is included: www.princessauto.com/en/7-pc-professional-quick-change-ratcheting-wire-terminal-crimper-kit/product/PA0008355331 considerably more expensive though :/

[@vicsponjr]

thank you

[@EmbraceMaking]

You're welcome!

[@glendooer6211]

Nothing worse than crimping a fitting only to find the wire pulls out later.

[@EmbraceMaking]

and potentially a good way to cause a dangerous short!

[@glendooer6211]

The Ex spurts say don't solder the wire ..I like to crimp with enough wire out to put a drop of solder on the wire and fitting.

[@EmbraceMaking]

I've seen it done like that.. if you have a good solid mechanical crimp you shouldn't have to though.

[@glendooer6211]

@@EmbraceMaking I have the wrong crimping pliers juts assumed they would do the job ..but no

[@EmbraceMaking]

Ah, I see. Depending on what you're crimping, the ones I show in the video are really great. I couldn't believe how effective they are on such a variety of terminal styles.

[@tookitogo]

Doing both simply gives you the downsides of solder and crimping, without giving you the benefits of both. A properly made crimp is only compromised by adding solder.

[@MihaiDobrin88]

lol bro u do review for hand tools and don't know how to adjust the pressure of a ratchet crimper.... when I hear you saying overcrips or others is not crimping tight enough ... have u ever try to understand how to setup a ratchet crimper before saying is not working? A manual crimper is the worst crimper u can use because you will never apply same pressure and they are banned in many industries where the crimp must be precise. Learn to use a tool before going back to manual crimpers

[@EmbraceMaking]

bro, I recently tried adjusting the pressure and double checked and it still over crimps. Maybe it's the terminals being used, but that particular ratcheting crimper still doesn't work well for me. I understand that the manual crimper won't be as consistent but a good quality ratcheting crimper that isn't a "one size fits nothing" solution is very expensive that most people won't invest in for hobby work.

[@MihaiDobrin88]

@@EmbraceMaking just don't buy from amazon chineese stuff for 10 15$ get a decent one around 40$ and crimping will be a breeze is a investition u make once and will make ur life easier whenever you need to use it
