According to Ignoramus25589 :
I will soon need to crimp many terminals on many short, but thick, 1 gauge or 0 gauge cables. 0 (1-0) gauge uses the larger of the two AMP hydraulic crimp heads, and the smallest set of dies to fit it. (Total range -- 1-0 though 4-0) Hmm 1 gauge? The smaller of the two AMP hydraulic crimp heads covers #8, #6, #4, and #2. I don't know of one for #1 at all. Are you sure that it exists? The larger head is either powered by a hand pumped (or foot pumped hydraulic system capable of 10,000 PSI, like the porta-power units, or by an electrically powered pump which cycles to maximum pressure and then releases automatically. The smaller head can be powered by the same, or is available with a hand-operated pump built in. Crimpers are just too expensive. It depends on how long you watch eBay, waiting for what you want. I have (hydraulic) crimpers and dies for #8 through 3-0, and am still waiting for the 4-0 dies to show up. I also have the purely mechanical crimpers for similar terminals down through #26 or #28 IIRC. Is there some way to get acceptable crimps without a crimper. Acceptable to whom? They would certainly not qualify for mil-spec work. (I'm assuming that you're talking about the PIDG style crimp terminals, which have a collar which grips the insulation.) If you have a hydraulic press, and can develop around 31,000 pounds (I think) with it, you could make holders and guides for the dies for the AMP for up to the 4-0 terminals. Then, all you would need to find on eBay is the dies themselves. I guess, also, that I could buy one on ebay and later sell it, but I would prefer to avoid that. With the sizes which you are talking about, I think that you will need two crimp heads, to cover your stated requirements -- assuming that you can find dies for #1 wire terminals. AMP does not list them for the crimpers which I have, at least. If you already have a porta-power, you can use that to drive the heads. Here is an example of the hand-held one for the smaller dies (#8-#2), though it it in an eBay "store" and is *way* over what I paid. Auction number: 7548679099. The second photo will show you what a pair of the dies looks like. The red tape around one of the handles is intended to show that it is loaded with dies for #8 (or #2, which have the same color). #6 is blue, and #4 is yellow. I've gotten similar crimpers for as little as $15.00 at a hamfest -- with one set of dies in it. AHA -- here is a much more reasonable one which was missed by my first quick search: 7553590509 And that one is even the later model of the hand-pumped crimper. Still the wrong dies for your application. It has the #6, and you need the #2 (the closest to #1 that I know of). This one is at only $25.00 with about 11+ hours to go as I post.

Yes it exists. http://cgi.ebay.com/ws/eBayISAPI.dll...MEWA%3AIT&rd=1 ButI can not read what die takes. Hmm ... Bundy -- yet another maker. AMP and T&B are fairly interchangeable in the pre-insulated terminals. These look like they are un-insulate (just a color coding layer on the outside), so perhaps a #2 die would work well on these without the insulation. The starting bid is certainly attractive. Thanks for the pointer -- I suspect that Igor should go for these terminals, as he is likely to have to pay that *each* for ones bought from a store. :-) Enjoy, DoN. -- Email: | Voice (all times): (703) 938-4564 (too) near Washington D.C. | http://www.d-and-d.com/dnichols/DoN.html --- Black Holes are where God is dividing by zero --- |

I get my large terminals from a battery store; my local has all the large sizes, in copper and some in tin plated copper. The marine stuff gets really big, and the batteries equally big. Those I buy are uninsulated, which is fine for me. I use a hammer crimper and sleeve them afterwards. The insulated AMP terminals require a special crimper made for them, hence the above tooling. Quality insulated terminals of that size range all pretty much conform to the same standard, so any crimper made for insulated terminals of a specific gauge will work with them. If you look around the outside of the stud hole you'll see the numbers that relate to the stud size for all terminals, insulated or not. I don't think you'll see that kind of terminal used much on welding cable, they usually tend to be bare since insulation isn't really necessary. Insulated stuff is more expense than its worth. |

The high tech wire we used was 3/4" diameter 1000 strand and would bend in a 4" radius.
It took the 500 amp -2v current to the buss. (where others showed up) Makes great jumper cables - so I am told. I got a harness, but the good stuff was gone. I got away with the 3/8" and 1/2" stuff. Have some fantastic 10 ga size that carries current! Long lost the manufacturer of this very flexible and very high current wire. Using some in the current (high current that is) project now.

In article ,
says... The high tech wire we used was 3/4" diameter 1000 strand and would bend in a 4" radius. It took the 500 amp -2v current to the buss. (where others showed up) Maybe DLO, Diesel Locomotive Cable? http://www.elektrimna.com/DLO.html I used several parallel strands of the 777 MCM size on a project that required a flexible connection to carry 7500A @ 15V. For the last 2 feet all the current ran thru a water cooled jumper, much like the power cable on a water cooled TIG torch, that was about the size of your finger. We monitored the water flow very closely. Ned Simmons |

Nope - it was something else - searched and still can't find it.

Apparently, the crimp is lot more critical than with coarsly stranded wire-- if you don't practically mush all the strands together into solid metal it can fail catastrophically fairly easily.

Might be - Suspect it had to be a gas tight fit. The copper was really pure to be
so supple.
