Several things can be going wrong. As far as your crimp tool goes, it doesn't sound like the problem. Problem one: you might not have used the proper sized crimp connection. Be sure to match the connector properly to the gauge of wire. Problem two: you might have purchased poor crimp connectors. It may not seem the case to you, but through many years of experience with crimp tools, it is often a poor brand connector that can cause problems. Before discarding the idea of a ratcheting crimp tool, try using a different brand of connector and see if that solves your problem. Problem three: you might not be placing the connector in the proper section of the tool. Before you crimp, always make sure that the crimp you are making is inside of the proper colored crimp slot. If you dont do this, I can guarantee that your crimps will not hold up to any kind of physical load. I would always recommend using a ratcheting crimp tool. I have had mine for several years and it has seen the production of many robots and it still crimps perfectly. Try to keep using your ratcheting crimper because I don't think that is causing your problem.
