What the wiki says about DAP is true for DAP; it cannot be held accountable for any other brands.
Read the instructions on the can carefully. It should tell you optimum temperatures and humidity, as well as recommended applications and drying times. I've never used any contact cement besides DAP for constructing weapons, so what personal experience I can share would only pertain to that. You may be able to find videos concerning the use of the contact cement you have, even if it isn't in a foam fighting application, which may help you get better results.
If your problem is that it is either too wet or too dry, but rarely perfect, you should take a look at the three most common variables that can cause issues therein:
*amount applied
*drying time
*atmosphere
If you are applying too much, it will take longer to dry, and may dry unevenly, causing problems. If you are applying too little, then it may be drying very quickly, and the bonds that do form may be weak. If you are waiting too long or too little, then you will have similar problems. Depending on the type of thinner used in the contact cement, your drying time may be much faster than DAP's, which may mean you have a smaller window to work within. Finally, make sure you are operating in the recommended temperature and humidity that the manufacturer has printed on the can. They want their product to be applicable in as high of a range as possible, and will give you the best advice as far as that goes.
Addressing those problems may help fix your issue. If it does not, it may simply be that the glue you are using is not suitable for bonding foam. Again, the can should say.
I hope that helps.
