Hello, I am running new wires from the battery back, 2 gauge, and I would like to terminate the 2 gge with a ring terminal. Any advice on soldering the terminal on? Should I just crimp on, then heat up best I can, and hold solder to it til it takes? Or is there such a thing as brush-on solder paste that would make the application more effective? I know that it can be difficult to solder 2 gge because it is so thick and absorbs so much heat. TIA

Definitely crimp first.
Then solder - if that is possible or desirable.
DO NOT solder and then crimp (or not crimp)!

It will take a torch of some sort. Do not apply heat to the wire itself, apply the heat to the back side of the ring terminal. If you heat the wire it will oxidize and not solder well. It will not take a large torch, Radio Shack sells one for 20 dollars. You will have to buy fuel elsewhere. Or lowe's sells one for 15 dollars with a small can of fuel.

A big soldering iron works fine! Just as Mr idiot said, apply the heat to the back of the terminal and allow the ring to heat up, the start to apply solder it should melt easily and coat the entire ring and copper!

When he says a large iron, It will have to be one of the following
120 Watt
175 watt
Both of the above items are Weller products.

i just use a walmart brazing torch, the kind used for soldering copper pipe, and good old lead solder(i know,i know its bad for you but i think it works better then the lead/tin mix or even the silver solder)

I promise you these will be the best option for you... Much easier to control, and no flame to scorch 4 inches of your insulation, either...
Any good electronics store (i.e. NOT "The Shack") will be able to get these for you, if they don't already have them in stock. ------------- It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

As others have thoughtfully said, I crimped and then soldered my 2 ga. to rings with a plain old plumber's torch on LOW output. Heat the ring, not the wire, touch your electrician's grade solder to the back of the cup and allow the solder to melt into the connection, heat source removed. Works like a charm. :D I then brush the ring clean to remove the oxidized copper after it has *cooled*.
