I'm not saying it's impossible but it is not easy.
A decent BIG tip ... plenty of WATTS .... = no melted body, good joint.
I have a little addition to the good soldering advice in posts here ... with big diameter leads - I make sure the strands are neat and twisted ... then flatten the lead end, tin and solder ... so it lies on the Deans tab nicely.
