Soldering Woes

[eyedebee]

Hi,

I've just got myself a new ESC, I'm really struggling to get the 12AWG wires tinned and even the pre-tinned wires are being difficult to solder to the ESC posts. I'm in a mess, so I've borrowed a desolder pump and I'm going to start again.

I've got a Maplin 50W Solderstation which has until now served me well but I think I might need something with more power. I've tried changing to a wider tip- still struggling.

Has anyone got a cost friendly soldering iron/station they can recommend? Or is it me?
