I made a similiar post a little while back. Before I had a Radioshack iron 15/30watt, for some reason it stopped working. I picked up a new one from sears. This one is 45watt for some reason it was the lowest watt iron that they sell. I've been told a few different opinions as to how hot I need my iron to be. I notice though in every video I watch on the subject guys are always using those guns that get up to 140 watts. I'm having trouble soldering twisted wire together. Such as wire to plugs for ESC and Charge Leads.

I had the iron on for like 45 minutes. I only heated the work area and not the solder. I kept touching the solder to the wires and it would never melt. I just burned my work bench and fingers holding the wires. Do I not have the correct wattage iron for doing this stuff?

I watched a video online and the guy uses a high wattage gun. Touches the wires once or twice and the solder flows right across it. The tinning of the new iron was also mentioned. When I try and tin my iron the solder just bubbles on the end of the solder wire and never drips onto the iron.

Would appreciate anyone's help.
