Do I need a new soldering iron?

I bought an Ozito soldering kit, it had a 30 watt soldering iron and a 100 watt soldering gun. They haven't been used much over the last 7 or 8 years that I've had them but I can barely get them hot enough to melt basic solder so,I can join wires. Got my infra red temperature gun and it recorded a maximum of 280 degrees Fahrenheit, the solder I believe melts at 360. Do I need a new soldering iron, I've heard the gas ones are easier to use. I only need it for basic soldering usually wires that have frayed or torn.
