Question on Installing A Mod

[Jake The Actor]

I have a Magic V with the clip kit and a version 7 PS2. I'm trying to install this seemingly easy chip, but for some reason, my solder will just not stick to the parts I need it to. The solder just rolls around basically. Another thing is, what is a good soldering gun. Mine is one that can change wattage, its a Weller 300 watt max. Any help would be greatly appreciated, due to the fact I'm ready to just grab up all my stuff, including the PS2 and huck into the nearest wall.
