Review of Cooper Tools GT7A Solid State Soldering Guns, Operating Temp.: 600 F or 700 F

I have owned this since the early 1970s. This gun is ideal for many electronics soldering applications. It is very light weight but heats up quickly. It provides more than enough heat to, for example, solder Amateur Radio antenna connectors. Also great for repairing hand wired circuitry in older radios and automotive soldering.

Because it is temperature controlled it is easy to prevent burning items with too much heat, as is possible with normal soldering irons. This really benefits the quality of the finished product soldered connections. I hesitate to say that this gun makes soldering easy, soldering is an art. But it does make soldering easier.

Be careful, when you are not actively soldering let go of the trigger. If the gun is not actively touching some metal to act as a heat sink it will turn itself up to full temperature and burn out the tip prematurely. Until I discovered this I replaced a few tips. Now they seem to last forever. The tips cost about half of the total price for the entire product. Let go of the trigger when you are not soldering, it will heat back up very quickly when you are ready to solder.

These do cost more than run of the mill guns but there is a reason. This gun is in a class of its own.
