Weller GT7A Solder Gun, Solid State, 700F, 150W, Black

This is not a popular model and not easy to find. I have used this model in my electronic repair business for overy 30 years. It produces more and quicker heat for mid size repairs from smaller to large wires. Even battery size wires to lugs. The tip stays tinned and can be cleaned with the swipe of a wet cloth. Wont do small component replacement like a pencil iron, but it not designed for that. Well worth the money. As the saying goes. The only good connection is a soldered connect.Hope that helps. First 5 star rsting from me.

I only use this gum at home for small projects. I don't think that I have had it a full year and it has stopped working. It is in the trash now.

After a long look years ago I just discovered that this soldering gun is available again! I haven't yet ordered a new one from Amazon but couldn't pass up giving a review of this previously impossible to locate item.I have worked in electronics most of my life but now being retired I use this iron for soldering power wires on lipo batteries and other model airplane heavy wire connections and for model railroad track soldering on the type of tracks that can accept solder with flux. This gun also is very convenient in soldering smaller gauge wires especially when away from a soldering iron station.First a description - the handle is a type of plastic shell with a trigger mechanism - that is all. The working heating part of the soldering gun is in powerheads that plug into the shell. There "were" two types of powerheads. One of these is a point type tip and the other has a thicker chisel type tip. I believe but am not certain that the one to be purchased here is the point type tip - look in the description. Both the chisel and pointed heads are rated at 150 watts. The pointier type head is the one I use almost exclusively. The size of the chisel head makes it more difficult to use for pinpoint soldering and since the chisel remains a 150W head it doesn't extend any more heat then the pointed head. The chisel head does present more surface area so it will transfer the heat quicker to larger areas. (As far as I know the chisel head, although worth mentioning, but might not even be still available)Although I do have the other standard type gun for situations where only 250W can do the job - the Weller powerhead gun has multiple advantages since it is lighter, heats up quickly, gets into much tighter spaces, and has enough power to do most jobs. I can solder my model airplane #12 and #10 gauge stranded battery wire with it effectively. I've also made good solder joints down to #8 when the connection won't bleed off too much heat. In this case I also use a special flux. On the other side I often solder up to #18 and #20 gauge wires. Above that I'll typically use a good iron.So what is the downside to this gun - the only reason I give it a four rather than a five rating? the downside is that the thermostat that controls the heat can be finicky at times. After the iron starts to heat up everything is OK. The issue is that at times and for some unknown reason the gun won't even start to heat up. In this case I do the obvious - clicking the trigger several times or just waiting a little longer and finally - eventually - the heating starts. It is almost like the thermostat needs a kind of kick start sometimes. Initially when this first happened years ago I assumed that the particular powerhead went bad. However I had purchased other powerheads (the last one about 5 or 6 years ago) and even when newer this problem sometimes arises and then goes away. In a final analysis although this sticky issue is sometimes frustrating the overall benefits of this gun over any other more than compensates - so I continue to like and use.

This is the very BEST soldiering gun ever made. Some would say that this is why the manufacturer discontinued it. Fortunately, replacement cartridge tips continue to be made in southeast asia.

twice the heat at half the size of the bigger gun they sell at Home Depot and here on Amazon. This soldering gun is one hot mutha!!! It works great on everything down to 10 ga

This is complete JUNK!!! DONOT WASTE YOUR MONEY.

Great solder iron. Light in the toolbox, rugged in the field.

The soldering gun I received was used.
