Holy Moly!

The unit is big, pretty heavy and hard to weld. But Boy the power! Insane! Instant melt. If a regular solder iron is a Hummer, this guy is M1A1. You probably don't need it for most of your projects, It's simply too big too heavy, you still need to buy a smaller one. But when you do need it, this is the only unit that can get the job done.

WOW great speed and heat

I have been soldering for close to 60 years and have used so many different irons, tips, guns & torches I have lost track of all the names except for WELLER. I was surprized at the speed of getting to soldering temp.. also the amount of heat does very well at heating larger pieces. I do solder some metal/glass items and I was very well pleased at the heat right to the exact spot I needed to re-solder. also I wanted to solder the ends of wire to a car battery. I do not like to gas solder this close to a battery and this electric gun works very well and very fast. I still have my older WELLER gun, it is a lot lower heat, I have had it for more then 20 years. I would buy another WELLER product anytime I need soldering tools Martin Harris Edgewater, Florida

Been using this exact model for 65 years!

Works great for large soldering jobs. Main trick: You have to tighten clamps on heating element for it to work. The poor reviews are from people who don't know this. There are two set screws that need tightening. They hold the tip in, but more importantly, establish a low resistance contact. If you want to go cheap, consider Har*** Fr***** model for 20$ range, but Id buy Weller. (Yes, I'm 75 and first used at age 10. I bought this model again recently, and it is identical.) Very good tool for large work.

Be sure to clean the contacts

I thought that I had a bad solder gun, but after communicating with the manufacturer, I discovered that the connections to the tip must be periodically checked, since it's the electrical current passing through it that produces the heat. I now have a soldering gun that's ready to use in seconds.

Perfect tool for the solderer of fortune

Pros: Wow, I had no idea how great a soldering iron could be. I've been using cheap irons for years, waiting 20 minutes for it to heat up, losing too much heat on larger pieces, forgetting to unplug the iron after I'm done, etc. This iron does not have those problems. It takes about ~20 seconds after pulling the trigger on a cold start to melt solder. There are two settings, 260W on half trigger pull and 200W on a full pull. The gun also has a light to help illuminate your work piece. It comes with three tips: solder, cutting, and smoothing. Cons: This is for large soldering/burning/cutting jobs only. I was hoping to pick up a fine tip to do smaller jobs, but it doesn't appear Weller makes them. Perhaps I can grind one of the larger tips into a finer tip. The window on the carrying case is not very sturdy, I've almost dislodged it a couple of times already when closing the case.

The only soldering gun to buy

This in the only soldering gun to buy if you are trying to construct anything with low temperature solder. (The only exception would be if you were doing electronic/electrical soldering where you need a "pencil" style soldering gun.) All other soldering guns, even those made by Weller are "mickey mouse tools" because they just don't get hot enough. Spend the extra money to purchase this soldering gun. This soldering gun has a few tricks. - The soldering tip MUST be inserted all the way into the gun connections. - Buy extra tips. - Loosen and tighten the threaded allen screw that hold the soldering tip in place. - Make a point of buying replacement screws (regular slot or Phillips head screws) for the allen screws. Eventually the allen screw is stripped on the inside. Using a screwdriver for this loosening and tightening is easier with a screwdriver.

Hefty soldering gun!

This thing's a BEAST. Wow, 4x's heavier and bigger than small Weller I had been using, quality seems on par with my 20 year old small gun it replaced, time will tell if it lasts as long. I know I abused the duty cycle if my old iron and it always came back for more. I'll update for good or bad as time goes on.

7 year warranty

I have not tried to use the warranty since I just got the product. The fact that it is a long one gives me hope. I checked the screws for the tip before I heated it and tinned it. I like the quick heating and the solid feel of this gun. I bought some So-239 connectors to make ground plane antennas and I need a high power fast acting gun. If you follow the recommended 1 minute on 4 minutes off duty cycle...not bad really considering its 10 second heat up time, it should last forever. From welding I know that duty cycle is misleading. If you set up your joint and then solder for 20 seconds...then set up another joint that takes maybe a minute...then solder again for 30 seconds then you will never exceed the duty cycle. I find that the older I get the less I hurry anyway.

Great Soldering Gun

I had a Millers Falls soldering gun for over 30 years and it was older than that, the case was broken and had some other issues so I decided to get a new gun. The case from this one actually fit my old one and this gun is built nearly exactly the same. I expect to hand this on down just like my old one was to me. A most pleasant surprise to find a product "still built like they used to "

Heats fast

I really like this soldering gun. My first one and got to use it on a job fixing wiring on my Jeep recently. It heated up quickly just make sure the ends are tightened down or it won’t heat up properly. My only issue is the tip that came on it burned through very quickly and I had to replace with another that came with. I guess I need to buy more tips. Not sure if operator error or poor quality
