Soldering gun won't get hot enought to melt solder.

If this is the dual trigger Weller gun and your tips are held in place by either set screws or by locking nuts, Just loosen both of the parts that are holding the tip to the gun and then retighten them back up. Soldering iron tips that appear to be tight might not be and this will insure that the tip is indeed tight and also cleans up the connection of the tip to the soldering iron. Oxidation from heating and cooling will cause a tip to not get very hot. Loosen the tip holder and then retighten it. Hope this gets you going again.

If it has been used a fair bit then probably just need a new tip. Can pick them up cheap enough from Maplin etc.

Hello, does your soldering gun humm? If it humms then recycle the parts. There is short across the winding which causing the humm. If not, then make the you have right soldering tip for your Weller gun. Also make sure there is good tight connect on the solder tips with the barrel screws.
It could be a faulty two way trigger switch with internal diac controller. You can order switches from this web site: www.e-sonic.com/aboutus/cat/S/soldering%206.pdf GB...stewbison

A soldering gun is used much the same as a soldering iron for melting solder mainly to connect electronic components to circuit boards. To use it you plug it into the electricity mains and press the trigger. This causes the metal tip to heat up. Allow a minute or so for it to reach full heat and press it to the components you want to solder together. When they heat up press the solder against them. The solder melts and runs on and between them forming a bond. Remove the soldering iron and release the trigger. Once the trigger is released the gun starts to cool down again.

If you've used a soldering iron before you'll probably find the gun more awkward as it cools down every time you release the trigger. It's really only useful for quick jobs where you're not going to need it every few minutes. For other jobs where a lot of soldering is involved a soldering iron is better. The advantage the soldering gun has over the soldering iron is that it heats much faster for quick jobs.

It needs to be at least 600 degrees F and should reach 800 or so. 60/40 solder melts around 600, but flows better at about 700 degrees. Most soldering guns require a on-off-on--- sequence to keep the tip at proper temperature. If your gun doesn't seem to be heating, try tightening the tip nuts. Hope this helps!

HERE their is a collar that slips over the tip holder theirs screws that go through the holes on the tips that secure the melting tip hope this helps

Try tightening the screws that hold the copper element, light corrsion can develop and make a resistance.This can cause the gun to over heat.

It depends on what you say is slow, I have used weller soldering guns and desoldering guns for about 30 years. They come up to top heat in about 3min. If it is taking longer than that then there is a problem with the heating unit. You can call weller tech help number, should be on iron base and they can tell you how to test the heat unit.

# Never touch the tip of the soldering gun. They are very hot and will give you a nasty burn. # Take great care to avoid touching the mains flex with the tip of the gun. The gun should have a heatproof flex for extra protection. An ordinary plastic flex will melt immediately if touched by a hot gun and there is a serious risk of burns and electric shock. # Always return the soldering gun to its stand when not in use. Never put it down on your workbench, even for a moment! # Work in a well-ventilated area. The smoke formed as you melt solder is mostly from the flux and quite irritating. Avoid breathing it by keeping you head to the side of, not above, your work.

Where soldering irons have a heating element that heats a copper or alloy tip; in a soldering gun, the tip is also the heating element. Most soldering guns are hot enough to solder in less than 5 seconds and cool enough to touch in less than a minute. Soldering guns are ideal for the typical home electrical job like connecting speakers or installing automotive accessories. These jobs often have only a few connections to solder so a soldering gun can be a real time saver.
