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.

Do stained glass soldering tips go bad or stop working. I have a weller soldering iron that doesn't heat up hot enough to solder. is it the tip or the iron

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.

Soldering gun melts tips

180 watts is way too much for a soldering iron unless you are repairing copper pipes or soldering 4 gauge wires. You can't just let that stand, it must be used or it will overheat. Harbor freight is were you buy tools that are meant to be used one time. They are junk - I'm not judging you because I don't know what project you have - it is likely a one-time project.

Having trouble with solder sticking with metal to metal applications

Soldering is intended for soldering alloys together such as copper, silver, gold....solder does not stick well to steel and aluminum...also, you need to use a flux when soldering...this flux cleans the connections of impurities and allows the solder to stick to the metals to be joined...Judging by the iron that you looks like it is mainly used for very small soldering applications where not too much heat is required...If you want to solder larger items(such as soldering to a metal chassis) then I would recommend using a soldering iron or soldering gun with more wattage

I just bought the soldering gun but the instructions on the package aren't very useful how do i use the gun?

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.

I am making jewelry with the tips are dispersing...what is my problem. Should I use a different watt. All that I am doing is soldering over copper foil to broken china.

25 watts is a pretty light iron for the kind of work you are doing, but if it works---. Tips that are just bare copper tend to erode over time (the heat causes the copper to mix with the solder and thus erode). The better tips have iron plating over the copper which protects the copper. Silver solder applied over the bare copper works in much the same way and can be applied with a propane torch. Hope this helps!

these are not worth repairing as the main part of a soldering iron is the transformer which is what causes the tip to get so hot, so if yours is giving off smoke and excessive heat probably the transformer is starting to cook itself which means it has to be replaced. I would guess that the transformer will cost you more then a replacement soldering gun on ebay would cost. Hope This Helps Don

Weller model 550PK heavy-duty soldering gun is slow to heat up

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.

Tips are corroding & disappearing

That is normal for a soldering gun especially if you are using acid core solder. I do a lot of soldering with rosin core & have to change the tip about every 6-8 months. Just get a couple of new tips. Rick
