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.

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.

Wont heat enough to solder

Hello, does your solder iron --Weller- humming? Also, is the solder tips the right tips for you Weller woldering gun? Are the tips tightened on the end of the solder gun prongs?

Well, if it is humming there is internal short in the windings inside of the gun. Don't mess with. Recyle it by taking the copper, brass, aluminum, and other metal out. Now, if it is not humming.
Make sure you have right tips, make sure that the tip is tightened in the soldering gun prongs.

The working principal of these soldering guns is that they work on low voltage and very high current. The current is regulated to keep the tip from burning into. Just enough current to heat the tipe to a certain temperature.. It can shock you but there not enough voltage with current but it will hurt. and could burn you. Be careful and lots of luck...GB...stewbison

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!

I have recently bought a Weller 201 soldering iron, but in a very short space of time out of 2 projects it has made the glass crack in 2 out 3 projects. Could it be getting too hot.

You need to adopt an on-off-on---- action to control maximum temperature. Try to keep the tip so that the solder flows properly, but the tip doesn't try to burn up. Hope this helps!

1 Answer


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.
