Weller Pyropen WPA2 extinguishes itself after a few minutes.

The iron seems to cut off the gas supply by itself after a few minutes. Same issue with different tips. The gas container is half full, containing highly purified butane gas. I've tried releasing all the gas form the bottom, and refilling it. Also checker for stuff blocking the tip. Issue keeps coming back... Or is it a safety feature? Guess not... If I leave the Iron for a few minutes (off) it wil engine again. Butane crystallising somewhere in the system??? any suggestions?

Gas (condensation really) may be freezing and constricting flow. Try warming the tip a bit with a hair dryer see if it goes longer.

SOURCE: no longer melts solder with tip....

You have burned out residue on the tip. Clead it off with a damp cloth when the iron is hot. If this doesn't get it all, use steel wool. Immediately afterwards, get flux & solder onto the tip or it will get coated again.

Hi, I'm not sure the tip is defective. Check that the tip is screwed in tight. If it is not good and tight the tip will not get a good heat transfer from the solder wand. Hope this helps. If the wand will heat then the tip should.

SOURCE: The tip of my weller

This happens quite frequently. On the tip there are two nuts that hold the tip to the gun. Tighten them a bit. The tip is made of copper and as this heats, it causes the connection where the nuts are to become a higher resistance and thus lower heat. When you tighten them, it "cuts" through the copper oxidation (caused by the heat) and lowers the resistance, hence more heat.

SOURCE: iron will not heat---could it

If the iron is not getting hot at all then the tip is not the issue. I would goto a local hardware store like home depot or lowes and buy a replacement wall plug. You should first cut, strip back the wires and replace the plug as per its instructions. If the Iron still doesn't heat up after this you should unplug it and dissemble the body of it, you have to unscrew the 3 screws on the top and slide the body down. There will be wire nut connections for the electronics from the wall plug cable to the actual iron, check that they are connected properly. Often there is a break in the pinch point of the cable at the end of the irons body. For solving this I like to cut the wire below the pinch point, strip the wires back and redo fresh connections at the wire nuts. Good luck!

Hello all. I just began having a problem with my Weller WD1 Soldering Station. It powers on fine and the display works, however no matter what temperature the display says it is set to it will not hea

You might want to check the iron itself with an induction power tester to see if it is getting any power to the tip. This type of tester doesn't require any dis-assembly just close proximity to energized circuits.

Misplaced Manual, what butane container to get.

Any butane will work, but the big name-brands are usually filtered better and less likely to cause problems. The biggest issue is the nozzle -- there are a lot of different sizes. Any Weller butane can will fit perfectly (usually cheapest at the local Sears store), but any can with multiple adapters will also work.

If you have an old can that fits, save the nozzle when it's empty. It should fit a different can if you can't find a can that fits the tool.

My Pyropen will not ignite

Not enough information. That's an extremely vague description of the problem. There's no way to suggest a fix without knowing more about it.

Does it spark?
Does butane come out of it?
Is the cylinder full?
Do the switches move properly?
How old is it? How much use has it seen?
Is it an intermittent problem, or constant?

Hi i have an old weller soldering iron and it wont light up, do i have to have the 2 slide controls in a certain position

A soldering iron is composed of a heated metal tip and an insulated handle. Heating is often achieved electrically, by passing an electric current (supplied through an electrical cord or battery cables) through the resistive material of a heating element. Another heating method includes combustion of a suitable gas, which can either be delivered through a tank mounted on the iron (flameless), or through an external flame.

Cant light the thing !!

the one i have, first see if you have fuel in it, if it is full, then check to see that the switch is in the on position, when i put mine in on, it clicks, then it gets hot, also check to see if you have it wide open

My Weller pyropen does not ignite all of the time despite it having gas and a really good spark from the igniter. Is this a common problem and if so how do i resolve it It will also turn itself off if you...

I have the same issue. I overcame it by replacing the tip with a new one. I estimate I get about a year from a tip. I cannot tell why the old tips make the pyropen hard to ignite.
