20 Most Recent Weller Portasol Pro Cordless Butane Soldering Iron Kit Questions & Answers

Hi there,

Due to the lack of detail provided, there are certain assumptions that must be made. These assumptions may or may not address the specifics of your problem as described. Please don't take anything I state in a derogatory way.

Standard operations.
These devices use very little fuel, with a single charge lasting about two hours.
After they are warmed up, the only visible evidence they are functioning is the dim red glow at the vents behind the tip.

Firing it up.
I'm assuming it has fuel in it.
When you try to fire it up, I'm assuming it is turned on and you can hear fuel being released.

The Super-pro models have a built-in igniter, otherwise using a lighter or a spark, ignite the gas at the vents behind the tip

A yellow flame can appear for a few moments until the unit heats up. It will quickly subside to a smoldering red glow.

It will take a few minutes for the tip to become hot enough to use.

That is about it,

Best regards

I have the same soldering iron and have found for this problem, the replaceable tip has worn out.All you need to do is buy a replaceable tip of your choice. The tips are a consumable part that wears out.

It is supposed to produce heat there, it's the place where catalytic combustion takes place. If the tip doesn't heat up enough, it means that either the tip is not screwed properly into the housing, or there's not enough gas pressure. The catalytic mesh should be orange in color when heated properly.
Too low gas pressure may be a result of many things, like a malfunctioning valve (regulator and/or on/off),or clogging of the ceramic pressure reductor due to poor quality gas used, with high heavy fraction content.

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.

Sounds like main transformer is bad or bad connection. Unplug it and take it apart and check for loose connections. Good luck.
