I'm at a loss for understanding the design of the trigger action of the Weller dual temperature solder gun. In order to obtain the highest temperature, one must pull the trigger half way. To obtain the lowest temperature, one must fully pull the trigger. This seems in reverse to normal human behavior. Does anyone know why Weller designed it this way?

 

Just to make it difficult to remember!

First guess:
They figured that most people are more prone to just go full squeeze on a trigger (potentially not even realizing there is a half setting) so logic would say to set that for the "safer/lower power" setting to prevent most people from overheating everything..
Most people don't need to be running a soldering device at max..

Thanks mcgyvr, that sounds believable. Apparently the company that makes this item just don't trust its customers.

 

It could just be to avoid the normal intuitive action of switching it on full with a full-on pull.
Preventing accidental overheat of component etc.

Thats not really a bad thing.. and of course all assumptions as I didn't design it..

But
Always best to fall on the "idiot proof" side.. The world is full of far more idiots than not..

By guess is someone wired the switch incorrectly. Mine doesn't work that way.

 

I don;t remember mine working that way either.

I haven't used mine in years. I know I had a plastic knife and smoothing thingy with one of them, but I'm not sure if it was the Weller. The other one I remember was a Wen.

My old, as in my fathers 50 year old is two stage with low to high but the newer Weller 550 Model soldering gun:

• Professional heavy-duty gun
• Dual-heat wattage gun
• Fingertip trigger selects high (1st trigger position) or low output (2nd trigger position)
• Fingertip trigger selects high (1st trigger position)
• Or low output (2nd trigger position)
• Heavy gauge, high efficiency, tin-plated copper tip
• Twin lights illuminate work
• 2-wire cord
• UL and cUL listed

Apparently I never got the memo from Weller? Nobody tells me anything!

Mine is about 35 years old and only has two settings. On or Off.

All the Wellers I have owned have had the first pull full-on.
It is in the instructions!

Here you go.

Brain cells must have died. This https://www.galco.com/techdoc/welr/8200_cp.pdf says the same. I own the 2nd iron on the page. I bough the third iron on the page for work. Both were nice.

I love my butane iron for the stuff that needs to be hot.

I do think the high/low pos #1, #2 makes good sense though,

 

Apparently Weller has two different styles of operation.
Here is the instruction for Weller 8200 Soldering Gun. Every Weller gun I have used works this way.
