Just be wary of this Iron
I have found that this brand of temperature controlled soldering Iron  Dick Smith T2200, that the on/off switch on the front does NOT turn off the mains 240v power but only in the secondary side of things

how did I find this out?  Turn it off and the unit still hums in the mains transformer.
The power light only comes on when the switch is in the On position.

Most electronics do that nowadays. Especially things that can be switched on with a remote (TV's, AV stuff) or a microwave oven. Not really a problem, although personally I still like a switch that switches off the power completely, except for devices which will lose memory settings. They will use 3/5'ths of f-all power nowadays.

I had a CD player years ago where the only thing the power switch did was turn off the display!

I agree, it's of no real concern, got a photo of the inside though?

Aaron, a real b...r to try to get into - I didn't want to strip screw heads, etc

but outside of that, not switching the mains off in not ideal IMO,   yes I know TV remotes etc is a different story.

If I was as concerned as you seem to be I would be taking it apart and joining the secondary away from the switch and routing the mains from the fuse output to the switch and then back to the primary.

If you're not that keen on changing it then obviously you can't be that concerned either.

Just physically unplug from the mains when you want it off, so much safer and simpler than trying to modify a device without qualifications (Aaron you would be obviously capable and qualified)

Pretty sure Sol might be too.

Assuming the switch is mains rated.

I'd be very careful about providing that kind on info to others, you 'may' in fact be breaking the law.

Again I am pretty sure Sol would be able to work that out pretty easily.

really !!!!  my soldering irons don't have a power switch and a few other transformer irons that I have used also don't have power options.

just use your brain. unplug the unit if your not using it. there are a many devices out there that can kill and don't have a mains switch.

I have used a "standard" 25w soldering iron for about 15 years on guitars for repairs and modifications and find it works really well.
I was considering buying a variable output iron years ago but given the quality of the soldering job that a fixed iron produces, I have not bothered.

I can see with electronics and more delicate jobs a variable output would be very beneficial.
