Quick TR-1
« on: May 15, 2024, 02:09:34 pm »
Hi all, first time poster so please forgive me if I've bungled any vital forum etiquette.
I couldn't find any reviews and hardly any info about this thing on the English internet, so I thought I'd pick one up and share.

What is it?
The TR-1 is an all in one air gun, no base unit, the handle plugs straight into the wall.
It claims 1000W of heat at 100-550c, and 55L/min flow.

Where can I get one?
I bought mine from China Phonefix (, but it's also on Aliexpress and
I paid £87 plus £14 shipping, it turned up in about a week.
It's available in 220v and 110v variants, mine is a 220v which arrived with an unfused type I plug.

What's inside?
Dissasembly is nice and easy, the plastic guard around the hot end unscrews, and the air inlet the other end twists and pulls off.
This reveals two 6 screws to be removed, then the whole casing splits in two.

The casing is a little thin and flimsy, and there doesn't seem to be much seperating the hot nozzle from it.
It lets down an otherwise fairly solid product I'd say, especially with 220v and an alleged 6A flowing inside.

There's a control board with the buttons,display and an STM32 running the show.
A stacked power board looks to have a rectifier, an enourmous cap, SMPS and driver for the fan motor
The third board appears to handle switching power to the heater.

The fan motor is a mains voltage brushless contraption.
The heater looks to be wire around a ceramic core with some kind of temperature sense down the middle.
Power connections look solid enough, mains earth runs straight through to the nozzle, cable has decent overmoulded strain relief.

What's it like to use?

The controls are straightforward, power button turns on and off, settings button switches between flow and temp, +/- adjusts in 5 degree increments.
Current temperature is displayed normally and set temperature when adjusting.

It's a bit of a handful at 30cm long, but not unmanageable.
The cable is reasonably flexible, and hopefully will loosen up with use.

Nozzles can be hot swapped with a pair of pliers or silicone pad.
It heats quickly, and automatically cools before turning off.
Looking down the nozzle, the heating element visibly pulses red at about 5Hz. Not sure what that's doing for the life of the heater, but the air tempt at the output feels stable.

The noise is more like a laptop fan than a traditional air gun, on low it's nice and quiet and at full whack it's no louder than a hair dryer.

I'm not currently equipped to check calibration, and whether the specs are truthful, but so far I'm impressed.
It's not as nice to use as a proper bench top set up, but for work on the go its more capable than anything I've seen.

I'll update this once I've given it a bit more use, let me know if there's anything you'd like to know or tests you want to see.

Thanks for the photos and review.
It looks good, did you measure power consumption? How heavy does it feel?

Main issue seems to be potential weak plastic where the metal mounts to the unit and long length of the handle, as you say.
Still might be good for heatshrink or as a general purpose precision heatgun.
