[Alda H-30T] An unexpected but still perfect soldering iron [Copy link]

 

Once unpacked:

I have to say that this delivery was a bit unexpected. I haven't shopped online recently, but I suddenly received a delivery. I opened it and found out that it was the Alda H-30T soldering iron that I applied for on the forum.

The outer packaging box introduces some parameters of the soldering iron on the market, mainly the power consumption.

Inside is the soldering iron + warranty card. The heating element of a soldering iron is still very fragile. The packaging is a bit thin, with only a paper box and no other protection. It is not safe for violent transportation by express delivery. The warranty card also has instructions for replacing the soldering iron tip. (I don’t know if the package sold includes a soldering iron stand. People who use it for the first time may lack a soldering iron stand).

2. Workmanship

First of all, the appearance. This is the first time I have seen a soldering iron with this kind of design . There are some information + temperature knobs on the front of the controller, and a power indicator light on the back, which is green. Except for the top part of the power cord, the material of the soldering iron from the controller to the soldering iron is soft silicone wire (it seems to be high temperature, because the soldering iron tip touched it and it didn't melt). The overall texture and feel of the soldering iron are good.

The H-30T also comes with a knob cap, which is a bit disappointing . First, the surface is not polished enough; second, the size is not suitable and is slightly too large:

After putting on the knob cap, most of the scales are covered, leaving only the 200, 400, and 600 fonts. In addition, the knob cap or the scales are not standard circles, causing the covered scales to fluctuate when the knob cap is rotated, and the offset process is clearly visible.

3. Power consumption when starting up

Although I really want to take it apart to see the internal structure, after all, it is a review, so I will wait until the review is finished. Turn on the power, connect it to the power socket, and see the power-on process of the soldering iron

When the machine is turned on and heating up, it is basically 32 to 46W. After the temperature stabilizes, it basically maintains around 20W. This power consumption is indeed very low, even lower than advertised.

4. Low temperature standby power consumption

In addition to the normal power consumption shown above, the Alda H-30T soldering iron has two other modes, one is low temperature standby mode and the other is hibernation mode. The video above tests the power consumption in low temperature standby mode, which is basically maintained below 12W . This function is definitely very energy-saving. The soldering irons I used before were generally larger (soldering stations) that had hibernation functions.

4. Tin melting test

(In order to avoid residual heat interference, each test is separated by more than 20 minutes, and a new test is started when the soldering iron has no residual heat)

Comparison of 3 soldering iron melting speeds:

I have three other soldering irons on hand, one yellow one (which has been my main soldering iron since I started working) and two antiques (one I bought in high school and one I bought in college. The common point is that they are both external heating types, and I only thought about the cheap price at that time ).

Comparison of the tin melting time of H-30T, Huanghua and Xinwei soldering irons:

During the test, the temperature was set to 300 degrees, and the solder wire used was as follows:

Uh... H-30T is the fastest in tin melting: 23s, Huanghua 32s, Xinwei 1m20s. I originally thought Huanghua would be the fastest.

Well, let's test the melting time of H-30T at a maximum temperature of 600 degrees:

1 5s ... This speed is really unexpected. It is really fast.

Five: Sleep test

First attach the complete dormancy test video:

The video is a bit long, more than five minutes. From this process, we can understand that the sleep and low-temperature standby of H-30T is a cyclic process. It is speculated that it is to ensure the minimum waiting time for welding while consuming power. Therefore, there is a sleep tin melting test later.

6: Sleep interrupt test

After being left on the soldering iron stand for a period of time, it will enter standby mode. At this time, using melted solder wire will not interrupt the standby mode. It will only exit standby mode after being picked up.

7: Temperature test during sleep and standby

It is measured that the solder wire is still very easy to melt in standby mode. Only after a period of dormancy at 1.1W will the temperature drop. This means that in this mode, the heating core should have stopped supplying power.

Summarize:

The Alda H-30T high temperature dormant version of the constant temperature soldering iron gives people a good feeling in terms of feel and material. At such a fast melting temperature, the power consumption is also well controlled. However, the subtle workmanship can be improved.

There are two other points that may not be shared by everyone:

1: Add an on/off key to cut off the power of the entire soldering iron without plugging in or unplugging the power supply;

2: Move the power indicator light and the knob to one side. Now they are on two opposite sides, which is not very intuitive to look at.

OP, you are acting like you can get a review for this post?!

wangerxian

The review is quite detailed. Did you buy a soldering iron in high school?

How many more posts do I have to write?

There is also a pointer multimeter

Pointer multimeter, I did use it in high school~haha

Only that blue earthen branding iron can show its power!

Technology makes people lazy, and now I don’t know how to use it anymore

I used to use it to weld things and drill holes in buckets at home.

Technology does make people think less.

Thank you! You've worked hard. I want to download a video, but it won't work.

ardtek

By the way, the efficiency of the split universal soldering iron tip has been brought to a near-limit. Any objections?

ardtek

Let me say something from the bottom of my heart - usually the portable design is for the convenience of carrying, but in the end you get a product with unsatisfactory performance or even nothing at all.

But Alda is definitely not. Alda's portability is more powerful and efficient than non-portability. Thank you very much!

Thank you all!!!
