Hakko 907 Clone with silicone handle (Fakko 907) E-bay

[rustybronco]

I purchased a Fakko 907 with 'silica' handle off E-bay for $9.98 USD shipped.

Before purchasing it I contacted the seller to see if this 'better' one also included a silicone cable as it is called in the listing. I receive it yesterday and it does in fact come with a silicone (read heat resistant) cable. The cord is 36  inches from the 5 pin DIN connector to the strain relief at the handle. The grip is far as I can tell silicone as well but I am not a chemist so take this a speculation on my part.

The heating element on this device reads 3.1 ohms and the sensor reads approximately 38.5* ohms if I remember correctly. (The heating element reading of 44.7 ohm is within specs on a subsequent measurement.)

The handle appears to be of acceptable quality although the tip leaves a lot to be desired. It didn't want to take solder readily and the hole where the heating element inserts is slightly off center body making the metal portion of the handle tip down wards. Rotating the tip in the sleeve will correct the issue as will filing the end. A real T18 or 900M tip should solve it permanently. I would suggest you use the factory tips if at all possible.
 
For $9.98 USD plus the price for a real Hakko tip and you get a reasonable facsimile of the Hakko 907 for a getting harder to find at a reasonable price iron that even fits the standard iron holder. Even less if the silicone cord and grip don't really matter to you.

*Correction... the sensor reads 44.7 ohms. I must have had a poor connection when I initially checked.

907 is obsolete,
get a t12 based iron like a bakon 950d

[rustybronco]

Not for those of us still using a 5 pin connector like used on Hakko 926 and 936 series stations.

If someone is building a DIY soldering station or has a unit that uses the T12 handle then yes, that suggestion may be relevant.

I have a 937D+ clone soldering station.  Does anyone know if this iron would work  with this unit. It  is fitted with the 5 pin Din socket. The cable is a bit short, those extra few inches would help.

Thanks

There are ones available with the 937+ style connector but why not just replace your iron's 
cable with a longer one such as this? https://www.aliexpress.com/item/High-temperature-three-core-silicone-wire-manufacturers-accusing-handle-T12-line-DIY-soldering-station-handle-line/32488916226.html?ws_ab_test=searchweb0_0,searchweb201602_2_10065_10130_10068_433_434_10136_10137_10138_10060_10062_10056_10055_10054_302_10059_10099_10103_10102_10096_10052_10053_10050_10107_10051_10106_10084_10083_10080_10082_10081_10110_10111_10112_10113_10114_10078_10079_10073_10070_10122_10123_10126_10124,searchweb201603_2,afswitch_1,ppcSwitch_5,single_sort_0_default&btsid=2a49173b-5a45-42e7-af64-f143fba0a3d5&algo_expid=8d1f0678-faa3-492a-b2b7-3ad710681ffc-34&algo_pvid=8d1f0678-faa3-492a-b2b7-3ad710681ffc

In addition to the differing connector style, you need to measure the resistances of your handle to make sure its compatible with the Fakko 907 variant.

Is this the style end on yours?

Yes. That's the end that's fitted on my cable.  I wasn't aware that you could get longer cables, thanks for that info.  Is there a pinout diagram I could use  to identify the heating and sensor elements on the iron?

[rustybronco]

I suppose in the back of the manual for it there is. The Hakko 936 lists the pinout.

Problem with silicone, depending on formulation is that it can stretch out of form from repeated squeezing or be brittle and fall apart chunk like.
