Question 1

What is that tool that looks like a fork used for? ( I'ts a black handle w/ screw and a u-shaped piece of wire)

Accepted Answer

Dear Rocco,

Thank you for your question.

The IC extractor, i.e. the fork-like tool, can assist with the de-soldering/removal of ICs.

How to use:
when concentrating hot air to the soldered chip, you can wedge both tips of the extractor in to lift the IC easily. This helps avoid damaging the IC.

Should you have any questions, please feel free to contact us.
Best regards,

Question 2

Can this equipment work with 220V input power supply?

Accepted Answer

The purpose of a transformer is to change input voltage to output voltage. Someone commented on the transformer and may not have l8ojed at the input value but saw the output value instead. Their products are genuinely compatible with with 240v. The unusual part of that person's reply was that the transformer was rated at 50 Hz, which would not work in the USA, and I a confirm it works over here. However, Europe works on 50 Hz and several countries work on 240 volts which would require a transformer to turn it into 120v at 50 Hz

Question 3

Dose it have a cooling fan in back?

Accepted Answer

Dear customer,

This YIHUA 853D 2A USB rework station comes with the smart excessive temperature protection function. We confirm that there is a cooling fan in the back. The fan will be activated automatically to protect its internal parts if the temperature should exceed the safety temperature.

Feel free to contact us if you should have any questions.

Thank you and best regards,

Question 4

Where is the pump locking bolt located at the bottom of the unit? The manual has no picture for point of reference.

Accepted Answer

Dear Customer,
Thank you for getting in touch with us.

The rework station of the YIHUA 853D 2A USB delivers smooth air by a brushless fan instead of a pump motor. Air delivery type is stated in the Specification section on the product page. (https://www.amazon.com/gp/product/B07S4GPM66)

We assume the caution of removing the locking bolt is for other models containing a pump motor and is not for the YIHUA 853D 2A USB. (No locking bolt needs to be removed from the YIHUA 853D 2A USB upon the first use).

Thank you for bringing this to our attention and we are sorry for the confusion.

Please feel free to get in touch with us via Amazon’s Messaging System (link is here: https://amzn.to/2mKq0EU) if you’d like to have a digital copy of the latest Operation Instruction for the YIHUA 853D 2A USB.
