Yihua 899D-II Rework Station: Unboxing & First impressions

[@javiergil8114]

@whcvip Hello, thanks for the first impressions, I recently purchased this soldering station. When I turn on the soldering station, I always hear a small noise like an electrical hum, I think it comes from the transformer, also the sound makes the case vibrate very slightly when I touch it (like a tingling). It is normal?

Maybe the core of the transformer is broken or loose

Thanks 👍 I wasn't sure if this brand is well known or not...now i know, also is that 700w?
