If you teardown before these type of cheapo solder iron you will know there is no thermal cut off switch.

i think most soldering iron is cina made...just choose more expensive 1, around rm100 will get you good quality....if you use cheapo 1...u solder till sienz

Not normal at all. Not mere soldering iron, but the whole product retarded. Throw away for scrap metal better before it explodes in your face. Invest more in a regulated soldering iron which should last a life time without such nonsense. RM200+- should be good enough

cheap soldering iron is meant for 1 off use only.

if u bought the cheap ones then just faham faham la. its meant for 1 off use

get hakko if you can afford it, or goot (shopee KS-30R RM 40~) both are made in japan.

get a good one from Pudu
