About the line voltage of soldering iron

In Aug 2022, I ordered one soldering iron through Digikey:

It works great, with the line voltage of 220V in Singapore.

When I try to re-order it today (with the same digital key number), I found the line voltage specified is 110V only.

Q1: For the soldering iron sold in 2022, is it rated at 110V or 220V?

If it is 110-V only, how can I use it in Singapore (220V) directly?

Q2: For the soldering iron currently available, can you help check whether 220V is supported?

Many thanks.

Many thanks. How about the item sold in Aug 2022?
