I recently bought a 3000W pure sine wave inverter from AliExpress hoping to use it for my soldering projects. Unfortunately, it seems like the inverter is delivering too much power to my soldering iron, which has already caused damage to two of them. I'm looking for advice on how to remedy this situation. Is there an adapter or something that can help control the power output?

Where are you located, and what exact inverter and soldering iron are you using? The specs of both devices matter a lot. It's possible that the ratings don’t match up well, which could cause these issues. Honestly, a lot of the cheaper inverters have a reputation for inconsistent outputs and can even spike or drop voltage, which isn’t safe!
I’m a bit confused about what you mean by 'too much power.' Are you seeing a higher voltage than expected? Generally speaking, inverters are supposed to be rated higher than your load, so they shouldn't just push too much power on their own. It's the appliance that uses only what it needs. How are you measuring the output?
If you're having power issues, consider getting a variable power supply. That way, you can adjust the voltage to what your soldering iron requires without risking any damage.
It sounds like you might need a better-quality inverter. Brands like Meanwell or Victron are usually more reliable than what you find on AliExpress. They tend to give steadier outputs and won’t cause damage to your tools. Just a thought!
