Very bad soldering station. The tip is not properly tinned. And the company does NOT have any replacement tips of any kind. I found a way to salvage this bad station, I took it apart and removed the control board. I bought a good Weller SP25 soldering iron and soldered it into the socket. SEE APPENDIX. DO NOT buy this device unless you want to do what I did. It is best to start with a Weller soldering station. I'm not a noob, I've been a Motorola tech for over 30 years. Jim
