Attention! This product uses a tip that is no longer manufactured. I have this device and while it does the job I bought it for (simple soldering wires), the tips burn out very, very quickly and need to be replaced after only 20 or 30 minutes of use. I've spent a long time searching online for replacement tips and the new tips advertised for the 7200 do not fit this version of the 7200. This version requires a hex key to change the tips and the new tips have a hex head. screw tip. NOT SUITABLEβ¦
