Hello, knowing that here are some experienced Weller insiders around here is my question concerning the grounding of the tip of these two stations. Since 18 years I have been using my WTCP-S (Magnastat) with its jack for grounding of the tip at the front panel of the station. This jack and other ESD items (wrist band etc.) I normally connect to a standard ESD plug equipped with a 1 MOhm resistor to the (yellow/green here in DL) ground (Schutzleiter) of our 220V~ supply. Now I had to replace the heating element of the WTCP-S and soon after that the switch within the iron itself needs to be replaced. OK -- I think I'll replace the switch too but to have a second iron available I found the WTCP 51 station which seems to be the successor type using the same tips and iron. Having good experiences with Weller and not enough money to buy stations of JBS or even Metcall I want to stay with them.
The tip is no longer connected to a front panel jack but directly to the now three wire (two wires here at the power supply of the WTCP-S) mains connection's ground of the WTCP 51 station. The question is: Is it better to insert a 1 MOhm resistor within the station enclosure instead of this "hard" grounding? But perhaps "Weller" had a good idea when connecting the tip directly to ground and I only don't know it.
