Sorry for the long post but I thought it better to try and explain things in as much detail as possible.
In the image below you can see that on the PCB there are two (4 way) terminals, one is for push/pull gun and the other is for an intermediate feeder.
If I wanted to use an intermediate feeder then I would swap over the connector onto the other terminal. That is all well and fine but it means removing the side and top of the welder, not a massive job but a PITA if doing so on a regular basis. Also the location of the plugs on the PCB is not exactly the easiest to access.
So my thinking was to wire up a 4 pole 2 way switch and have the plugs connected to both terminals on the PCB and have them go to the switch and then from the switch to the plug that then takes the wires to the socket on the front of the welder.
The wiring would have to be about 500mm long as there is really only one place I can fit the switch so I am a bit worried about noise being an issue. In the drawing you can see there is a toroid, which I assume is for noise suppression. So what I am wondering is should I fit 3 toroids (one on each set of wires) or just have the one as per drawing or just a single one as it is now?
Alternatively would I be better using shielded cable and grounding the shield to the earth points in the welder? This is the route I would take in a CNC but a welder is not a CNC
