welding voltage into plc
(OP)
Is it possible to step down electrode to ground potential for use as an analog input? Welder is ~70ocv and ~40ov.
Be gentle

RE: welding voltage into plc
However anaother problem occurs with many welders. The output is not filtered, so has considerable ripple. This will affect the noise in your analog signal.
Another problem is that many welders use a inductor in series with the output. This will cause very high voltage surges when used as a welder.

I ask this for there may be alternatives. Maybe current draw would be better then would know when the welder was in use.
As far as measuring voltage a PT (Potential Transformer) of adequate size should work.
