Welder Current Measurement
Welder Current Measurement
(OP)
I am trying to measure the current on an Meibach Welder at our plant. The welder is used to weld stainless steel coils of max width 1500mm and gauge 2mm. The welder operates intermittently and current values vary across a wide range. I do not know what the exact current values are and what the range is. I was thinking of using a ct to directly measure the current, however this may prove a bit costly, and space constraints prevents this solution. My other idea was to use a shunt and measure volt drop across it and then calculate a current in my plc.
Any comments?

Pretty simple.

Thanks David

The only caveat is the coupling coefficient for the current probe. If the current is indeed that high, you might need to "roll" your own current probe, but building a less efficiently coupled clamp, either through a bigger gap between the conductor and the coil or a skinnier coil.
