Hope this is the right place to ask - maybe someone will put me right if not. I have a Clarke 151TE which has chassis earth connected to the 240v supply earth as one might expect. The welding "earth" cable is not connected to chassis earth which appears to be a deliberate design point. I want to provide a meatier welding earth connection with a sensible Dinse connector on the front panel. I guess I should use an insulated Dinse socket to respect this arrangement - BUT most seem to be a simple clamp (back threaded conducting element is also the fixing). A larger insulated item would clearly require a much bigger hole in the front panel and guiess what, it's right in the corner. So what is current :-( thinking about allowing welding "earth" to be connected to the chassis via the front panel ?
