Can anyone explain how to get an accurate amperage reading off a new Millermatic 350P? We've put an amprobe around the lead while the welder is welding, we've used volt/amp meter at the terminals and same issue. We're getting readings from 20-50 amps and we know that just isn't the case. Are there some sort of power factors or multipliers we are supposed to be using? For FCAW we should be somewhere in the neighborhood of 200-230A at least. ?? Any suggestions on what we're doing wrong?
