My near new Diversion is a 72%EN or 28% EP, with square wave
I bought a Dialarc 250 HF with water TIG. It being a transformer machine I think AC balance is 50%, with sine wave. It is said to be "high frequancy", though I don't know how high that is. Shouldn't this mean more cleaning action? It doesn't seem to be the case. Is this normal? Can it be fixed?
