I'm moving into a new shop in which the electrical service is somewhat limited. I have an Idealarc TIG-250/250, Code 8809 (no suffixes given), Ser. # AC-781769.
Some of these units came with power factor correction, consisting as far as I can tell of a "stabilizing capacitor" (P/N S-10191) and a "stabilizing resister" (P/N S-10404-19). The Lincoln parts blow-ups I've found do not show these components. Where do I look to see if my welder has them? My interest in this is that, as I understand, having the power factor control parts has the effect of damping the amperage surge when the welder is switched on. If so, this might let me get away with a slightly undersized power supply circuit breaker (min. 92A is called for by the specs on the welder for 240VAC; 100A for 208). I never have had reason to run the welder "wide-open" and don't expect to, but some owners of this machine report popping slightly undersized breakers when switching on (while others say they have no such problem).
I understand that there are no NOS parts for this welder. But IF my machine proves not to have the power factor correction circuit, AND if this in fact has any bearing on kicking off breakers, are the specs known for these parts, and could I wire-in a generic capacitor and resistor of the right specs??
And is there a drawing somewhere that shows this circuit or the components?
