Sorry bout that......omg! I understand now the problem is the duty cycle, thats the brain block I was having. I guess after tying to decifer it myself, knowing what i was trying to say. I was thinking duty cycle was a power factor at a certain voltage, not pulse duration....... the equiptment I use the duty cycle is rated as the lower the power, the higher the duty cycle, and the higher the amperage, the less the duty cycle. If that makes some sort of sense? (or time on/ time off) but amperage influences the duty cycle, which is not the case for his problem. thanks for trying to explain it to me, yes English is, but communication, not so much.
