DC amps to AC amps?

admin

If you are using a rod for AC or DC, and someone recommends a current for one setting, is it the same for the other? I instinctively want to say that AC current should be DC value multiplied by the square root of two, and that if you are given the AC value, you should divide by the square root of two for the proper DC value....but somehow, I get the impression that it's not nearly that simple."To tell which polarity to use go to the bathroom and pour some water down the drain. If it runs clockwise use straight polarity. If it runs counter-clockwise use reverse polarity. Or if it just gurgles use alternating current." -RandomDave
Reply:Lincoln says add 10% for AC.David Real world weldin.  When I grow up I want to be a tig weldor.
Reply:Just try the rod on each current. You'll figure it out pretty quick. David told you right.
Reply:That certainly makes the math easier. "To tell which polarity to use go to the bathroom and pour some water down the drain. If it runs clockwise use straight polarity. If it runs counter-clockwise use reverse polarity. Or if it just gurgles use alternating current." -RandomDave
