Re: [TCML] pig Jacobs

Hi David,
Well, 50A is pretty high for a simple jacobs ladder. Putting the element in a cool bath is a good idea. The pig isn't what will fry. In the worst case scenario, the element will fail and remove the primary limiting device. In that case, the only limiting is the arc impedance itself. You would recognize this by a big change in the arc (brighter, hotter, faster). The breaker may not trip, so if you recognize any change, shut down the pig yourself. 

Take care,
Bart

Thanks,....the resistor is just a small section of an element (i think from an electric dryer ), 12" -14" long, but placed in a 5 gal bucket of water for cooling,......I didnt wanna fry da pig, but they are pretty rugged ,...a 50 amp breaker should be ok ?
thanks,dave
