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
Hi Bart,
Aren't high power resistive elements usually high-R wire, possibly on
ceramic form, and therefore fail open rather than short out?
