hooking up an arc welder




From: Cabbott Sanders <cabbott-at-cyberis-dot-net>

Im glad charles brush told me how to hook up that arc welder. THANKS CHARLES!!

it may seem AMAZING, but i almost fired it up, with the SECONDARY terminals of
the arc welder in series with the 15 KVA PIG!!  I'm glad i didnt do this..
'coulda started a fire!! (?)
