WARNING
DANGER
An alternative braided shield connection is provided on the
torch. The female fast-on connection (normally in the arc
starter box) can instead be mated to a male fast-on connec-
tion taped to one of the power cables a few inches before
the end of the torch sleeving. Push the sleeving and large
brass nut towards the head of the torch to reveal this con-
nection. When this connection is made, the shield connec-
tion is grounded through the large brass nut.
