3.
Screw the collet body into the torch body until hand tight. The electrode
will still move freely.
4.
Screw the back cap onto the torch body, but do not tighten yet.
5.
Screw the ceramic cup onto the torch body. The number on the cup is
the inner diameter of the cup in 16th of an inch. Example 7 = 7/16 in.
6.
Adjust the electrode length so it extends beyond the cup. The maximum
length is equal to the cup's inner diameter.
7.
Brace the electrode and tighten the back cap. This will pinch the collet
and hold the electrode in place.
