Stud holder for drawn arc operation

The PH-2L, PH-4L and PH-5L stud welding guns can be equipped with a stud holder
for drawn arc operation when studs with a diameter of more than 6 mm are to be
welded.
The stud holder is directly screwed on the retaining screw.
The stud holder (1) must be tightly screwed on the retaining screw (2). When the
screwed connection is not tight enough, these parts could be damaged by scorching
during the welding process.

Ensure a minimum stud length when welding with ceramic ferrules.
Minimum stud length = Height of ceramic ferrule + 15 mm
e.g. ceramic ferrule for MR10 studs =10 mm high + 15 mm =
minimum stud length of 25 mm
NOTE
Check after installation that the stud holder is tightly screwed. There is a risk
of scorching during the welding process when the stud holder is screwed to
loosely.
