PH-2L and PH-4L stud welding guns with drawn arc & ceramic ferrule
The PH-2L and PH-4L stud welding guns can be equipped for drawn arc welding with
ceramic ferrule when studs with a diameter of 6 mm and more (preferably from 8 mm
on) are welded.
As a rule, welding studs without flange of 6 - 16 mm in diameter are welded on with this
welding process.
To ensure the formation of a weld bead, each stud needs a ceramic ferrule matching its
diameter and shape. The ceramic ferrule must be knocked off and replaced by a new
one after each welding process. See also chapter
technology with ceramic ferrules
For this you also need:
•
Support for ceramic ferrule (see chapter
“15.1 Spare and conversion parts for
drawn arc welding with ceramic ferrules
•
Drawn arc stud chuck (see chapter
“7.2 Drawn arc stud chucks“ on page 31.
Support for drawn arc stud welding with ceramic ferrule
Depending on the scope of delivery, your stud welding
gun is already equipped with a support for ceramic
ferrules.
PH-2L and PH-4L support for ceramic ferrules
If you are unsure about optional equipment/accessories, please contact your
responsible field service or contact us directly at [email protected].
Ensure a minimum stud length when welding with ceramic ferrules. Minimum
stud length = Height of ceramic f 15 mm, e.g. ceramic ferrule for MR10
weld stud = 10 mm high + 15 mm = minimum stud length of 25 mm.
