Appendix A / Adjustment of short-cycle drawn arc stud welding guns
How to adjust the depth of immersion:
• Insert the relevant stud (3) into stud holder until stop.
• Loosen both Allen screws (item 2, chapter 2.2).
• Move support legs (item 1, chapter 2.2) until the required depth of immersion is
obtained.

The bores used for mounting the support legs to the foot plate are long holes which
allow you to lead through the gas supply hose when welding with shielding gas.
