BMS-10P year of manufacture) GAP/CONTACT switchover The SK-5AP/KS stud welding head can be switched for gap or contact welding using the adjusting ring on the welding head. A time-consuming conversion or welding head change is therefore no longer necessary. Contact welding is preferably used for stud welding on problematic surfaces.
Connection and installation The stud welding head is already integrated into a SOYER ® stud welding system in the factory. This is the best solution. You are using a perfectly coordinated stud welding system. Observe the following instructions, particularly in combination with a robot or an external handling system (special system).
Pneumatic slide In the following, we explain the assembly using the example of a SOYER pneumatic ® slide with 125 mm lift and a stud welding head. Figure 05: Mounting example with pneumatic slide Item Designation SK-5AP/KS stud welding head...

Page 30
Step 9: Remove the adjusting mandrel and insert a suitable stud chuck and stud feed pipe again, as set out in chapter „7.2 Inserting the stud chuck and stud feed pipe“ from page 39. Alignment is complete. Soyer Bolzenschweißtechnik Operating instructions...
A hose package is not included in the scope of delivery. This must be ordered separately. Tension relief! The quick couplings and connectors are not suitable for tension relief. Ensure sufficient tension relief and secure cable routing for robot applications, for example. Soyer Bolzenschweißtechnik Operating instructions...
If the stud feed hose is used incorrectly, or an unsuitable hose is used, there is a risk of injury due to ejected welding studs. Only use original stud feed hoses from Soyer GmbH. • Only ever use stud feed hoses which match the stud diameter.

The height of lift always depends on the respective stud dimension and welding task. With the SK-5AP and/or SK-5AP/KS stud welding head, the stud must be lifted to a defined height directly before the welding process and lowered again during the welding process.
Check whether there is a stud in the stud chuck. If necessary, reload a stud by pressing the release button (see chapter ”6.10.2 Connections on the SK-5AP and/or SK-5AP/KS stud welding head” on page 36) on the stud welding head.

Setting the height of lift in the setting mode The height of lift must be set for the SK-5AP and/or SK-5AP/KS stud welding head (GAP operating mode). The stud is lifted to a defined height/to a defined time directly before the welding process and automatically lowered again during the welding process.
