10 Preparing Workplace and Welding Process
Warning of electromagnetic elds
Ensure that there is no equipment or apparatus in the working area that
could be damaged by magnetic elds.
Remove if necessary.
Danger!
Ensure that there is a free circulation of air through the housing of the
stud welding unit.
Always place the stud welding unit on a stable, level and clean surface.
Check the condition of all cables and cable connections.
Have defective cables or their connections immediately repaired or repla-
ced by a qualied electrician.
10.1 Preparing Surfaces
Remove
– Paint, oil and other impurities,
– Rust,
– Non-conductive coatings (of surface-coated materials)
from the welding surface and the contact points of the ground clamps.
This ensures a high strength of the welded joints.
Weld the welding element only to a at surface.
Ask your application consultant at HBS about welded joints on tubes and rife
plates (see page 2).
