The gun is equipped with a lifting magnet. Before welding, the stud is lifted by the lifting
magnet and automatically lowered again for welding. The height of the lift is also a
decisive factor for the welding result.
The lift height can be determined via the drop time using the stud welding device. See
chapter
“11.1.5 Setting the lift height (drop time) in the "Setup" mode” on page 67.
The lift height is set using the adjustment wheel (f) on the gun.
