6.2.1 Settings data for drawn arc process
The weld parameters Current and Time indicated in the following table are based on
the recommendations in DVS information sheet 0902. These parameters relate to the
standard equipment of the welding system and welding in tub position on blank, de-
oiled surfaces.

Rule of thumb for drawn arc process:
• Weld current I [A] ≈ 80 × Weld Ø [mm]
• Weld time t [ms] ≈ 40 × Weld Ø [mm]
Fluctuations in sheet metal thickness and properties or changed work conditions,
longer welding cables or heavily loaded power grids make the true values slightly differ
from the settings data. This also applies when welding in forced positions, such as
vertically on the wall or welding overhead. Therefore, before starting work, you should
check the settings with test welds.
