IMPORTANT! In the Standard / Pulsed arc combination, only weld the leading
wire electrode in the spray arc.
Possible uses, The Standard / Pulsed arc combination is used for steel applications with thicker
area of applicati- sheets.

Large seam cross-sections are possible
Big differences are possible between the two wirefeed speeds
The pulsed arc of the trailing wire electrode then achieves visually attractive
weld seams
