24. DS/ January 2004 Benefits with VirtualArc® giving you cost savings  Daily process support in your factory  Shorter process implementation time  Optimised welding productivity  Optimised welding quality  Improved welding procedure documentation

25. DS/ January 2004 From VirtualArc® Customer evaluation  “The major strength of this program is the easiness of performing and fine-tuning welding tests off-line. This means that testing time in the production is reduced to a very low level.”  “The first year of investment the program has paid itself back.”  “Another noteworthy aspect is the easy use. Very quickly, you get familiar with the program.”  “The result from the virtual test is very precise and for the most applications it can be used directly.” Kim Hurup IWE, Invacare EC-Høng, Denmark
