High-speed welding
This chapter provides setting information and guideline values for high-speed welding and relates
to the PHOENIX 521 Highspeed machine series only
The following examples apply to mechanical welding. In manual welding, 1mm wire can also be used.
In addition, 92%Ar / 8%CO

or 90%Ar / 5%CO

can be used as the shielding
gas as well, whereby similar results are achieved using the gases 92%Ar/ 8%CO
2
and 90%Ar / 5%CO

.
Under 82%Ar / 18%CO
2
the rotation is poorer and the seam surface becomes rougher.

The greatest seam volume with a virtually concave seam shape was achieved using Argomix 4.
The highest level of fusion performance at high welding speed was achieved using Argomag T.
The spatter formation was the lowest under Argomix 4.
