To favourably influence the arc, the
earth clamps must be arranged as
symmetrically as possible at the
welding location.
Influences on the arc by the
welding cable can largely be
prevented by turning the welding
gun 90°.
With a one-sided earth clamp, the arc
blows away from the clamp. This
situation can be eliminated with
additional metal plates.
When welding profiles, the arc blow can
be reduced by placement of the earth
clamp and additional metal plates.
Note:
The polarity in the illustration relates to ferromagnetic materials. When
welding aluminium, the opposite polarity must be ensured!
