Magnetic blowing effect:
•
Deviation of the arc as a result of the influence of magnetic or electromagnetic
fields.
The possibilities of reducing the thermal blowing effect are limited. They are
restricted to precise centering of the stud and chuck.
Several remedial measures are available to reduce the consequences of the
magnetic blowing effect-some of which are indicated below.

Remedial Measures
In order to favorably influence the arc, the earth
terminals must be placed as symmetrically as possible
to the point of welding.
In the event of a one-sided earth terminal the arc blows
away from the terminal. The condition can be
eliminated by additional metal plates.
Influences upon the arc as a result of welding cable
itself can largely be avoided by turning the weld gun
through 90°.
When welding sections, arc blowing can be reduced by
repositioning the earth terminal and additional metal
plates.
