[MW:1877] Re:

As per me, Welding in Magnetic Fields will give rise to arc-blow
problems. You will end-up with a weld metal having slag (if welded
with SMAW), Porosities and Lack of Fusion.

To counter this, we should be careful about
1. Welding currents on higher side
2. Arc length to be minimum
3. Welding Polarity - AC with higher frequency
4. Positioning of Earthing lugs

Basic idea to keep the higher energy arc with least possible spread of
arc so that we can get higher arc density and arc force.

Regards.
