Table 3: Effect of magnetic arc blow and a few possible remedial actions.
Note: The arc blow is proportional to current intensity and may be influenced by connecting the ground terminals in
a symmetrical fashion or by mass balance weight (in the case of manual grippers with an external welding cable by
the rotation of the gripper around the vertical axis; this generates melting on one side and might increase the number
of pores in the welded materials. Table 2 - N° 4).
