Which of the following is NOT a fix to arc blow?

Increasing the current (amperage) is not a fix for arc blow because doing so can actually exacerbate the problem rather than eliminate it. Arc blow occurs when the arc is deflected away from the workpiece due to magnetic fields, often created by the welding current itself or external fields. Instead of increasing the current, which may intensify the magnetic effects leading to more arc instability, it is more effective to address the cause of arc blow directly.

Changing the electrode type, for instance, can help if a different electrode might provide better directional stability for the arc in the presence of magnetic interference. Adjusting the work clamp position can help to minimize the impact of magnetic fields on the welding arc, allowing for better control over the arc path. Additionally, using a magnetic field in a controlled manner can help to mitigate the effects of arc blow by steering the arc in the desired direction.
