Used Miller Polarity Reversing Switch #043942

A proper weld should have a uniform penetration depth and bead shape. At times, this requires accessories or other equipment to ensure that regardless of the metal or electrode you achieve this. Miller makes the Polarity Reversing Switch (043942) to change or isolate the polarity from AC to DC (or vice versa) within the Miller Big Blue 400 or 500 diesel welding generator. This switch allows you to get past restrictions based upon the polarity of your welder's electrode.

Gently used welding equipment sold here at The Welders Supply Company to save you money.
