Arc #2
BAD
flCurrent flow from Arc #1 affects sense lead #2
flCurrent flow from Arc #2 affects sense lead #1
flNeither sense lead picks up the correct work voltage, causing starting and welding arc instability.

BETTER
flSense #1 is only affected by weld current from Arc #1
flSense #2 is only affected by weld current from Arc #2
flDue to voltage drops across work piece, Arc voltage may be low, causing need for deviation from standard procedures.

BEST
flBoth Sense leads are out of the current paths.
flBoth Sense leads detect arc voltage accurately.
flNo voltage drop between Arc and Sense lead.
flBest starts, best arcs, most reliable results.
