Arc #2

BAD

Current flow from Arc #1 affects sense lead #2

Current flow from Arc #2 affects sense lead #1

Neither sense lead picks up the correct work voltage, causing starting and welding arc instability.

BETTER

Sense #1 is only affected by weld current from Arc #1

Sense #2 is only affected by weld current from Arc #2

Due to voltage drops across work piece, Arc voltage may be low, causing need for deviation from standard procedures.

BEST

Both Sense leads are out of the current paths.

Both Sense leads detect arc voltage accurately.

No voltage drop between Arc and Sense lead.

Best starts, best arcs, most reliable results.
