B. Remote Voltage Sensing Leads Placement Guidelines For A Single Arc (Required)

Ref. 804 108-A

BEST

Sense leads are out of the current

paths.
Sense leads detect arc voltage ac-

curately.
Best starts, arcs and most reliable

results.

BAD

Sense lead is affected by weld

current.
Due to voltage drops across work

piece, arc voltage may be low,

causing need for deviation from

standard procedures.
