4-1. Description

This unit has two CC/CV modules with separate weld controls for applications where two welding arcs are needed. A
Welder Selector switch controls whether one or both sets of weld output terminals are active (see Section 6-2). When
the unit is operated in the dual operator mode, each welder has CC and CV weld output available for Stick, TIG, and
MIG welding. When in the single operator mode, CC weld output is available to the welder on the Welder B (right) side
only (CV not active in single operator mode).
