Arc Performance

The capabilities of the Power Wave AC/DC 1000™ in a multi-arc environment offer digital control over the critical welding variables for

optimum performance whatever your needs require. As shown below, these digital controls can be used for each arc to provide unprece-

dented arc welding characteristics.

Productivity Comparison

The Power Wave AC/DC 1000 delivers optimized productivity through the ability to adjust phase relationships between the arcs. Multiple

arcs can be tuned to work together rather than interfere with each other.
