Making Fillet Welds with Power Wave AC/DC 1000™ System

Now from Lincoln - the power
to increase productivity with
Power Wave technology!

Lincoln Power Wave technology
based upon the new Power Wave
AC/DC 1000™ power source
provides the opportunity to
significantly lower the cost of
making fillet welds and at the
same time, makes many of the
issues that cause weld defects
a thing of the past. In some
respects, the Power Wave AC/DC
1000™ describes both a new
generation of equipment and
a new technology for
controlled welding.

Now, from a single power source
it is possible to choose the very
best type of arc characteristic for
the particular job at hand. The
Power Wave AC/DC 1000™
system allows the choice of the
appropriate voltage-current
relationship at the mere “flick
of a switch”.

CHOICE AT THE “FLICK OF A SWITCH”

• Constant current (sometimes referred to as variable voltage).

• Constant voltage.

• Square Wave AC.

UNLIMITED AC OUTPUT TAILORING

• Choice of AC frequency (from 10 Hz to 100 Hz).

• Wave balance control to allow more or less DC

positive component.

• Offsetting the AC wave to change the magnitude of the

negative or positive component.

REDUCTION IN DEFECTS

• Virtual elimination of arc-striking problems.

• Virtual elimination of arc blow.

LOWER COSTS

• Documented productivity increases over conventional

submerged arc welding.
