DESCRIPTION
This
unit
is
a
Digital
Voltage
Control
that
is
designed
to
be
used with
a
constant
potential
welding
power
source
and
digital
control/feeder
for
Gas
Metal-Arc
Welding
(GMAW).
With
this
control,
the
welding
power
source
output
voltage
may
be
preset
before
the
arc
is
struck.
This
preset
voltage
will
be
maintained
during
welding
even
in
the
.)resence
of
line
and
load
variations
within
the
capability
of
the
welding
power
source.
