POWER WAVE 455/R (CE)

CONSTANT VOLTAGE WELDING

For each wire feed speed, a corresponding voltage is
preprogrammed into the machine through special soft-
ware at the factory. The preprogrammed voltage is the
best average voltage for a given wire feed speed.
With synergic programs, when the wire feed speed
changes the Power Wave will automatically adjust the
voltage correspondingly.

Wave control adjusts the inductance of the wave-
shape. (This adjustment is often referred to as "pinch".
Inductance is inversely proportional pinch.) Increasing
wave control greater than 0 results in a harsher, cold-
er arc while decreasing the wave control to less than 0
provides a softer, hotter arc. (See Figure A.5)
