WELDING MODE DESCRIPTIONS
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 corre-
sponding voltage.
Wave control adjusts the inductance of the wave
shape. (This adjustment is often referred to as "pinch".
Inductance is inversely proportional to pinch.) In-
creasing wave control greater than 0 results in a harsh-
er, colder arc, while decreasing the wave control to less
than 0 provides a softer, hotter arc. (See Figure B.2.)
