OPERATION

B-5

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, colder arc while decreasing the wave control

to less than 0 provides a softer, hotter arc. (See

Figure B.2)
