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)
