• ARC CONTROL

Also known as Inductance or Wave Control. Allows operator to vary the arc characteristics from "soft" to "harsh" in all weld modes. It is adjustable from -10.0 to +10.0, with a nominal setting of 00.0 (The nominal set- ting of 00.0 may be displayed as OFF on some Power Feed wire feeder control panels). See the Welding Mode descriptions, below, for detailed explanations of how the Arc Control affects each mode.

CONSTANT VOLTAGE WELDING

Synergic CV:

For each wire feed speed, a corresponding voltage is preprogrammed into the machine through special soft- ware at the factory. The nominal preprogrammed volt- age is the best average voltage for a given wire feed speed, but may be adjusted to preference. When the wire feed speed changes, the POWER WAVE® auto- matically adjusts the voltage level correspondingly to maintain similar arc characteristics throughout the WFS range.

Non Synergic CV:

This type of CV mode behaves more like a conven- tional CV power source. Voltage and WFS are inde- pendent adjustments. Therefore to maintain the arc characteristics, the operator must adjust the voltage to compensate for any changes made to the WFS.

All CV Modes:

Arc Control, often referred to as wave control, adjusts the inductance of the wave shape. The wave control adjustment is similar to the "pinch" function in that it is inversely proportional to inductance. Therefore, increasing wave control greater than 0.0 results in a harsher, colder arc while decreasing the wave control to less than 0.0 provides a softer, hotter arc.
