OPERATION

In Pulse processes:

The wave control adjustment allows the frequency setting to vary. Increasing the wave control allows the frequency setting to increase, and decreasing the wave control allows the frequency setting to decrease. Varying the wave control setting affects the droplet trans-fer and allows fine-tuning for different welding positions.

In Stick processes:

The wave control adjusts the arc force. Increasing the wave control setting increases the arc force, making the arc more harsh but less likely to stick. Decreasing the wave control setting decreases the arc force, making the arc softer and smoother.

In GMAW and FCAW processes:

The wave control adjusts the inductance. (Inductance is inversely proportional to pinch.) Increasing the wave control setting decreases the inductance, which results in the arc getting colder and pinched tighter. Decreasing the wave control setting increases the induc-tance, which results in the arc getting wider.
