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 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.
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.
