The comparative reference voltage changes in accordance with the input voltage-ON duty characteristic curve on the basis of the ON duty of the drive pulse of the switching element.

The duty ratio before and after the polarity inversion of the short-cycle current can be set to an arbitrary value.

The control device (30) uses the determined duty ratio (DR) to provide switching control to the NPN transistors (Q1, Q2).

The PWM output signal includes a duty cycle term corrected for one or more sources of error in the welding system.

All values in both tables were calculated at 60% duty cycle.

Running cycle of the receiver (duty cycle, or operating time per 10-minute cycle).

Most smaller cheaper welding machines have 20% duty cycle.

Example: If the power source operates at a 25% duty cycle, it will provide the rated

Example: If the power source operates at a 40% duty cycle, it will provide the rated

The duty cycle is valid for 40 °C / 104 °F, or below.

150 A @ 60% Duty Cycle For Stick Process (Other Voltages)

The electronic control unit (32) generates a pulse width modulated signal having a duty cycle proportional to the measured amount of applied input torque.
