IS-444C/471C Features & Benefits<br />
� High-speed inverter-controlled welding power supply with high<br />
capacity IGBT<br />
� Fifteen weld schedules for various applications<br />
� Five control types: Constant power, secondary constant<br />
current RMS, primary constant current PEAK, primary<br />
constant current RMS, and constant phase.Primary<br />
constant current RMS/ Primary constant voltage RMS<br />
� Three monitoring parameters: Power, current, and voltage<br />
� Selectable time scales in ms or cycle<br />
� Selectable control frequency: 600Hz, 800Hz, or 1kHz<br />
� Weld to displacement function<br />
When a weld displacement reaches a certain level the<br />
weld current can be interrupted. This generates a stable<br />
result. For this feature, the IS-444C/471C needs to be<br />
connected with a weld checker such as MM-370B or MG3.<br />
