FINE SPOT WELDER IPB-5000A DC Inverter Welding Power Supply for Spot welding and Fusing FEATURES ■ Four control modes to choose from Optimum control modes for obtaining ideal weld quality can be chosen from; secondary constant current control, secondary constant voltage control, combination of secondary constant current and secondary constant voltage control, and secondary constant power control. ■ Two features for GOOD / NO GOOD determination The Comparator feature allows to set upper and lower limits around the measured value of up to four parameters; which are current, voltage, power and resistance, to assure process consistency. When those values reach out of the limits, an error signal or a caution signal alarms. The Envelope feature allows dynamic limits to be set around a monitored waveform to ensure the same resistance change occurs at the same rate for every weld. ■ Measurement of displacement value It measures how much an electrode moves down because of penetration to see displacement value and stops welding when displacement value reaches the set value. (Option) ■ Reduction of weld current ripple Current ripple is reduced to 1/3 of that with the conventional model. With the same effective current, the IPB controls the peak current to be in low value and keeps current constant. [ Weld current: 4000A
