Mid-Frequency Inverter Resistance Welding Control • 300 amp primary output • Six feedback modes • Built-in current, voltage, power, time and pulse monitor • Primary short circuit protection • Triple pulse weld profile: W1, W2, W3, up to 19 pulsations per weld segment • I/O check screen • 5-way cascade option using MA-650A • Pre-weld check process tool • RS232 or RS485 communications • Compact design TYPICAL APPLICATIONS Key features Six Weld Control Modes Six different weld control modes allows you to select the best control mode for your application: primary limit, primary and secondary RMS, power RMS, voltage control, or pulse percent. Triple Pulse Weld Capability Provides flexible weld profiles allowing for three pulses in each weld cycle. Each weld segment may be programmed with upslope and down-slope and can have up to 19 pulsations in each segment. You can also change the control mode for each weld segment. Commutator fusing Wire termination Wide Current Range The ISB-300A inverter spot welder has a current range of .050 A to 20 kA making it possible to weld a large range of parts – from small, electronic components to sheet metal and copper bus bars – with the same welding control.
