MIB-300A AC Inverter Resistance Weld Control

MIB-300A is an AC inverter welding power supply capable of up to 20,000 A output.

Compared to a standard AC welding power supply, AC inverters provide more controlled input of heat to the workpiece, minimizing potential damage to surrounding parts.

AC inverters also helps avert magnetization of the workpieces or of magnetic parts and prevent uneven welds due to the Peltier effect when welding dissimilar materials.

  • More effective control of heat input than standard AC welding power supplies
  • Reduced Peltier effect
  • Reduced magnetization of work piece and magnetic materials around electrodes
  • Secondary constant current control
  • Up to 20 pulses each for WELD 1, 2, 3
  • Interrupt function helps prevent over welding
  • Upslope and downslope functions improve energy input into workpiece
