Resistance Welder Inverter Model NRW-IN4200
The NRW-IN4200 inverter resistance welding model was designed to support precision weld of leads to terminal boards and leads to leads on electronic components. The built-in monitor eliminates the need for an external welding monitor. This model responds to changes during welding in real time due to the fast monitor feedback which improves the bond quality. The high stability welding current generated by the power supply is ideal for resistance welding of precision electronic parts.
