Latest generation LORCH welding machines are advanced digitalized high speed MICOR inverter systems. MICOR, stands for MIcro-COntrolled Resonant Technology.

Conventional welding inverters have relatively low voltage reserves. This means that an arc that destabilises in MMA welding cannot be stabilised again by a conventional inverter, causing the arc energy to drop for a moment and reduce the average arc performance. Just as if you have to briefly stop at the red lights all the time, it reduces your average speed.

The LORCH digital resonance inverter controls the welding process by microcontrollers monitoring current and voltage at 1.5 million times per second.

Called MICOR Boost by LORCH, this technology creates enormous voltage reserves, avoiding the drop in power input or shortening it considerably and increasing the average arc performance as a result. So like a turbo on a car, when welding you can quickly race across the light before it turns red or, if you have to stop anyway, you will be back to speed again very quickly afterwards. High speed equals greater efficiency and greater economy. The power consumption is up to 30 percent lower than that of comparable standard inverter systems with effective reductions in energy costs.

The voltage reserves have another equally important effect, a virtually perfect welding performance. The arc start is always reliable, saturated, and makes welding easier even on rusty or dirty metal. Experience a new, extremely stable and controllable welding quality and stay in control even when you lengthen the arc.

The resonance inverter technology is fundamentally different to any other type of inverter and offers greater efficiency in all situations. To date, there are only two welding machine companies in the world that have mastered this high speed, digitally controlled technology.
