Excellent Arc Start

Very excellent performance and suitable to wide application of thin, thick welding and automatic welding thanks to the arc start by super high speed PMW control system.

High Quality Function

The high speed inverter control guarantees quality welding by maintaining a stable arc even with current keeps as low as 5A.

The selected welding current keeps stable despite variations in input voltage or ambient temperature and the steady arc ensure high efficiency regardless of hand-trembling while welding.

Realization of High Quality Welding

High Quality DC TIG Welding

Kobewel’s original inverter realizes a complete wave from so that excellent arc stability enables quality welding and helps weld nicely the corner of the thick plate.
