Designed for manual arc welding with stick electrodes in disturbance magnetic fields.
IST-201 is a unique welding equipment. The inverter noticeably speeds up pipeline repairs after in-line magnetic flaw detection.
With the welding inverter, a current switching algorithm in the welding circuit controls arc breaks, stabilizes its spatial position and ensures high quality welded joints under magnetic disturbance effects.
IST-201 is an electronic device connected to output terminals of a single-arc welding rectifier (or apparatus) with a negative external I-V curve.
