NBC-1000P Inverter Hi-speed Automatic Gas-shielded Welding Machine
NBC-1000P is the auto inverter GMAW welding machine Sichuan Morrow Welding Development Co., Ltd. Based on the original NBC series of semi-automatic welder and MZ7 series of auto submerged-arc welding machine. It is specially developed for box beam use. With pulse functions, its molten depth is deeper and welding seam and is more beautiful.
Features
■ IGBT module all-bridge soft-switch inverter technology, high efficiency, energy saving
■ Automatic protection from phase lacking, over-current, over-heat, over/under-voltage
■ Adopt the double-closed-loop system to control arc, arc burns stably
■ Accurate preset of welding current, voltage and march speed
■ Super low-spatter welding to 4mm, 3.2mm SAW wire, and narrow-gap welding
■ Hi-speed pulse big wire welding, high speed,deep molten depth
Technical features
- Using our high-speed pulse gas shielded welding, we don’t need to add bearing block as the general box beam welding, don’t need do bottom welding, and we can also avoid the problem of hardly removing slag in the first or second submerged arc filling welding, thus greatly reducing production costs and further improve the production efficiency.
