Portable DC IGBT Inverter STICK/MMA 250AMP Welding Machines 4MM Welding Rod

Description

RSTAR ARC WELDING MACHINE DC MMA250
Advanced IGBT inverter technology
High inverter frequency greatly reduces the volume and weight of the welder.
Great reduction in magnetic and resistance loss obviously enhances the transformer efficiency and energy saving effect.
Working frequency is beyond audiorange, which almost eliminates noise pollution.
Leading control mode
Advanced control technology meets various welding applications and greatly improves the welding performance.
It can be widely used in acid and basic electrode welding.
Easy arc starting, less spatter, stable current and good shaping.
Perfect functional design
Non-adjustable hot start arc ignition obviously improves the arc ignition performance of the machine.
Self-adaptive arc force technology greatly enhances the performance of the machine in long-cable welding
