APPLICATION: One Hipower HW400A welder allows to operators to weld at the same time. The secret is in the unique 10 pole rotor/split winding stator that creates a higher frequency output (300Hz), resulting in a superior weld. This split design permits two workers to operate at the same time with minimal mutual interference. Similar to have two welders in one; consuming less fuel, lower machine cost and reduced emissions per man-hour. The welder maintains a narrower current range generated by the higher no-load voltage, similar to having an onboard load bank. That means consistently advance quality welds. Meantime the winding generates AC current that can be used as 480V 3Ø and 120/240V 1Ø, allowing the operators to use power tools to grind, cut and drill at the same time it welds. When you choose the ECO operating mode, welding is accomplished at a lower operating speed (2100rpm), extending the service life of the engine. 30% less fuel consumption can extend the run time of the equipment to 18 hours on one full tank of fuel. industrial & military base camps. Each panel is carefully assembled to meet and exceed the highest safety standards in North America and other countries

MAIN FEATURES 1. Capability to use 5/32 (4.0mm) rods in dual operator mode. • High efficiency alternator makes it possible to perform 5/32 (4.0mm) rods in dual use. • There is almost no mutual interference (current fluctuation) between A and B. 2. Multi-process welding from stick welding to semi-automatic welding. By combining wire feeder, you can perform: • CV/CC

5. Remote control for constant voltage (CV) or constant current (CC) welding is available.


• You can adjust welding voltage or current easily by remote control with connecting a cord reel plug into a receptacle on the front panel. • You can connect 3 reels(90 meters max) to control remotely. 6. Micro-computers installed in the equipment can be used with the generating output.

• SS • Flux Cored • Air Carbon Arc • (CO2) • Flux-Cored welding besides stick welding. 3. Eco welding is achieved at lower RPM for reduced noise and fuel consumption. • When the output selector switch positions at Eco, the speed gets down to 2100min-1 but you can weld at 240A (Max).

WHAT IS ECO? The feature to reduce speed down to a half from regular speed is called Slow-Down feature for the purpose of low noise and low fuel consumption, when welding is not performed. Eco welding is the feature to perforM welding in good quality at Slow-Down speed. • In comparison with regular speed, fuel consumption decreased it by 30% at (60Hz). • Ultra Super Low Sound Level 4. Digital meters improve operation monitoring.


• Independent digital meters for welding voltage and current at both A and B sides are incorporated in the equipment. They prevent from welding fluctuation out of the setting values. • In addition to them, AC output voltage(3-Phase) and frequency meter in digital display strengthen monitoring feature.
