CO2 gas shielded welding machine /

IGBT inverter CO2 gas shielded welding machine and manual combination welding machine

 

Characteristics and application:

1. Simple operation: Digital display meter, welding current and voltage preset accurate.

Easy to be matched in current and voltage, a wide application range.

2.  Excellent property: Waveform control technology, small spatter in welding; with acr control function, ensure no arc crater after welding.

3. Economic, light, portable: high rated duty cycle, long time consecutive welding is available. High working efficiency, save power and energy. Output cable is long to 30 meters, applicable in long distance operation.

4. Good site suitability: All metal casting in resistance of dust, impact and shock; New created welding gun and wire feed structure with better stability, better welding wire feed property.

5. Application industry: ship-building, storage tank, engineering, machinery, auto, motorcycle, iron furniture, pressure vessel, steel structure, bridge construction and other automobile welding industry.
