Inverter DC MMA Welding ( IGBT ) 40amps to 500amps
| Description: | ||||||||
| 1. The transformer core is made of high-tech material based on Nanotechnology. | ||||||||
| 2. The tri-proof(Water,dust and eroding proof)Cooling System raised the reliability and duty-cycle of the key Components. | ||||||||
| 3. Having the fan standby function. | ||||||||
| 4. With OCV as high as 70V,enables the machines to weld. | ||||||||
| 5. The duty-cycle is higher than 60% when the temperature of the operation surrounding is around 40. Capable to operate outdoors. | ||||||||
| 6. The maximum output efficiency is 85%. By using the advanced electro-circuit for power factor compensation,the max power factor could be as high as 0.93. | ||||||||
| 7. EMC electro-circuit added to reduce the pollution to the electric network. | ||||||||
| 8. With digital display of the welding current and remote control for option, | ||||||||
| 9. VRD function is added to meet the european requirment. |
