1. Industrial grade heavy duty welding machine with unique anti-jamming protection technology has outstanding work performance under environmental extremes such as high temperature and dusty environment etc.
2. it has considerable power saving effect the main contactor can be automatically disconnected after 3 seconds’lidless if loose sensitive switch.
3. it has ending arc function,after the welding of thick welding wire,loosing sensitive switch,the voltage of arc and feeding machine will beautomatically declined to fill in the arc crater.
4. it can weld beautiful aluminum weld pass if equipped with new devices,including electrode feeding machine and welding torch.
5. suitable for welding of low carbon steel and alloy steel,can be used in ship buiding steel structure,machinery and hardware industries etc.
