2.2.2.
Unique control circuit of welding dynamic characteristic, stable welding arc, excellent spot welding, less
spatter, nice shape, high welding efficiency.
2.2.3.
Molten globule can be removed after welding. With high no-load voltage and slow wire feeding on
striking arc, arc striking success rate can be increased.
2.3. Perfect function design
2.3.1.
With synergic MIG, welding parameters can be automatically selected based on wire feed speed.
2.3.2.
Four welding modes include MMA, lift TIG, DC MIG/MAG, digital control and humanized operation
panel is available.
2.3.3.
Functions such as accurate preset current/voltage, 2T/4T operation mode, synergic, gas selection, wire
diameter selection, electronic inductance adjustment, and on-demand fan and so on are available.
2.3.4.
Effective protective functions including over-current, overload, current sharing, etc are available.
