1-GENERAL REMARKS
ARC series welding machine is suitable for DC MMA, lift TIG process, which can weld carbon
steel, stainless steel, copper etc. Because of the ideal static characteristic and dynamic
characteristics, machines highlights are as follows.
1-1 Power source features
Highlights as follows:
- Single phase 220/230V power supply, portable design
- Rapid adjustment adapting to changes in the load, stable arc length, excellent
constant-current characteristics
- Low spatter
- Easily arc ignition
- High penetration power, pretty weld formation
- Reliable and durable with patented technology
- ARC II series can weld cellulose electrodes
1-2 Functional principle
This welding machine applies HF inverter technology. Single phase input power is rectified,
filtered, converted to AC by inverter, reduced by transformer, rectified by rectifier. Then output
adjustable DC current. This process greatly improves the welding machine’s dynamic
response ability and efficiency, decrease size and weight of transformer and electric reactor,
realize energy saving and consumption reduction.
