1. E lectric welding machine like has inserts the wrong power source, will not be able to revolve, automatic protection function.
2. T his welding machine use ends, when circular telegram the human contacts the electric conduction position not be able to hit the human actually.
3. W eldings splashes slightly stable

Stability:

1. Q uality is steady.
2. A rcs are stable, can't break the arc.

The electric welding machine when waits for an opportunity, the power is very small probably is 50W, when welding the efficiency reaches as high as 85%, compared to other welding machine efficiency 45% high 40%. Meets ARC200, 4.8KW uses 4 hour computations every day, uses electricity 19.2 degrees, other welding machine use electricity 36 degrees. Uses electricity 36 degrees.
