A、The high open circuit voltage designed:

1)      The electric arc is more stable;

2)      Suited to welding 506 electrode;

3)      Suited to the low input voltage.

B、 Computer optimization design: The best proportion of wire and iron, reduce weight effectively and move easily.

C、 The special wind tunnel is designed: Overload capacity is strong, to be specially used in heavy industry.

D、The bottom of this welder adopt hermetic design: Easy to protect the winding of transformer, to be suitable for dirty environment.
