Comparison in the inverter spot welder and power frequency AC spot welder
 inverter spot welder power frequency AC spot welder
Current characteristics 1, Pulse DC current.
2, Welding cycle min: 0.*5 ms(4kHz), high precision.
3, Constant current output, detect and feedback in every cycle.
4, Avoid the power fluctuations.
5, Accurate and Digitizing control.  1, Use the *0Hz power source, through a transformer.
2, *0Hz as the working frequency, welding cycle min: *0 ms.
3, Sine wave current, but a long zero between every half-cycle of the sine.
4, Heating aprosexia.

Long-term stability Good stability for long time, need not change any element in life time.  Sensitive to the power source line voltage, similar *0 times larger when it changes.

Welding speed Also named switching power supply, high welding speed, can weld ***0 times per minute
Suitable for automatic machine.  Longer welding time.
Affected by the welding circuit.
Energy saving  *0% less than power frequency AC spot welder Because of the long zero, welder heat can not focus.
Volume and weight  Smaller and lighter.  Heavy and occupy more space, 5times bigger than inverter spot welding machine.
Electrode influence Low loss, longer use time.  High loss.
Price Expensive for buying, cheap for using.  Cheap for buying, expensive for using.
