Current
characteristics
|
1,
Pulse DC current.
2,
Welding cycle
min 0.*5ms(4kHz), high
precision.
3,
Constant current output,detect
and feedback in every cycle.
4,
Avoid the power fluctuations.
5,
Accurate and Digitizing control.
|
1,
Capacitance discharge curve.
2,
Welding time can not be changed.
3,
Current output depend on the line voltage which
is unstable, no detect or no feedback.
4,
Rough and Simple control.
|
|
Long-term
stability
|
Good
stability for long time, need not
change any element in life time.
|
Capacitance
is consumables.
Manual
detect and change new regular is needed.
|
|
Welding
speed
|
Also
named switching power supply, high welding
speed, can weld ***0 times per minute
Suitable
for automatic machine.
|
Need
time to charging the capacitance, so welding
speed is largely discount.
Faster and more
unstable.
|
|
Price
|
Expensive
for buying, cheap for using.
