Problem:

Ⅰ、 The power supply indicator is bright and the wind machine doesn't turn, have not welding output.

Solution:
1.May be that the importation is wrong to connect on the 380 V power supply up, once resulted in to press a protection electric circuit a start, change to connect on the 220 V power , re- switch on then
2.220 V the electric power be unsteady(input lines is thin and long) or input line to take street on the charged barbed wire net, once resulted in to press protection electric circuit to start and increase charged barbed wire net importation the line path of the line; Tightly solid importation line crunodes, this kind of phenomenon shut down after 5-10 minutes re- switch on then and normally
3.Openned to shut power switch in a short time to once result in to press a protection electric circuit starting in a row and shut down to re- switch on after 5-10 minutes that can be instauration normal
4.The power switch arrives the power supply plank lead of line loose, tightly solid again.

Ⅱ、 The wind machine turn and output electric current while weld unsteady or be free from an electric potential machine a control

Solution:
1. The 1 K electric potential machine, the quality contains problem, should be replaced.
2. Various conjunction contact is bad, particularly is a plug-in etc., need to be check

Ⅲ、 The wind machine turn and the excrescent indicator isn't bright, didn't weld exportation

Solution:
1. Check various connect patch cord inside machine whether the contact is bad
2. Output and connect place have already broken road or get in touch with bad thing.
3. Measuring power supply plank to arrive MOS plank(plug-ins VH-07) electric voltage with the appearance is about DC308.
4. Lend support to power supply to have a green indicator on the
MOS plank such as not bright, please and dealer or the contact of our company
5. Control an electric circuit problem, please contact our company

Ⅳ、 The wind machine turn and the excrescent indicator is bright, haven’t welding output.

Solution:
1. May be to lead to flow a protection, turn off machine to need an excrescent indicator not bright, again re- switch on to then recover
2. May be wait for 5-10 minutes over the hot protection, the machine can automatically recovered.
3. May be negative to change electric circuit breakdown:
(1)Please pull out MOS plank the socket(close to the breeze machine VH-07) re- switches on up the provide of main transformer: if the excrescent indicator is still bright, then MOS plank ascend individual field effect tube damage
(2)If the excrescent indicator isn't bright
a. May be medium plank transformer damage, can measure main transformer entry-level electricity and Q value with the electricity bridge
b. May be a transformer to two times commutate a tube to broke through separately, check to seek and replace a tube of the same type.
4.May be a feedback electric circuit to break down
