TROUBLES
SOLUTIONS
The fault indicator
off, no HF discharge
rustling, and arc
striking effective
•
The arc striking transformer primary cable has a
poor touch with the power plate. Re-tighten it.
•
The discharging nozzle is oxidized or is too far.
Remove the oxidized membrane on the surface of
the discharging nozzle or adjust its distance to be
about 1mm.
•
The manual welding argon welding switch is broken.
Replace it. Some components of the HF arc stri-
king circuit is damaged.
•
Find and replace them.
Large splash of ARC
and very hard in the
burning of the
alkali welding rod
•
Wrong polarity, exchange the polarity of the earth
wire and the handle wire.
The fault indicator
on and no output
•
Maybe the over-current protection is activated.
Please switch off the device and then restart it
after the fault indicator is off.
•
Maybe the over-heat protection is activated. Do not
switch off the device but wait 2-3min, then the
device may naturally restore normal (the device of
pure argon arc welding does not have over-heat
protection function).
•
Maybe the inverter circuit is defective. Please plug
out the power supply plug of the main transfor-
mer on the MOS plate to restart the device.
1) If the fault indicator is still on, switch off the device
and plug out the power supply plug of the HF arc
striking power supply.
a. If the fault indicator is still on, it will indicate that
some field-effect tubes on the MOS plate are broken.
Find and replace them with the ones of the same type.

The fault indicator
on and no output
b. If the fault indicator is off, it will indicate that the
voltage
rise transformer in the HF arc striking circuit on the
power supply plate is broken. Replace it.
2) If the fault indicator is off:
a. Maybe the medium plate transformer is broken. Use
an electric bridge to measure the primary inductance
and Q value of the main transformer which should be
L=0.4-0.7Mh.
b. Maybe some the secondary rectifying tubes of the
transformer are punctured. Find and replace with the
ones of the same type.
20. SOLUTIONS AFTER REASONS FOUND
When this device fails or other peripheral components have defects, please
contact the local dealer for maintenance.
