VII. Troubleshooting for Frequently Asked Questions and
Equipment Maintenance
1. When turning on power switch, power indicator doesn’t light and fan doesn’t
run, and no response is seen to operation, then possible causes are as
follows:
a. No electricity for power source, please check to confirm;
b. Bad contact between power line and outlet, please make due repairing;
c. If fuse of equipment power supply is blown, please change fuse with
regulated nominal value.
2. If non-logic action is found, please make inspection as suggested below.
Contact our service staff if it still can’t be solved.
a. Check if connection of logic cable conductor is normal;
b. If two operational buttons are well connected;
c. If air supply is normal;
d. If emergency stop is reset and any error exists;
3. In the event of unstable logic control, check and handle it as follows. If not
successful, please contact our service department in case of failure.
a. Caused by the interference due to too close distance between the logic
wire and the power output wire.
b. The logic wire or logic board is in contact with the ground wire, or too
close to the ground wire.
c. The connecting plug-in units of the logic wire are in bad contact.
d. Power supply is impure, with interference factors.
e. Supply voltage fluctuates greatly.
4. Unstable welding quality.
a. Nonuniform shape, dimensions or material quality of the weldment;
improper design of fusion face; improper selection of welder power and
amplitude of welding head.
b. Unstable supply voltage; unstable air pressure of air supply.
c. Occurrence of frequency deviation protection or overload protection
during welding.
d. Unstable outputting of ultrasonic.
e. Because the power output of this welder is adjusted automatically
