Attention:
" Turn the equipment off immediately if any other fault occurs
and can't be corrected, and give notice to our company or the local
vendor as soon as possible. Be sure not to repair it on your own to
avoid worsening the problem and causing unnecessary loss.
* When give notice to our company, please describe the problem as
detailed as possible so that you problem can be handled in time.
9. Possible problems during the welding process
The problems listed here are related to the fittings, welding materials,
environmental factors, and power supply. Please try to improve the
environment and avoid the problems occurring.
A. Difficult in arc starting and prone to arc breaking:
1)
Check if the welding ground clamp and the workpiece are in a good contact.
2)
Check if all the joints are in a good contact.
B. The output current can't reach the rated value:
The supply voltage diverges from the rated value so that the output current
value is not the same as the preset value. When the supply voltage is lower than
the rated value, the maximum output current of the welder is likely to be
lower than the rated value.
C. During the welding process, the current can't
be
kept stable:
The problem may be related to the following factors:
1)
The voltage of the power grid has changed.
2)
There is severe interference from the power grid or other electric
equipment.
D
Gas holes exist in the welding lines.
1)
Check if gas leakage exists in the gas supply loop.
2)
Check if any foreign substance such as oil, dirt, rust, or paint exists in the
surface of the base material.
