That supplied voltage is different from the rated will lead to unconformity of the
output current and the adjusted current. When Supplied voltage lower than the rated,
the max output current will be lower than the rated.
C
、
Current is not stabilizing when machine is been operating.
It has something with factors as following:
1) Electric wire net voltage has been changed
；
2) There is harmful interference from electric wire net or other equipment
。
D Welding gap has air hole.
1)
Check the gas supply loop leaks or not.
2)
Surface of mother material has oil, stain, rust, lacquer or other impurity.
MAINTENANCE
CAUTION
：
Before Maintenance and checking, power must be turned off, and before
Opening the housing, make sure the power plug is pulled off..
1、
Remove dust by dry and clean compressed air regularly, if welding machine is
operating in environment where is polluted with smokes and pollution air, the
machine need remove dust everyday.
2
、
Pressure of compressed air must be inside the reasonable arrangement in order to
prevent damaging to small components of inter-machine.
3
、
Check inter circuit of welding machine regularly and make sure the cable
Circuit is connected correctly and connectors are connected tightly (especially
insert connector and components). If scale and loose are found, please give a
good polish to them, then connect them again tightly.
4
、
Avoid water and steam enter into inter-machine, if them enter into machine,
Please dry inter-machine then check insulation of machine.
5
、
If welding machine will not be operated long time, it must be put into packing
Box And store in dry environment.
6
、
When wire machine operates for every 300 hours, the electric carbon brush and
armature rectifier should be polished, the reducer should be cleaned, and
lubricator should be added to the turbo and bearing.
