QUESTIONS TO BE RUN INTO DURING WELDING
Fittings, welding materials, environment factor, supply powers maybe have some impact in welding. User must try to
improve welding environment.
A. Arc-striking is difficult and easy to pause:
1. Make sure quality of tungsten electrode is high.
2. If the electrode is not dried, it will cause unstable arc, welding defect increases and the quality is down.
3. If use extra-long cable, the output voltage will decrease, so please shorten the cable.
B. Output current not to rated value:
When power voltage departs from the rated value, it will make the output current not matched with rated value; When
voltage is lower than rated value, the max output may lower than rated value.
C. Current is not stabilizing when machine is being operated:
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. When use MMA welding, too much spatter:
1.
Maybe current is too big and stick’s diameter is too small.
2. Output terminal polarity connection is wrong, it should apply the opposite polarity at the normal technique, which
means that the stick should be connected with the negative polarity of power source, and work piece should be
connected with the positive polarity. So please change the polarity.
MAINTENANCE
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 inner-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 inner-machine, if them enter into machine, please dry inner-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.
