Problems During Welding
Fittings, welding materials, environment factor, supply powers maybe have something
to do with welding. User must try to improve welding environment.
No. Problems Solutions
1
Arc starting is difficult and easy to
break.
1. Make sure the quality of electrode.
2. If the electrode is not dried, it will cause
unstable arc, welding defect increases and
the quality is down.
2 Output current not to rated value
1. Make sure the quality of electrode.
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
3
Current is not stabilizing when
machine is being operated
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.
4 Too much spatter
1. Maybe current is too big and electrode
diameter is too small.
2. Output terminal polarity connection is
wrong, it should apply the opposite
polarity at the normal technics, which
means that the stick should be connected
with the negative polarity of power source,
and
workpiece should be connected with
the positive polarity. So please change
the polarity.
