Upon arc starting, keep proper
distance away from the work-
piece and the distance should be
consistent with the diameter of
covered electrodes in use.
In the process of welding, please
do your best to keep this distance
unchanged.
The angle between covered
electrodes and working direction is
kept within the range of 20-30°.
If the output cable is excessively
long, the electric current may be
lowered down, which may result in
poor performance of welding.
The voltage of the power shall be
kept as steadily as possible for the
alteration of voltage may affect the
use of the welding machine.
If the voltage is 10% lower than the
rated input voltage of the welding
machine, it may result in:
Excessively low current to the
welding machine;
Arc breaking or poor stability of
the arc.
If the voltage is 20% higher than
the rated input voltage of the
welding machine, it may result in:
That the protection lamp is turned on;
That the welding machine canêt
work normally.
The arc light is the reason that
causes inflammation of the eyes and
scald of skin.
Splashing and slag cause the injury
on eyes and scald.
Please wear an eyeshade with
proper light shading ability or a
welding mask.
