a) Connecting the power source switch, and
the Power Indicator will Light bright.
b) Regulate the welding current potentiom-
eter to reach the value for welding;
c) Take-up the torch hand, aim at the welding
seam, use the stick contact with the work piece
and then the electric arc was ignited, i.e. you
can effect the arc welding at the same time the
(welding Indicator Light) bright.
REPLACEMENT OF ELECTRODE
Only when the electrode burns up to 1~2 cm
away from the electrode holder does it be-
come necessary to replace it with a new one in
order to proceed with welding.
REMARKS: Electrode burns at high tem-
perature. Please do not use hand to replace it.
The replaced electrode end should be placed
in a metal container. Do not use the electrode
holder to clamp the electrode coating. While
ignite the electric arc, you should scrap lightly,
or it may adhere to the stick.
REMOVAL OF SLAG
When the welding job is finished, please use
the special slag hammer to knock off the slag
on the surface of welding rail.
REMARKS: Only until the slag cools off and
becomes hardened can the removal work
starts. To avoid the slag injuring people, never
point at the nearby people when you remove
slag.
MAINTENANCE & SERVICE
Unlike the traditional welder, the reversible
welder belongs to the scientifically sophisti-
cated product which uses the modern elec-
tronic component parts combined with state-
of-the art technology. Therefore the trained
personnel are required for its maintenance.
However, due to the fact that there are very
few components to be easily worn out, it
doesn’t need regular service apart from usual
cleaning work. Only the qualified people are
allowed to be in charge of the repair job. It
is strongly recommended that customers con-
tact our company for the technical back-up or
service when they feel unable to work out the
technical hitch or problems.
THE MAINTENANCE INCLUDES
Dust removal. The service man must regularly
clean up the dust from the welder by the dry
compressed air (Air compressor or the similar
device). Meanwhile examination can also be
performed to make sure there are no loose
parts and components inside the machine. Im-
mediate cleaning is needed if there is an accu-
mulation of dust. Under normal circumstance
cleaning is only required once a year unless
there is too much dust inside the welder. If so,
cleaning needs to be done every quarter of the
year.
Keep the welder cable plug in good condition.
The Welder Cable Plug needs to be checked
from time to time. In its regular usage, at least
it has to be inspected each month. However, it
is necessary to check it every time when it is in
the mobile circumstance.
WARNING: If the main loop voltage happens
to be a bit higher, safety precaution should be
taken before repair to avoid accidental shock.
The untrained people are forbidden to open
the case. Power source needs to be cut off be-
fore dust removal. Never tamper with wire or
damage the component parts when cleaning.
