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 become
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 ig-
nite 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
Unlike the traditional welder, the reversible
welder belongs to the scientifically sophisti-
cated product which uses the modern electronic
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 contact our company for the techni-
cal 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. Immediate
cleaning is needed if there is an accumulation
of dust. Under normal circumstance cleaning
is only required once a year unless there is too
E N G L I S H •
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 before
dust removal. Never tamper with wire or dam-
age the component parts when cleaning.
TRANSPORTATION
This welder has a box-shaped structure, there-
fore, secure it firmly during transport and make
sure that the packaging is the standard for this
type of structure.
When storing or transporting, try to avoid
exposure to rain. When loading, put the "AT-
TENTION" label on the packaging. It is recom-
mended to keep it in a dry place with good ven-
tilation to avoid humidity, gases and dust during
storage. The tolerable temperature ranges are
-25 ~ 55 ° C, and the relative humidity can not
be higher than 90%.
Once the packaging is opened, it is suggested to
repack the product as a requirement for future
storage or transfers.
