OPERATION INSTRUCTIONS
WARNING: To properly operate the welder
can assure the welder to work satisfactorily
and can prolong welder's operating life. When
using the welder, please make sure there is a
good connection of input, output and earth
(ground) before connecting the power source.
WELDING
Connect the power supply cord and welding
output cable according to the operator's man-
ual and then connect the power supply, finally
turn on the switch, and the fan starts working.
WARNING: When there is some distance
between the welder and the work piece, the
sectional dimension of the welding cable must
be made bigger just to keep the welder output
potential drop out not more than 4V.
WELDING CURRENT PRESETTING
Turn the hand wheel to move current indica-
tor to value needed. After presetting, do the
testing to make sure the preset current is cor-
rect. Turn the hand wheel to adjust current, if
fine adjustment is needed. Then start welding.
NOTE: Electrode burns at high temperature.
Please do not use hand to replace it. The re-
placed electrode end should be placed in a
metal container. Do not use the electrode
holder to clamp the electrode coating.
SLAG REMOVAL
When the welding job is finished, please use
the special slag hammer to knock off the slag
on the surface of welding rail.
NOTE: Only until the slag cools off and be-
comes hardened can the removal work starts.
To avoid the slag injuring people, never point
at the nearby people when you remove slag.

MAINTENANCE
WARNING: The welder voltage is always
higher, so the safety precaution should be
taken before repair to avoid accidental shock.
Switch off the power source each time when
conducting the examination job. The untrained
people are not allowed to open the case.
• Arc welders are a kind of portable and move-
able arc welding machine. Right performance
and maintenance may prolong its operating
life. Only the qualified personnel are allowed
to be in charge of repairing. It is strongly rec-
ommended customers contact with our compa-
ny or agent for technical, repairing, accessories
supply and service when they feel unable to
work out the technical hitch or problems.
•Before conducting the repair work, the power
should be cut off first.
• The newly installed welder or which haven't
been in use for some time needs to be surveyed
the insulation resistances between each wind-
ing and every winding to case with millimeter,
which can not be less than 2.5 MΩ.
• Keep from the rain, snow and long term ex-
posing to sunlight when welder is used out-
door.
• If the welder is not in use either for a long
time or temporarily, it should be kept dry and
have good ventilation to free it from moisture,
erosible or toxic gas. The tolerable tempera-
ture ranges from -25 to +55°C, and the relative
humidity can not be more than 90%.
• Regularly check the input & output cables of
welder to guarantee them right and firmly con-
nected and avoid them being exposed. Check
should be taken once every month when fixed
using and every check taken when removing.
• Dust removal is needed every year. Check
the machine's fasteners, moving-iron, current
regulation screws, etc to make sure there are
no loose connection problems.
INSTALLATION
Arc welder's case protection grade is IP 21S. It
is forbidden to put in a finger or insert a round
bar less than 12 mm (metal bar in particular)
into the welder. No heavy force can be em-
ployed on the welder.
