INSTALLATION PREPARATION
• Careful precaution must be taken to keep the
operator and the machine from the foreign
materials falling from up above.
• The dust, acid and erosible dirt in the air at
the job site can not exceed the amount re-
quired by the norm (excluding the emission
from the welder).
• The welder must be installed in the place
where it can not be exposed to sun and rain.
Also it must be stored in less humid place with
the temperature range at -10~40˚C.
• There should be 50 cm space about for the
welding machine to have good ventilation.
• Make sure that there is no metal-like foreign
body to enter the welding machine.
• No violent vibration in the welder's surround-
ing area.
• Make sure that there is no interference with
the surrounding area at the installation site.
• Make sure whether there is enough power
supply to make the welding machine work
properly. Any power source required to access
the welder must be installed with some protec-
tive equipment.
• The welder should be installed on the hori-
zontal surface and if it over 15°, there should
be added some anti-dump set.
REPAIR
• Repair of Arc Welding should be carried
out only by qualified personnel. The repair or
maintenance performed by a qualified person-
al can create risk of injury.
• When repairing the machine using only gen-
uine replacement parts. Follow the instructions
in the maintenance section of this manual. The
use of unauthorized parts or failure to follow
maintenance instructions may create a risk of
electric shock or injury.
SPECIFIC SAFETY RULES FOR
ARC WELDERS
• This DC Inverter Arc Welder is an electronic
product whose spare parts are very tender, do
not change or adjust with a rush otherwise the
switch will be damaged.

• Check the connection to see if it is well con-
nected, whether the earth (ground) connec-
tion is reliable, etc.
• Fumes and gases produced when welding
are hazardous to health. Make sure to work in
places where there are exhaust or ventilation
facilities to keep fumes or emissions away from
the breathing zone.
• Please remember to keep arc rays away from
the other nearby people when welding. This is
only due to the interference from arc rays.
• Never allow anybody else other than the
operator himself to dislocate or modulate the
welding machine.
• Never allow the people with the cardiac
pacemaker or any other things which are sus-
ceptible to the electromagnetism to get close
to the welding machine, which has interfer-
ence with the pacemaker's normal function.
• The welder can not be used for pipeline ice-out.
• Over-load is forbidden. Please noted the
rated continuous loading factor
• Make sure that the welding machine has reli-
able earth wire connection;
• Make sure that there is no short circuit con-
nection with welder's both outputs;
• Make sure that there is always sound output
and input wire connection instead of exposing
it outside.
Regular check needs to be conducted by the
qualified personnel after the welder has been
installed over a period of six months, which in-
volves as follows:
· Routine cleaning needs to be done to make
sure that there is no such abnormal condition
as loose connection happening in the weld-
ing machine.
· The external parts installed with the welder
must guarantee that the welder works prop-
erly.
· Check the welding cable to see if it can con-
tinue to be used before it is worn out.
· Replace the welder's input cable as soon as it
is found to be broken or damaged.
