• 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 equipments.
• 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-
ano 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
• 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.
