• Post a sign at the installation site to say
“WELDING EQUIPMENT IN USE, DO NOT
TOUCH” to prevent other people to come and
be touched.
• 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

maintenance instructions may create a risk of
electric shock or injury.
Each item listed below must be carefully chec-
ked before operation:
• Make sure that the welding machine has re-
liable earth connection.
• Make sure that there is always sound output
and input wire connection without any short
circuit of the output side.
• Make sure there is always sound Insulative
protection of the input and output wire and
reliable connection.
Regular check needs to be conducted by the
qualified personnel after the welder has been
installed over a period of not later than six
months, which involves as follows:
• Routine cleaning needs to be done to make
sure that there is no abnormal loose parts hap-
pening in the welding machine while regular
dust cleaning is necessary.
• Check the welding cable to see if it can conti-
nue 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.
• Make sure whether there is enough power
supply to make the welding machine work pro-
perly and the input power must load the safety
protection device.
WARNING: Cut off the power supply before
opening the case to check.
IMPORTANT: Please do not hesitate to con-
tact the manufacturer or the agent for tech-

Arc Welder is an arc welding power source
manually operated by a single person. The
main parts of this machine are transformer,
rectifier and reactor. It is current stepless ad-
justment welding machine. It is characterized
by soft and stable arc, little spatter and good
welding performance. This machine can work
with acid electrode, alkaline electrode and cel-
lulosic electrode. It can get satisfied effect to
welding mild steel, medium carbon steel, mild
alloy steel, stainless steel and some nonferrous
metals such as nickelic alloy and copper alloy.
It can be used in ship building, boiler, pressure
container, construction, electric power, mining
machinery industries.
WELDER’S STRUCTURE
Arc Welding Machines adopts the movable box
like structures.
With a handle, wheels and hoisting ring at the
top of the case and four wheels at the bottom,
it is very convenient to carry and transport.
There are switch, power indicating light, cur-
rent adjusting hand wheel, output socket on
the front panel (AC/DC), and cooling fan, pow-
er input connection box and earth bolt on the
back of machine.
