2. The cable must be connected with copper terminal .Please use insulating
tape after fixing it with bolt and nut.
Operation instruction
Operate as follows
1. Switch on the distributer box and power.
2. Turn on the power switch of welder
Turn the switch handle at 230v or 400v

4.Operate welding Wear proper clothes and protective appartus
5.End operation
6.Turn off the power of welder
7. Switch off the distributor box.
SAFETY ITEMS
Read this manual carefully before using in order to avoid accident. Incorrect
operation will cause three different degrees injuries . Signs in this manual
indicate it.
Caution Sign Caution Term Content
Warning Wrong operation will lead to serious injuries or death .
Caution incorrect operation may cause grave injury or potential accident.
Attention Wrong using may cause middle- degree injury or destruction
of matters.
The above serious injuries refer to those which need long-term treatment
in hospital caused by sight damnification , wound (high - temperature or
low-temperature) injury . Electric shock , fracture, poisoning and so on ;
and light injuries means burn or electric shock without long-term curing;
destruction of machine.
The following signs show ( must do) and ( forbid to do )
Compei must do
Prohibit Forbid to do
Dangerous
To avoid serious body injury caused by accident, you
ought to observe the following items .
1. The construction of inputing power source , the selection of the site
for machine , the upkeep of work place after welding and the handing
of waste should accord to the relecant rules and internal standard of
your company.
2. Irrelevant personals are forbidden to enter the site of welding,
3.Persons using heart stroke pacemaker can not draw near to welder in
use and the surrounding of welding site without the pernmission of the
doctor.
4. Let professional or expert person install, maintain and repair welder.
5. Let personnel who have the knowledge of safe use and technique
operate the machine,
6.Do not use the machine excepet welding.
Rate the hand - wheel increase , and the
current increase.
Rate the hand-wheel decrease , and the
current decrease

Dangerous
To avoid getting an electric shock , Please observe
the following
The following rules . Once you touch the electric parts, it may
cause lethal
1. Don not touch electric parts .
2. Let electrician ground the welder and machine tool according to the
regulation.
3. When installing and repairing , should turn off the power of distributor
box, and operate in five minutes.
4. Don not utilize the cable less of capacity with damaged insulated pro-
tective cover and exposed conductor .
5. Ensure the insulation of the joint part of cable .
6. Please don not use the welder without shell
7.Please use dry insulated glove.
8. Please use safe net when operation in high place.
9. Maintain and repair regularty, and use it after repairing well.
10. Please turn off all input power
11. Please use shock- proof device when using the machine in narrow
or high place.
Notice
To avoid accident such as fire , blasts , and crack
Please obey the following rules:
1.Dont not set flammable matters in welding site.
2. Don not weld near the flammable gas.
3.Do not draw hot machine tool near the flammable matter
4.The joint parts of the cable must be absolutely
5. When welding well , ground and wall , please clear away the flammable
matter on the back.
6. The cable joint with the side of machine tool should approach the welding
parts ,
7. Don not wold people with gas, sealed container and others .
8. Please set fire extinguisher near the site of welding.
Notice
Contacting the revolving parts may cause injury, please observe
the following regulation:
1. Do not use the welder without the shell .
2. Let professional person install, operate maintain and repair the machine
3.Do not approach your finger , hair , clothes and etc. To the revolving
parts such as cooling fan.
Notice
With the entry of splash and iron powder caused in welding
caused in welding and polishing into the inside of power, it
will lead to the deteriotation of insulation . To avoid the fire
1. Please separate the welding power from the operation of welding
and polishing.
2. Please maintain and repair regulatly to avoid the deterioration of the
insulation caused by the piling of dust.
3.When splashed iron power into the inside of power , please turn off the
switch of welder power and distributor box , then blow it clean by air.
UPKEEP & MAINTAIN
In order to prolong the service life of machine, please pay great
attention to its upkeep and repair. Please maintenance welder once at
1. Use resistance instrument to measure the resistance between ground
2. Dust may decrease the performance of insulation and make the winding
over-heated . Thus , you need use compressed to blow the dust in the
winding and other parts away.
3. Examine the contact state of power switch , if there is burnt on the surface ,
The surface , it should be changed.
4. Examine whether the bolt and nut is tight fixed . If they are loose , you
need screw it tighty.
Ca use d by t he d e te ri ot a ti on o f the p ow er ?s in su la tio n , pl ea se
ob ey th e ru le s :
and the primary winding, secondary winding, and each other winding. And
the resistance should be more than 1M
least 6 month as below points. The power of distributor box and welder
must be switched off.

5. Once the machine needs to be repaired , please inform the distributor
the model and product number as soon as possible.
NOTICE
1. Please confirm the rated specifications and then make use of it.
2. Avoid over-load usage
a. Serious over-load can burn machine, at least shorten the service life.
b..Over-_load may cause noise and make the rotation of hand- wheel
difficult.
3. The connection of cable and terminal of machine should be steady .
Or it will cause local running hot to burn the terminaI and cable.
4. Too long output cable will lead to impedient current circulation and add
electric power loss . If the surface insulation of cable is spoiled , the are
will be unstable . So we need change the old cable in time.
5.the power must be switched off after operation .
6. The internal movable iron- core sleek structure has been adjusted well.
Do not move it if no necessary.
7. Place the welder in the shade . Do not use the machine in the sun for a
long time.
8. The temperature of shell will rise in operation . The insulation of winding
belongs to F grade . Please use the machine at rated duty cycle.
9. Keep the voltage as stable as possible.
The voltage is lower than rated input voltage will lead to
(1) The welding current is too low
(2) The arc will break or be unstable.
The voltage is higher than rated input voltage will lease to
(1) The welding current is too high
(2) Make noise.
(3) The current adjusts the rotation of hand wheel hard .
(4) Shorten the service life ot welder.
10. Please remember to wear suitable protective apparatus in case
of accident.
