2. USE
Duty Cycle:
The duty cycle is the ratio of real working time among the whole working time. (Ten minutes is
one cycle.) For instance,60% of rated duty cycle is welding 6 minutes, then unloading for 4
minutes.When it operated under the rated elecrtic current. italso can operate althongh under high
rate of load sustenance at this time,the exchanging formula of rated duty cycle is following:
Dury cycle of really usrng current
(rated output current)²
x
rated duty cycle
=
(Really using output current)²
Welder Installation:
When installing, please notice the following items:
(a)
Please put it at a place (such as enough plate, low shake, out of 20cm distance to the wall).
(b)
Please put it at a clean,arid place without steel powder
、
dust and paints.
(c)
Please put it at a place which can avoid raining ,soaking and corro- ding of sea-water.
Connection:
1. Giound (a) At one side of the case there is the ground ends hedhind the case. please use copper
wire(above 14mm 2)to ground.
Rated input voltage 300-600V and grounding resistance is 10
Ω P
lease entrust a professional
petson(an electrician)to groundit.
2. Connection of power supply:
A welder is disposed an electricily-distributi on box with current - protection apparatus (such as
switch and fuse etc.), Is connected its output end to the input end of the welder through
cobles.please refer to the following granh about the capacity of electrcity - distriution box and the
section area of the cable. Specially notice the curreot puotection apparratus such as fuses etc.
Please use the correct capaciry and do not use the greeter one.
3. connection of weldign ends:
An end is connected to the oable of welding toreb and the other end is connected to the workpiece
through connetiong calbe
The workpiece must be grounded when operating in case for en suring safety.
[Notice items for connection]
When connecting cables etc.,please close the mains switch of the power -distribution box.
Every cable is connected by copper ends and then insulated with insulating tape.after fixed by a bolt
or a nut.
The cable of above list is copper-core cable.
Usage methods:
Operating according to the following sequence.
1. Please ensure the rared specification on the main board of this welder, then use i t in case fo r
avoiding wrong usage.
2.
A void over loading usage:
(1)
Badly over loading can burn the welder even though,it does not burn it can also reduce the
using life.
(2) Ovetioading can produce noise and make cuttent-adjust handle difficult to turn ete.
3. The connection between welding ends and cable should be firm,otherwise badly connection
will cause some parts heat,make ends and cables burn down. Please notice it carefully.
4. Too long output cable can cause a badly moving of current,add loss of electric power. Too old
cable and surface insulation damanged can produce ARC unstabilily so that must changed the old
one by a new one.
5. When operation finishes,must close the mains.
The sliding structure of the movable ironcore has been adjusted wholly and piease do not change
it without special requumenrs.
In summer,please do not use it under the direct sunshine for a long time and will do your best to
put the welder at a shadow place Please aviod to use it at great hurnid. fall steel powder and full
dust places.
8. During using it, the temperature of case will
rise very high(50
-70
),The insulation grade of coils is F, Please use it according to the Rated
Duty Cycle.
9 Notice items for applicable ratios:
(1) Do not use the welder(50Hz)at the area of 50Hz.
(2) The output current input KVA and power factor etc. will change although you can use the welder
(50Hz)at the 60Hz place.
10. Keep the stable voltage of the rnains and from
any aspect, the welder does not hope to change voltage of mains.
When mains voltage is lower than the input voltage of the rated voltage of a welder,it will cause:
(1) The current of welding is too low.
(2) Produce broken arc or unstable arc. When higher than the rated inpur voltage:
(1) weldign current is too great.
(2) Produce noise and it is difficult for turning the adjusting hand-wheel of current.
(3) Shorten the life of the welder
11. Please remember to put on a comect overcoat and applicable prorecting apparatus in ease for
avoiding an operator to get an accident hutt.
12. Please remove the plotecting cover then operate, when it operates with the dust cover of
polyethylene it can cause a hnrt.

notice items Make a repair to a welder at lease every six month as according to the following
points. During repair, please remember close the current switch of power-distribution box and the
current switch of the welder.
Using insulant resistant meter checks the insulant resistance between primary coil and secondary
coii, any coils and the ground at least sbouldabove 1M
Ω
.
Dust can reduce insulant function a nd make t he c oils o verheat s o t hat you should use presure air
to clean piled dust at coils and other parts.
3. Check in the conducting situation of the mains switch and there are
traces of overheat or not .If there is hurt on the surface of the conduct- ing, you should repair
plately.
4. Do your best to clean the dust on the surface of sliding of movable
iron core and the moving guide screw. Then pour into grease and the best applicable one is MoS2.
sliding part of the slideway uses self-lubricating material does not. need anv grease. Greasing will
make a bad effect on sliding. Please notice it.
5. Check in bolts and tightening situationsof-screws and if there are any fiexibilty then tighten them
completely.
