WARNING! BEFORE USING THE WELDING MACHINE READ THE INSTRUCTION
MANUAL CAREFULLY! FOR QUALIFIED AND SPECIALLY TRAINED PERSONS
ONLY AFTER PROPER READING OF THIS MANUAL IS ALLOWED TO USE AND TO
MAINTAINTHIS WELDING MACHINE.
The detailed description, safety rules and all required information necessary for proper operation
and maintenance of FUBAG welding machine are provided below. Keep this instruction manual by
machine and refer to it by any doubts concerning safety operation, maintenance storage and
handling ofFUBAG weldingmachine.
1. Safety perationo
It is highly recommended always to follow the safety rules. Wear protective clothes and
special means to avoid injuries to eyes and skins.
Use the welding mask or special protective glasses while working with the welding
machine. Only by viewing through the filter lens on the welding mask your eyes are
secured by your operation.
Prevent the sparks and spatter from harming your body.
-
Under no circumstance allow any part of your body to touch the welder's output bipolarity
(torch and work piece).
Do not operate under water or more humid place.
-
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.
There will be high temperature when welding work piece, so please don't directly touch on it
-
No touching on the output connection or any other electrification parts while welding.
-
No touching on the electrification parts after turning on the power. Cut off the power supply
after operation or before leaving the welding site.
No welding in the dangerous site where easily get an electrical shock.
-
No welding for the container loaded inflammable or explosive materials.
-
Safe measures should be adoptted while operating in high place to avoid accident.
-
No entering the welding site for persons not concerned.
-
Welders possible have electromagnetism and frequency interference, so keep away people
with heart pace or the articles which can be interfered by electromagnetism and frequency.
WARNING. The welder voltage is always higher, so the safety precaution should be taken
before repair to avoid accidental shock. Switch off the power supply before each type of
maintenance work. The untrained people are not allowed to make maintenance of the
machine.

Check the connection of input and output cables and the earth (ground) connection, etc.
Maintenance should be conducted by the trained personnel.
The newly installed machine or the welder not in use for some time needs to be checked by
-
multimeter have the right insulation resistance between each winding and the case.
When the welder is used outdoors, it should be kept from rain or long exposure to the sun.
Check is needed from time to time to make sure the welding cable is in good condition if the
-
welding machine is in frequent use. Check at least once each month if the welder is in
regular use. It is necessary to check when the welder is in mobile use.
If the welder is not in use either for a long time or temporarily, it should be kept dry and have
-
good ventilation to free it from moisture, erodible or toxic gas.
- 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 .
Dust removal is needed every year. Check the machine's fasteners, moving-iron, current
-
regulation screws, etc to make sure there are no loose connection problems.
The dust, acid and erodible dirt in the air at the job site can not exceed the amount required
-
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.
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.
Electrode must be taken down from holder when no welding.
No violent vibration in the welder's surrounding area.
Make sure that there is no interference with the surrounding area at the installation site.
The welder should be installed on the horizontal surface and if it over 15°, there should be
-
added some anti-dump set.
Take measures to prevent wind while operating in the strong wind since the welder is gas
-
shielded. The wind speed is limited below 1 0 m/s, or the wind shield device must be loaded.

Safety Check:
Each item listedbelow mustbe carefullychecked beforeoperation:
Make sure thatthere isno short circuitconnection withwelder's bothoutputs.
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 welding machine has
been installed overa longperiod or re-operation, whichinvolves as follows:
Check the weldingcable tosee ifit cancontinue to be usedbefore it is wornout.
-
Replace thewelder's inputcable as soon asit is found tobe broken or damaged.
-
Make sure whether there is enough power supply to make the welding machine work properly.
Any power source required to access the welding machine must be installed with some
protective equipments.
Please do not hesitate to contact us for technical assistance whenever you come across the
problems youcan notwork out or youmay deem difficult to fix.

3. Description
MIG Series Inverter is designed to be used with the advanced IGBT (Insulated Gate Bipolar Tube)
and rapid recovery diode as its main control and transfer components and assisted with the
specially developed control circuit. It is available to MIG ( both CO gas-shielded welding and fluxcored welding) and stickwelding. The continuous wirecan form welding seam metalafter melting so
as to connect the wok pieces each other. The melting electrode gas protects the welding district
easily, so it is easy to operate & observe the whole working process. Its characteristics are high
produce efficiencyand easy to carryout all-position welding.

4. Welder’s Principle
The welder acquires 220V single phase industrial frequency DC power source through the power
switch SW101 and rectify through single phase rectifier bridge B1 and then filtered through
capacitor C1, C2, C3, C4 to get the DC current. The 20 KHzAC current is got through the IGBT (Q1,
Q2, Q3, and Q4) all-bridge inverter. Then this alternating current, transformed by the intermediate
frequency transformer and rectified by quick recovery diode ( D4, D5, D6, D7), outputs the stable
direct current for the welder immediately after it has been filtered by the reactor L2. The wire feed
speed can be stepless adjusted through the speed adjust knob. The welding current is easily
influenced from the wire feed speed, usually the faster the wire feed speed thebigger theAmp value
under the samevoltage.

The torch iscomposed bytorch stand,connecting cableand handle.
Torch stand isthe interface of torchand wire feeding device.
Connecting cable: covered bynylon pipethe liner is loaded in thecenter of coreless cable. Theinner
part of liner is the passage for wire feeding. The space between liner and coreless cable is the
passage forshielded gas.Coreless cable is thepassage for current.
There is a gooseneck installed in the handle of the torch. In the back part of the torch there is a
connecting with the coreless cable and in the front part is a shunt. The shielded gas distributes via
the shunt and forms well-proportioned air current in the nozzle, and then spurt out in a form of air
hanging. Setwith asensitive switch on thehandle to control thewelding current.
Notice:
-
Must cut offthe power before assemble/disassembletorch or replace thecomponents.
-
The nozzle must be replaced in time on the condition that welding quality was influenced when it
burned tosome extent.The distributor oftorch must be replacedwhen it ruined.
