please screw down it. If it is skid, please replace. Of ot
is rusty, please erase rust on bolt to ensure it works
well.
Quarter yearly examination
Whether the actual current accords with the
displaying value. If they does not accord, they should
be regulated. The actual current value can be
measured by the adjusted plier-type ampere meter.
Yearly examination
Measure the insulating impedance among the main
circuit, PCB and case, if it below IM
Ω
, insulation is
thought to be damaged and need to change, and
need to change or strengthen insulation.

5.2 Troubleshooting
●
Before arc welding machines are dispatched from the factory, they have already been debugged
accurately. So, forbid anyone who is not authorized by our company to do any change to the
equipment!
●
Maintenance course must be operated carefully. If any wire becomes flexible or is misplaced, it
maybe potential danger to user!

If there are some simple troubles of INARC 200 IDS welding machines, you can consult the following
overhauling chart:
S/N
Troubles
Reasons
Solutions
1
Turn on the power source,
and fan works, but the
power light is not on.
The power light damaged or
connection is not good
Test and repair the inside
circuit of power light Pr3
Power PCB failures
Repair or change power
PCB Pr2
2
Yurn on the power source,
and the power light is on,
but fan does not work
There is something in the fan
Clear out
The fan motor damaged
Change fan motor
3
Turn on the power source,
and the power light is not
on, and fan does not work
No input voltage
Check whether there is
input voltage
Overvoltage (input voltage is too
much or not)
Check input voltage
4
No no-load voltage output
There is trouble inside the
machine
Check the main circuit,
Pr1 and Pr2
5
No current output in the
welding
Welding cable is not connected
with the two output of the welder.
Connect
the
welding
cable to the welder
’s
output
Welding cable is broken
Wrap, repair or change
the welding cable
Earth cable is not connected or Check the earth clamp
