Wrong voltage
1.Duty cycle is short circuit
2.RPM is wrong
3.Rotor line is short circuit
4.Generator line is broken
1.Check
2.Adjust the RPM to
rating
3.Repair
4.Repair
Can’t reach the
rated voltage
1.Exciting voltage is too
low
2.The load is too huge
3.Generator wire is
damaged
4. RPM is too low
1.Adjust the welding
current to the max
2.Decrease the load to
the rating
3.Repair
4.Increase the RPM
Voltage dropped
considerably
when loading
1.The wire between the
generator and load is too
long, or section surface is
too small
2.Principal windings and
loop are damaged
3.Load is ahead of the
power rating
1.Narrow the gap, and
make the wire more
thick
2.Replace the Generator
3.Decrease the loading to
the power rating
Welding current
is wrong
Welding winding is
damaged
Replace the Generator
Welding current
is too low
RPM is too low
Adjust accelerator and
increase the
RPM
