11. Troubleshooting

Touching the current-carrying parts may cause a fatal electric shock or burn
injury.
To prevent a physical accident, such as an electric shock, burn injury, etc., make sure
to observe the followings.

Only educated and/or skilled persons who well understand the welding power source should perform trouble-
shooting work.

Make sure to turn off power switches of this unit, distribution box and all other related devices for safety reasons
before taking any actions for correcting an error.

As for the inside inspection, make it at least 5 minutes after turning the power off in consideration of electric dis-
charge from a capacitor.

When the power switch is turned off automatically, contact sales distributor or Panasonic rep-
resentatives without turning it on again.

The power switch uses a non-fuse circuit breaker. If over-current occurs for some reasons,
the power is turned off automatically (tripping). Do not turn it on again.

(It is ous to turn the power on again without removing the cause of such over-current.)
Notice Do not turn the power on with the top panel and/or side panel of this product removed.
The electromagnetic force may cause troubles (deformation, mechanical contact, etc.) to the inside devices and parts,
and may break them and/or affect their functions and performance.
