6.2 Steps after welding operation
6.2.1 Shutting off Gas
Close the main valve of the gas bottle first of all, and then
take the residual pressure out of the pipe through the gas
checking process.
6.2.2 Shutting off power
6.2.3 Precautions for winter season (when using the water-cooling torch)
In case the special cooling water (Pana-coolant K: See
page 5-5) is not used yet, do not forget to take freeze-
proofing measures after every welding operation to prevent
possible breakage of the flow-rate switch caused by freez -
ing. (For example: Take the cooling water out of the water-
circulating path including the flow rate switch.)
Important
To allow the inside of this product to cool down, turn the power off at least 5 minutes after the com -
pletion of welding operations.
(1) Turn off “POWER” switch.
(2) Turn off the switch of the distribution box.
Note
At that time, even if the “Err-5: Low primary voltage”
appears, it does not mean that an error has occurred. (It just
means that the reduction of the primary voltage has been
detected due to the shutdown of the power switch.)
