• Turning the power switch OFF does not deactivate the erroneous operation prevention
function.
• Initializing the welding condition and the internal function deactivates the erroneous
operation prevention function.

5.6 Performing Welding Operation
This section explains the procedure from the start to the end of the welding operation.
5.6.1 Operation of welding start
1.
Check that the welding conditions are correctly set and operate the torch switch to start the welding.
(
-
●
During the welding, the welding current is displayed on the left digital meter and the welding voltage
is displayed on the right digital meter both in a real time basis. This indication is the average value of
the output per approximately one second.
●
In TIG welding, arc start requires contact of the torch electrode with the base metal.
●
In DC STICK welding, arc start requires setting of the welding electrode in the electrode holder, and
contact of the electrode with the base metal.
2.
A series of welding operation is completed by the torch switch operation. (
-
●
At the end of welding, the average value of the welding current and the welding voltage at the last
second of the welding sequence is displayed on each digital meter in a flashing mode. (except for the
output at crater-filler)
⇒
Pressing any key on the operation panel during the flashing display will change the indication to the
set value.
⇒
The duration of flashing display can be changed by the internal function (F8).
⇒
When the welding time is short such as in the tuck welding, accurate value may not be displayed.

• The displayed average value is processed by the software. Note that the value cannot be
guaranteed as the control data for a measurement instrument.
• In using the welding power source for TIG welding, prepare a welding torch for TIG
welding by the customer.
• Perform the switch operation to TIG welding by the WELDING METHOD key when the
torch electrode is not contacted with the base metal.
