elding Operation
•
Other welding process
1.
Check that the welding JOB are correctly set and carry out the following operation to start the welding.
●
For TIG welding: Contact the torch electrode with the base metal, and then raise the torch.
●
For MMA welding: Contact the electrode with the base metal, and then raise the electrode.
During the welding, the "Welding time" and "Heat input" are displayed on the LCD panel both in a real time basis.
During the welding, the LED for the welding sequence being carried out flashes.
2.
Welding operation is completed by the following operation.
●
For TIG welding: Complete the operation by separating the torch electrode from the base metal.
●
For MMA welding: Complete the operation by separating the electrode from the base metal.
The LED for the welding sequence changes to the light-up mode.

•
If the TIG valve controller (optional accessory) is used, the start and completion of the
welding operation can be controlled by the torch switch operation. (
5.6.2
Operation during welding
This section explains the operation requiring adjustment of welding current/voltage during the welding. The welding
current/voltage can be adjusted during each sequence such as welding under start condition, welding condition, or crater
condition.
T I P S
•
When the analog remote control (optional) is connected, the welding current/voltage under
the welding condition cannot be adjusted on the operation panel. Adjust the welding
current/voltage for the welding condition at the analog remote control.
•
If the TIG valve controller will not be used in TIG welding, be sure to shut off the gas after
completion of welding.
There is a risk of suffocating if closing the gas is forgotten in case opening/closing of
the gas is done manually.
CAUTION
•
After five seconds have passed after switching the welding process to "DC TIG" or
"MMA", the safety voltage (approx. 15 V) is automatically provided. Before switching the
operation, make sure that the torch electrode (welding electrode) is not in contact with
the base metal.
