Arc spot time
This section explains the details of arc spot and torch switch operation.
Selecting "ARC SPOT" by the CRATER-FILL menu allows the machine in the main mode.
•
In this mode, the torch switch remains to be ON for welding operation. When the arc spot time elapses, the welding
automatically stops.
•
The arc spot time is displayed on the left digital meter when pressing the SPOT TIME menu, and is adjustable by the
parameter adjustment knob.
•
Turning OFF the torch switch before reaching the arc spot time starts the anti-stick treatment from then.

•
In carrying out the arc spot welding, purchase the nozzle especially for arc spot (optionally
available). For details on the nozzle for arc spot, see the instruction manual of the torch.

Welding voltage adjustment
This section explains how to adjust the welding voltage. The adjustment of welding voltage can be carried out either by
the SYNERGIC mode or INDIVIDUAL mode.
T I P S
•
Some conditions such as synergic condition does not meet the appropriate level if a mixing
gas ratio of shield gas is not the specified value. (

Welding mode setting)
•
Even when the base material side/torch side cable or torch cable is extended, adjust to a
higher voltage setting beforehand in consideration of voltage decrease.
•
The voltage displayed during the setting or welding is the voltage of output terminal (base
metal side) between the wire feeder and welding power supply.
