6.6.5 Arc spot time
This section explains the details of arc spot and torch switch operation.
Selecting "ARC SPOT" by the CRATER-FILL key allows the machine in the main mode.
• Once current flows with the torch switch turned on, the current continues to flow during the Arc Spot
period (including the down-slope time in the Slope ON mode) even after the torch switch is turned off.
• The arc spot time is displayed on the left digital meter when pressing the SPOT TIME key, and is
adjustable by the parameter adjustment knob.
• Arc can be broken even in the Arc Spot period when the torch switch is turned off in the Arc Spot mode.
