SC2400 Operations ‐ Settings
SC2400 Power Switch/Power On
The power switch for the SC2400 is located on the right front of
the welder’s control panel. When the power is turned on to the
unit, the light on the power switch will be illuminated.
When the welder is turned on, the digital display will go through a
self‐diagnostic check. This takes approximately 3 to 5 seconds,
and then the digital display will show the last time and current
setting.
This denotes that the unit is ready to go.
When connected to the welder, the stud gun will actuate 3 times,
indicating that there is a good connection.

On the Control Panel, located below the digital display, is a row of diagnostic lights for the
welder.
