Status Indicator Lights
The status indicator lights monitor certain elements of the
power supply operation. See Figure 3-6.
The conditions monitored by some of the indicators are
independent of the welding process. Most of the indicators
light during the welding process to show the control
sequence executed by the power supply. The control
sequence is affected by the values entered into the timing
control switches.
The lights also notify you if any weld parameter settings
exceed pre-defined limits. See Figure 3-8 for an example.
D
Fixture
indicates whether or not the weld head is
properly attached to the fixture block. If it is not
connected, the indicator light is on. The power supply
will not start a weld cycle when this indicator light
is on.
D
Prepurge
indicates the prepurge cycle is active. The
Prepurge cycle occurs prior to arc start. This light
indicates that the shielding gas solenoid valve in the
power supply is energized, allowing the shielding gas to
flow to the weld head prior to starting the
welding cycle.
D
Start
indicates the power supply is in the arc start
portion of the weld cycle.
D
Weld time
indicates the weld cycle is in progress.
D
Downslope
indicates the downslope cycle is
in progress.
D
Postpurge
indicates the postpurge cycle is in progress.
The shielding gas continues to flow to the weld head,
and the rotor moves to the home position.
D
Rotor
indicates the rotor is in motion.
