ROUTINE MAINTENANCE
Routine maintenance consists of periodically blowing
out the machine, using a low-pressure air stream, to
remove accumulated dust and dirt from the intake and
outlet louvers, and the cooling channels in the
machine. Also verify the STT
® Module fan is opera-
tional when the power source fan is activated.
CALIBRATION SPECIFICATION
Due to the nature of its operation, calibration of the
STT
® Module is not required. From a system perspec-
tive, the output calibration of the power source and
wire feeder should be performed as directed in their
respective instruction manuals.
When calibrating the power source voltage using the
Weld Manager utility, the actual output voltage should
be monitored directly at the output of the power
source (not the STT
® Module output). This is
necessary because the default calibration mode
senses voltage directly from the power source output
studs. The STT
® Module has no effect on the output
current calibration.
