ROUTINE MAINTENANCE
Routine maintenance consists of periodically blowing out the
machine, using a low-pressure air stream, to remove accumu-
lated dust and dirt from the intake and outlet louvers, and the
cooling channels in the machine. Also verify the STT
fan is operational when the power source fan is activated.
CALIBRATION SPECIFICATION
Due to the nature of its operation, calibration of the STT
is not required. From a system perspective, the output calibra-
tion 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
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.
