wire #1 to red, wire #2 to
yellow.Thermocouple
The Miller Weldmaster T-500 and T-100 use a thermocouple to read the air
temperature just before it reaches the nozzle, or the ambient heat from the
wedge. The typical life expectancy of a thermocouple varies. The
thermocouple should be replaced if the machine does not maintain a constant
temperature of +/- 2 Degrees F (+/- 1 Degree Celsius) or heat elements burn out
prematurely.
Warning!
Only a qualified technician may perform any maintenance on
machine. This may be a Miller Weldmaster representative or someone
trained by a Miller Weldmaster representative.
Warning!
Machine must be disconnected from power source before any
maintenance may begin.
