Section 7.2: Replacing Components

Module 7.2.1: Heat Elements

The Heating Elements used by the Miller Weldmaster T-500 and T-100are 

rated for 1000 hours of use at 1000 degrees F (537 degrees C).  Although longer 
heat element life is possible with proper maintenance, 1000 hours is the 
average.  If the Heat Elements fail prematurely, contact a Miller Weldmaster 
representative before replacement.  It is recommended that both elements be 
changed even if only one burns out.

1. Turn the Service Disconnect to the off 

position.

2. Disconnect the power cord from the 

power supply.  If the power cord is 
wired into the power supply, turn the 
power off at the junction box.

3. Remove the 3 sheet metal screws from 

the top of the element housing.

4. Carefully unplug the 2 Thermocouple 

leads, being careful not to pull the 
wires out of the leads. 

5. Remove the top covering of the element 

housing and slide it out of the way.

6. Remove the 2 pieces of insulation 

between the wire leads and the 
aluminum air divider.
