Question about Miller Trailblazer 302 Welder Generator 907217 907216
Sounds pretty normal. These units are not rated to weld continuously. They might only be rated at 5-10% for cheap welders and longer for better ones. They are never designed to run continuously. You need to get into the higher end ($$$) before you get that ability.
You can try to blow cool air into the unit to help it cool. Sometimes this can extend the work time.Basically you can try that or work to your temp cut off limit as you have been or upgrade to a better unit. That is about all you can do.

Help 5 Display Indicates the right side of the unit has overheated.
The unit has shut down to allow the fan to cool it. Operation will continue when the unit has cooled.
If unit overheats, output stops, a Help 5 message is displayed, and cooling fan runs.
Wait fifteen minutes for unit to cool.
To avoid this problem Reduce amperage or voltage, or duty cycle before welding.
