Good afternoon,
I'm having a problem with my 301D it starts fine, but after a while of running it runs hot and shuts off. The temp light comes on.
It dumps some coolant out on the trailer floor. The welder has low hr.
If anyone has had this to happen please enlighten me.
Thanks keep them rods burning.

I'd look into general engine troubleshooting:

Are the radiator fins clean?
Flush the inside radiator/cooling lines - maybe clogged
Does the fan run?
Replace the thermostat.
