The 12v electric fan and shroud (for rice burner race cars) can not create the draw of air needed to cool. The machine in the pics has a nice big electric fan, but that is the complaint of the customer.
That is why it is ok to drop them not chop them. If Lincoln could have made it different they would have, but to date they are making them with the same design for a reason.
The machine in the pics will never be able to run pipeline. It will be for light use only. Stinks to spend that much time and money and not have a usable machine. JMO
