As Tritium touched on: $$$.
IF we did everything that everyone had an idea about or a "comment" about, it would be ridiculously expensive to buy an Everlast. No one realizes the cost and work involved to make any changes, let alone a significant one like that.
Another, and more important one: DUTY CYCLE. Look at our duty cycles and compare to the duty cycle of most of the other welders in our class. Using a fan on demand is a "reactive" cooling system. Continuously cooling the components is a "pro-active" cooling system.
Not that long ago, most welders (and many still do contrary to the statement) had full time fans. You can trace the inclusion of fan on demand, largely with the observable decline in duty cycles published by the major companies as well.
We lead the class typically in duty cycle for our products...why would we want to take that step backwards?
It did seem like the older technology stuff had continous fan operation as my old Century,225A MIG welder had a fan that was continually on. I prefer my Millermatic 251 which has a fan on demand, is a smaller unit and has a higher output.
I realize this would add a little cost for the required relay to do this but I don't buy the idea of duty cycle argument as the fan could be turned on instantly as more power is demanded. Things don't heat up instantly and it's pointless cooling something that is already "cold".
If I decide on a PowerTig, I might add this feature as I like tinkering and don't like added noise or dust inside the machine. I can't argue with the 60% duty cycle.
