Cool down?

[essen48183]

I just purchased an everlasting 250ex. Is it ok to power off after welding, or is there a certain amount of time I should leave it on with the fan running?

if its hot outside i leave my 250 run for a few minutes after welding

Personally, I would. I try to keep my electronics as cool as possible and if I can spare the couple of minutes to allow the fan to run, I do it.

I'd call it 10 minutes to be on the safe side.

Like Zoama said 10 minutes. I leave my PP205 on while I clean up and it's turned off right before I put it away.

I always leave anything with a fan that cuts on/off based on temperature on until the fan shuts off (my MIG welder), my plasma cutter I just let it run for a few minutes after I am done with it, unless I only used it for a very short period. I always leave it on until the air solenoid shuts off air to the torch at a minimum, normally a few minutes longer.

My MIG welder does not have a fan running at all once the cooling fan shuts off, so I shouldn't have any worries with it.

I usually base the time I let it run on what I have been doing with the welder. A quick tack or two and I will let it sit for 10-15 seconds and shut it off. If I have been blasting away on some heavy aluminum I might let it run for 5-10 minutes.
