Rear clearance for Lincoln Invertec V250-s?

admin

I'm getting ready to mount my Invertec V250-s under my bench, and I am curious as to how much rear clearance should be between the welder and the wall.  Any ideas on what the minimum would be to still allow adequate air flow?  Thanks!
Reply:Something like 1 fan diameter from the wall would seem reasonable.  Have you checked your owners manual?If you are mounting it under a bench up against a wall I would make sure that the back of the bench is far enough from the wall or cut an opening  at the back of the benchtop to allow the hot air from the fan to rise up and disperse and not be trapped under the bench.  The cooler that electrical equipment runs, the longer it will last."The reason we are here is that we are not all there"SA 200Idealarc TM 300 300MM 200MM 25130a SpoolgunPrecision Tig 375Invertec V350 ProSC-32 CS 12 Wire FeederOxweld/Purox O/AArcAirHypertherm Powermax 85LN25

Reply:Thanks for the information.  I'm trying to get it mounted under my bench to get it out of the way, especially since it has such a small footprint.  My benchtop is around 24" deep, and the overall depth of the Invertec is 18" or so.  I should be able to keep it at least 4" from the wall, and can always mount a couple of small fans beside the rear of the welder to help dissipate heat out of the cooling fans.  Worst case is I can always pull it out from under the bench, say if I am running it pretty hard on stick mode.
